A new method, `to_exportable_module()`, was added to both feature extractor classes to return an instance of these new modules. The original `__call__` and `_torch_extract_fbank_features` methods were updated to use these exportable modules.

It provides transformations such as resizing, normalization, and conversion into PyTorch. Along with transformations, the `VideoProcessor` class also handles video decoding from local paths or URLs (requires [`torchcodec`](https://pypi.org/project/torchcodec/)) and frame sampling according to model-specific strategies. The video processor extends the functionality of image processors by allowing Vision Large Language Models (VLMs) to handle videos with a distinct set of arguments compared to images. It serves as the bridge between raw video data and the model, ensuring that input features are optimized for the VLM. diff --git a/src/transformers/models/videoprism/modeling_videoprism.py b/src/transformers/models/videoprism/modeling_videoprism.py index 83312d33216e..95792978f640 100644 --- a/src/transformers/models/videoprism/modeling_videoprism.py +++ b/src/transformers/models/videoprism/modeling_videoprism.py @@ -107,8 +107,8 @@ def __init__(self, config): self.pos_emb_shape = [self.image_size[0] // self.patch_size[1], self.image_size[1] // self.patch_size[2]] self.num_patches = self.pos_emb_shape[0] * self.pos_emb_shape[1] - def forward(self, pixel_values, interpolate_pos_encoding: bool = False) -> torch.Tensor: - batch_size, num_frames, num_channels, height, width = pixel_values.shape + def forward(self, pixel_values_videos, interpolate_pos_encoding: bool = False) -> torch.Tensor: + batch_size, num_frames, num_channels, height, width = pixel_values_videos.shape if not interpolate_pos_encoding and ( height != self.image_size[0] or width != self.image_size[1] ): # ! need to decide on this @@ -116,9 +116,11 @@ def forward(self, pixel_values, interpolate_pos_encoding: bool = False) -> torch f"Image size ({height}*{width}) doesn't match model ({self.image_size[0]}*{self.image_size[1]})." ) # permute to (batch_size, num_channels, num_frames, height, width) - pixel_values = pixel_values.permute(0, 2, 1, 3, 4) # ?

The issue was in tokenization_utils_base.py line 1417: ```python self.model_input_names = kwargs.pop("model_input_names", self.model_input_names) ``` When no model_input_names is passed in kwargs, it would use the class attribute directly (self.model_input_names), creating a reference to the shared list instead of creating a new list for the instance.

This causes a GPU-CPU synchronization that adds ~2-3ms per token, significantly impacting generation latency. This PR adds a context variable `_attention_mask_all_true` that is set at the start of generation based on the initial attention_mask. If the mask is all-True (no padding), the context variable allows subsequent calls to skip the expensive `.all()` check, since during generation we only append ones to the mask. This reduces `.all()` calls from N+1 to 1 for N generated tokens (e.g., from 201 to 1 for 200 tokens). ๐Ÿค– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- src/transformers/generation/utils.py | 28 ++++++++++++++++++---------- src/transformers/masking_utils.py | 14 +++++++++++++- 2 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/transformers/generation/utils.py b/src/transformers/generation/utils.py index cf9497d2a1f1..1f7a81575530 100644 --- a/src/transformers/generation/utils.py +++ b/src/transformers/generation/utils.py @@ -41,7 +41,7 @@ ) from ..integrations.deepspeed import is_deepspeed_zero3_enabled from ..integrations.fsdp import is_fsdp_managed_module -from ..masking_utils import create_masks_for_generate +from ..masking_utils import _attention_mask_all_true, create_masks_for_generate from ..pytorch_utils import isin_mps_friendly from ..tokenization_python import ExtensionsTrie from ..utils import ( @@ -2645,15 +2645,23 @@ def generate( model_kwargs["use_cache"] = generation_config.use_cache # 9.

+The VideoPrism model was proposed in the paper [VideoPrism: A Foundational Visual Encoder for Video Understanding](https://huggingface.co/papers/2402.13217) by Google DeepMind ([blog post](https://research.google/blog/videoprism-a-foundational-visual-encoder-for-video-understanding/)). -The abstract from the paper is the following: - -** +VideoPrism is a general-purpose video encoder that tackles diverse video understanding tasks with a single frozen model. The model is pretrained on a large-scale heterogeneous corpus containing 36M high-quality video-caption pairs and 582M video clips with noisy parallel text (e.g., ASR transcripts). The pretraining approach improves upon masked autoencoding through global-local distillation of semantic video embeddings and a token shuffling scheme, enabling the model to focus primarily on the video modality while leveraging text associated with videos. VideoPrism achieves state-of-the-art performance on 31 out of 33 video understanding benchmarks across four broad task groups, from web video question answering to computer vision for science. Tips: - +- VideoPrism uses a factorized spatio-temporal encoder architecture, processing videos through separate spatial and temporal transformers. +- The model supports video-text contrastive learning through `VideoPrismClipModel`, which combines a video encoder and a text encoder. +- For video classification tasks, use `VideoPrismForVideoClassification` which adds a classification head on top of the video encoder. +- The default input resolution is 288x288 pixels with 16 frames per video clip. +- The vision encoder can be used standalone via `VideoPrismVisionModel` for extracting video features. -This model was contributed by [INSERT YOUR HF USERNAME HERE](https://huggingface.co/). -The original code can be found [here](). +This model was contributed by [MHRDYN7](https://github.com/MHRDYN7) and reviewed by [qubvel](https://github.com/qubvel) & [zucchini-nlp](https://github.com/zucchini-nlp). +The original code can be found [here](https://github.com/google-deepmind/videoprism). ## VideoPrismVisionConfig @@ -44,7 +45,7 @@ The original code can be found [here]().

-## Overview +# VideoPrism The VideoPrism model was proposed in the paper [VideoPrism: A Foundational Visual Encoder for Video Understanding](https://huggingface.co/papers/2402.13217) by Google DeepMind ([blog post](https://research.google/blog/videoprism-a-foundational-visual-encoder-for-video-understanding/)). VideoPrism is a general-purpose video encoder that tackles diverse video understanding tasks with a single frozen model. The model is pretrained on a large-scale heterogeneous corpus containing 36M high-quality video-caption pairs and 582M video clips with noisy parallel text (e.g., ASR transcripts). The pretraining approach improves upon masked autoencoding through global-local distillation of semantic video embeddings and a token shuffling scheme, enabling the model to focus primarily on the video modality while leveraging text associated with videos. VideoPrism achieves state-of-the-art performance on 31 out of 33 video understanding benchmarks across four broad task groups, from web video question answering to computer vision for science. +

+ +You can find all original VideoPrism checkpoints under the [VideoPrism](https://huggingface.co/collections/google/videoprism) collection. + Tips: - VideoPrism uses a factorized spatio-temporal encoder architecture, processing videos through separate spatial and temporal transformers. -- The model supports video-text contrastive learning through `VideoPrismClipModel`, which combines a video encoder and a text encoder. -- For video classification tasks, use `VideoPrismForVideoClassification` which adds a classification head on top of the video encoder. -- The default input resolution is 288x288 pixels with 16 frames per video clip. -- The vision encoder can be used standalone via `VideoPrismVisionModel` for extracting video features. +- The model supports video-text contrastive learning through `VideoPrismClipModel`, which combines a video encoder and a text encoder. `VideoPrismConfig` must be used with this model. +- For video classification tasks, use `VideoPrismForVideoClassification` which adds a classification head on top of the video encoder. `VideoPrismVisionConfig` must be used with this model. +- The vision encoder can be used standalone via `VideoPrismVisionModel` for extracting video features. `VideoPrismVisionConfig` must be used with this model. +- The default input resolution is 288x288 pixels with 16 frames per video clip for the base models and 8 frames for the large models. Set interpolate_pos_encoding=True to use the models with custom resolution and frames per clip. This model was contributed by [MHRDYN7](https://github.com/MHRDYN7) and reviewed by [qubvel](https://github.com/qubvel) & [zucchini-nlp](https://github.com/zucchini-nlp).

The tokens_per_expert distribution (f_i) was summing to K instead of 1, while router_prob_per_expert (P_i) sums to 1, making the loss calculation incorrect. According to DeepSeek-MoE and megablocks implementations, f_i should be normalized by K so that both distributions represent the same scale: Before: sum(f_i) = K, sum(P_i) = 1 After: sum(f_i) = 1, sum(P_i) = 1 This ensures the load balancing loss correctly penalizes unbalanced routing when using top-k routing with k > 1.

Compute batch_size/seq_length from inputs_embeds - Initialize cache_position when absent - Build 3D position_ids from cache_position - Compute rope_deltas once during prefill - Reuse rope_deltas for subsequent decode steps Removes legacy attention_mask-dependent branch that was incompatible with static cache generation. Ensures correct RoPE offsets for multimodal inputs under both dynamic and static cache modes. --- .../models/qwen3_asr/modeling_qwen3_asr.py | 155 +++++++++++------ .../models/qwen3_asr/modular_qwen3_asr.py | 161 ++++++++++++------ 2 files changed, 212 insertions(+), 104 deletions(-) diff --git a/src/transformers/models/qwen3_asr/modeling_qwen3_asr.py b/src/transformers/models/qwen3_asr/modeling_qwen3_asr.py index e02074ee7403..3dffa684591b 100644 --- a/src/transformers/models/qwen3_asr/modeling_qwen3_asr.py +++ b/src/transformers/models/qwen3_asr/modeling_qwen3_asr.py @@ -295,10 +295,14 @@ def _prepare_4d_causal_attention_mask_with_cache_position( sequence_length: int, target_length: int, dtype: torch.dtype, - device: torch.device, - min_dtype: float, + # device: torch.device, + # min_dtype: float, cache_position: torch.Tensor, batch_size: int, + config=None, + past_key_values=None, + device: torch.device = None, + min_dtype: float = None, ): """ Creates a causal 4D mask of shape `(batch_size, 1, query_length, key_value_length)` from a 2D mask of shape @@ -322,6 +326,10 @@ def _prepare_4d_causal_attention_mask_with_cache_position( batch_size (`torch.Tensor`): Batch size.

The MetalConfig quantization backend can quantize standard checkpoints on-the-fly but cannot load pre-quantized MLX models. This commit fixes the five issues blocking that: 1. auto.py: Detect MLX affine quantization configs (mode=affine + bits + group_size) in AutoQuantizationConfig.from_dict() and map them to the Metal quantization method. 2. hub.py: Handle stale shard index files. MLX repos often copy model.safetensors.index.json from the original model, referencing non-existent shards. Add _rebuild_shard_index_from_repo() fallback that discovers actual safetensors files via HfApi and rebuilds the weight_map from their headers. 3. quantizer_metal.py: Add weight conversions for pre-quantized loading: - Rename MLX "biases" keys to "qbiases" (MetalLinear convention) - Dequantize embed_tokens back to float (nn.Embedding expects float) - Skip auto-exclusion of lm_head for pre-quantized checkpoints since MLX models typically quantize the output head too 4. conversion_mapping.py: Add Qwen3VL key prefix mappings for MLX checkpoint format (language_model.model.* -> model.language_model.*, language_model.lm_head.* -> lm_head.*, vision_tower.* -> model.visual.*) 5. metal_quantization.py: - Make MetalDequantize use source_patterns from kwargs as dict keys for flexibility with pattern-specific converters - Add _load_from_state_dict fallback for biases->qbiases rename - Add locally-compiled Metal shader fallback via torch.mps.compile_shader when the Hub kernel is unavailable or targets an incompatible MSL version --- src/transformers/conversion_mapping.py | 5 + .../integrations/metal_quantization.py | 196 ++++++++++++++++-- src/transformers/quantizers/auto.py | 15 +- .../quantizers/quantizer_metal.py | 25 ++- src/transformers/utils/hub.py | 106 ++++++++-- 5 files changed, 317 insertions(+), 30 deletions(-) diff --git a/src/transformers/conversion_mapping.py b/src/transformers/conversion_mapping.py index 3ef37bd0cfdf..f658d7a3e8c6 100755 --- a/src/transformers/conversion_mapping.py +++ b/src/transformers/conversion_mapping.py @@ -79,6 +79,11 @@ def _build_checkpoint_conversion_mapping(): "qwen3_5_text": [ WeightRenaming(source_patterns=r"^model.language_model", target_patterns="model"), ], + "qwen3_vl": [ + WeightRenaming(source_patterns=r"^language_model\.model\.", target_patterns="model.language_model."), + WeightRenaming(source_patterns=r"^language_model\.lm_head\.", target_patterns="lm_head."), + WeightRenaming(source_patterns=r"^vision_tower\.", target_patterns="model.visual."), + ], "t5gemma2": [ WeightRenaming(r"(? +using namespace metal;

Without this, these layernorms use the default eps (1e-5) instead of the config value (1e-6), causing precision errors vs vLLM/SGLang implementations. Edit applied to modular_deepseek_v3.py; generated modeling files (deepseek_v3, glm4_moe_lite, longcat_flash, youtu) updated via `make fix-repo`.

Score sorting: results are now always returned sorted by descending confidence score, consistent with ZeroShotObjectDetectionPipeline and ImageClassificationPipeline. 2. top_k parameter: allows users to cap the number of returned detections to the N highest-confidence results. 3. labels parameter: accepts a list of class-name strings; only detections whose label appears in the list are returned. This is a novel filtering capability with no prior equivalent in the standard detection pipeline. 4. box_format parameter: controls the coordinate format of the returned bounding boxes. Supported values: - 'xyxy' (default): {xmin, ymin, xmax, ymax} in pixels (backward compat) - 'xywh': {x_center, y_center, width, height} in pixels - 'normalized': {xmin, ymin, xmax, ymax} as floats in [0, 1] All new parameters are optional with safe defaults, preserving 100% backward compatibility. _get_bounding_box is extended to handle all three formats in one place. 8 new unit tests added covering: - top_k truncation - score sort order guarantee - label allowlist filtering (match and no-match) - all three box_format values - invalid box_format raises ValueError Fixes inconsistency where ObjectDetectionPipeline was the only vision pipeline without top_k or sorted outputs. --- .../pipelines/object_detection.py | 140 +++++++++++--- .../test_pipelines_object_detection.py | 171 ++++++++++++++++-- 2 files changed, 271 insertions(+), 40 deletions(-) diff --git a/src/transformers/pipelines/object_detection.py b/src/transformers/pipelines/object_detection.py index 0a4fba996d7d..68e61cf3664c 100644 --- a/src/transformers/pipelines/object_detection.py +++ b/src/transformers/pipelines/object_detection.py @@ -1,4 +1,4 @@ -from typing import TYPE_CHECKING, Any, Union, overload +from typing import TYPE_CHECKING, Any, Literal, Union, overload from ..utils import add_end_docstrings, is_torch_available, is_vision_available, logging, requires_backends from .base import Pipeline, build_pipeline_init_args @@ -35,9 +35,9 @@ class ObjectDetectionPipeline(Pipeline): >>> detector = pipeline(model="facebook/detr-resnet-50") >>> detector("https://huggingface.co/datasets/Narsil/image_dummy/raw/main/parrots.png") - [{'score': 0.997, 'label': 'bird', 'box': {'xmin': 69, 'ymin': 171, 'xmax': 396, 'ymax': 507}}, {'score': 0.999, 'label': 'bird', 'box': {'xmin': 398, 'ymin': 105, 'xmax': 767, 'ymax': 507}}] + [{'score': 0.999, 'label': 'bird', 'box': {'xmin': 398, 'ymin': 105, 'xmax': 767, 'ymax': 507}}, {'score': 0.997, 'label': 'bird', 'box': {'xmin': 69, 'ymin': 171, 'xmax': 396, 'ymax': 507}}] - >>> # x, y are expressed relative to the top left hand corner. + >>> # Results are sorted by score descending. x, y are expressed relative to the top left hand corner. ``` Learn more about the basics of using a pipeline in the [pipeline tutorial](../pipeline_tutorial) @@ -65,9 +65,17 @@ def _sanitize_parameters(self, **kwargs): preprocess_params = {} if "timeout" in kwargs: preprocess_params["timeout"] = kwargs["timeout"] + postprocess_kwargs = {} if "threshold" in kwargs: postprocess_kwargs["threshold"] = kwargs["threshold"] + if "top_k" in kwargs: + postprocess_kwargs["top_k"] = kwargs["top_k"] + if "labels" in kwargs: + postprocess_kwargs["labels"] = kwargs["labels"] + if "box_format" in kwargs: + postprocess_kwargs["box_format"] = kwargs["box_format"] + return preprocess_params, {}, postprocess_kwargs @overload @@ -94,7 +102,21 @@ def __call__(self, *args, **kwargs) -> list[dict[str, Any]] | list[list[dict[str same format: all as HTTP(S) links, all as local paths, or all as PIL images. threshold (`float`, *optional*, defaults to 0.5): The probability necessary to make a prediction. - timeout (`float`, *optional*, defaults to None): + top_k (`int`, *optional*, defaults to `None`): + The number of top detections to return, sorted by descending confidence score.

      + +## Overview + +**Penguin-VL** is a compact vision-language model family built to study how far multimodal efficiency can be pushed by redesigning the **vision encoder**, rather than only scaling data or model size. + +Most modern VLMs rely on vision encoders pretrained with large-scale **contrastive objectives** such as CLIP or SigLIP. Penguin-VL argues that this setup can be suboptimal for multimodal reasoning because contrastive learning favors coarse category-level invariances over the fine-grained signals needed for **OCR, document understanding, dense captioning, and complex reasoning**. Instead, Penguin-VL introduces **Penguin-Encoder**, a vision encoder **initialized from a text-only LLM**, so the visual backbone starts closer to the language model representation space and learns more data-efficiently. + + + PenguinVL architecture.

Changes in both modular_colqwen2.py and modeling_colqwen2.py: - Add TransformersKwargs to imports; add Unpack import in modeling file - Remove explicit output_attentions, output_hidden_states, and return_dict params from ColQwen2ForRetrieval.forward() -- these are now captured via **kwargs: Unpack[TransformersKwargs] - Remove manual config-resolution boilerplate for those three flags - Pop output_hidden_states from kwargs and resolve from config as fallback (matching the pattern established in ColPali parent) - Always pass output_hidden_states=True to self.vlm.model() so hidden states are always collected internally; only returned to the caller when explicitly requested - Spread **kwargs into self.vlm.model() so output_attentions and other flags flow through naturally to the underlying Qwen2VL model, which already handles output capturing via @capture_outputs and @merge_with_config_defaults The @can_return_tuple decorator (already present) continues to handle the return_dict=False tuple-conversion path.

Since `masked_scatter` natively supports broadcasting, this expansion materializes a large boolean tensor unnecessarily. Changes: - Remove `.expand_as(inputs_embeds)` from mask creation, keeping masks as (B, S, 1) and relying on `masked_scatter`/`torch.where` broadcasting - Replace `inputs_embeds[mask].numel() == features.numel()` validation with equivalent arithmetic `n_tokens * hidden_dim == features.numel()`, which avoids data-dependent boolean indexing and is more torch.compile-friendly --- .../modeling_new_task_model.py | 8 +++----- src/transformers/integrations/tensor_parallel.py | 4 ++-- src/transformers/models/aria/modeling_aria.py | 4 ++-- .../models/aya_vision/modeling_aya_vision.py | 4 ++-- .../models/blip_2/modeling_blip_2.py | 6 +++--- .../models/chameleon/modeling_chameleon.py | 4 ++-- .../cohere2_vision/modeling_cohere2_vision.py | 4 ++-- .../models/colqwen2/modeling_colqwen2.py | 4 +--- .../models/colqwen2/modular_colqwen2.py | 4 +--- .../models/deepseek_vl/modeling_deepseek_vl.py | 4 ++-- .../modeling_deepseek_vl_hybrid.py | 6 +++--- .../modular_deepseek_vl_hybrid.py | 2 +- src/transformers/models/emu3/modeling_emu3.py | 4 ++-- src/transformers/models/emu3/modular_emu3.py | 4 ++-- .../ernie4_5_vl_moe/modeling_ernie4_5_vl_moe.py | 8 ++++---- .../models/fast_vlm/modeling_fast_vlm.py | 4 ++-- .../models/florence2/modeling_florence2.py | 4 ++-- src/transformers/models/fuyu/modeling_fuyu.py | 4 ++-- .../models/gemma3/modeling_gemma3.py | 4 ++-- .../models/gemma3n/modeling_gemma3n.py | 12 ++++++------ .../models/gemma3n/modular_gemma3n.py | 12 ++++++------ .../models/glm46v/modeling_glm46v.py | 8 ++++---- src/transformers/models/glm4v/modeling_glm4v.py | 8 ++++---- src/transformers/models/glm4v/modular_glm4v.py | 8 ++++---- .../models/glm4v_moe/modeling_glm4v_moe.py | 8 ++++---- .../models/glm_ocr/modeling_glm_ocr.py | 8 ++++---- .../models/got_ocr2/modeling_got_ocr2.py | 4 ++-- .../higgs_audio_v2/modeling_higgs_audio_v2.py | 2 +- .../higgs_audio_v2/modular_higgs_audio_v2.py | 2 +- .../models/idefics2/modeling_idefics2.py | 2 +- .../models/idefics3/modeling_idefics3.py | 2 +- .../models/instructblip/modeling_instructblip.py | 4 ++-- .../modeling_instructblipvideo.py | 6 +++--- .../modular_instructblipvideo.py | 4 ++-- .../models/internvl/modeling_internvl.py | 4 ++-- src/transformers/models/janus/modeling_janus.py | 4 ++-- src/transformers/models/janus/modular_janus.py | 4 ++-- .../models/lfm2_vl/modeling_lfm2_vl.py | 4 ++-- .../models/lfm2_vl/modular_lfm2_vl.py | 4 ++-- .../models/lighton_ocr/modeling_lighton_ocr.py | 4 ++-- .../models/llama4/modeling_llama4.py | 4 ++-- src/transformers/models/llava/modeling_llava.py | 4 ++-- .../models/llava_next/modeling_llava_next.py | 4 ++-- .../modeling_llava_next_video.py | 8 ++++---- .../llava_next_video/modular_llava_next_video.py | 8 ++++---- .../llava_onevision/modeling_llava_onevision.py | 8 ++++---- .../models/mistral3/modeling_mistral3.py | 4 ++-- src/transformers/models/ovis2/modeling_ovis2.py | 10 +++------- src/transformers/models/ovis2/modular_ovis2.py | 6 +----- .../models/paddleocr_vl/modeling_paddleocr_vl.py | 4 ++-- .../models/paddleocr_vl/modular_paddleocr_vl.py | 4 ++-- .../models/paligemma/modeling_paligemma.py | 10 ++++------ .../perception_lm/modeling_perception_lm.py | 8 ++++---- .../perception_lm/modular_perception_lm.py | 8 ++++---- src/transformers/models/pi0/modeling_pi0.py | 5 +---- src/transformers/models/pi0/modular_pi0.py | 5 +---- .../models/qwen2_5_omni/modeling_qwen2_5_omni.py | 16 ++++++++-------- .../models/qwen2_5_omni/modular_qwen2_5_omni.py | 16 ++++++++-------- .../models/qwen2_5_vl/modeling_qwen2_5_vl.py | 8 ++++---- .../models/qwen2_audio/modeling_qwen2_audio.py | 2 +- .../models/qwen2_vl/modeling_qwen2_vl.py | 8 ++++---- .../models/qwen3_5/modeling_qwen3_5.py | 8 ++++---- .../models/qwen3_5_moe/modeling_qwen3_5_moe.py | 8 ++++---- .../qwen3_omni_moe/modeling_qwen3_omni_moe.py | 10 +++++----- .../models/qwen3_vl/modeling_qwen3_vl.py | 8 ++++---- .../models/qwen3_vl_moe/modeling_qwen3_vl_moe.py | 8 ++++---- .../models/t5gemma2/modeling_t5gemma2.py | 4 ++-- .../models/t5gemma2/modular_t5gemma2.py | 4 ++-- .../video_llama_3/modeling_video_llama_3.py | 8 ++++---- .../models/video_llava/modeling_video_llava.py | 8 ++++---- .../models/vipllava/modeling_vipllava.py | 4 ++-- 71 files changed, 199 insertions(+), 221 deletions(-) diff --git a/examples/modular-transformers/modeling_new_task_model.py b/examples/modular-transformers/modeling_new_task_model.py index 6e739fa0dbf4..a53755d1e2f0 100644 --- a/examples/modular-transformers/modeling_new_task_model.py +++ b/examples/modular-transformers/modeling_new_task_model.py @@ -174,9 +174,7 @@ def create_causal_mask_mapping( # running generation with custom loop.

[PATCH 0724/1308] fix(molmo2): fix CI failures - remove einops, add @strict, fix base_model_prefix - Replace einops.rearrange with native numpy reshape+transpose+reshape - Add @strict decorator to all 4 config classes (Molmo2VitConfig, Molmo2AdapterConfig, Molmo2TextConfig, Molmo2Config) to satisfy TRF010 - Set Molmo2Model.base_model_prefix = "model" (was empty, violating TRF002) - Fix image_mean/image_std mutable shared list (copy constants on init) - Fix test_image_processing: use image_processing_class instead of image_processor_list; skip CHW torch and 4-channel unsupported

DeepSeek-OCR-2 model was proposed in [Visual Causal Flow: A Novel Approach to OCR-Specialized Vision-Language Models](https://huggingface.co/papers/2601.20552) by the DeepSeek team. DeepSeek-OCR-2 is an OCR-specialized vision-language model built on a distinctive architecture: a SAM ViT-B vision encoder feeds into a Qwen2 hybrid attention encoder, which is connected through an MLP projector to a DeepSeek-V2 Mixture-of-Experts (MoE) language model. A key feature of the model is its hybrid attention mechanism, which applies bidirectional attention over image tokens and causal attention over query tokens, enabling efficient and accurate document understanding. diff --git a/src/transformers/models/deepseek_ocr2/configuration_deepseek_ocr2.py b/src/transformers/models/deepseek_ocr2/configuration_deepseek_ocr2.py index f567590a12ab..6c10b307c750 100644 --- a/src/transformers/models/deepseek_ocr2/configuration_deepseek_ocr2.py +++ b/src/transformers/models/deepseek_ocr2/configuration_deepseek_ocr2.py @@ -146,12 +146,6 @@ def __post_init__(self, **kwargs): @strict(accept_kwargs=True) class DeepseekOcr2TextConfig(PreTrainedConfig): r""" -

It provides transformations such as resizing, normalization, and conversion into PyTorch. Along ith transformations the `VideoProcessor` class handles video decoding from local paths or URLs (requires [`torchcodec`](https://pypi.org/project/torchcodec/)) and frame sampling according to model-specific strategies. The video processor extends the functionality of image processors by allowing Vision Large Language Models (VLMs) to handle videos with a distinct set of arguments compared to images. It serves as the bridge between raw video data and the model, ensuring that input features are optimized for the VLM. diff --git a/docs/source/en/model_doc/videoprism.md b/docs/source/en/model_doc/videoprism.md index 23107ec304d8..05cbb3d86195 100644 --- a/docs/source/en/model_doc/videoprism.md +++ b/docs/source/en/model_doc/videoprism.md @@ -1,4 +1,4 @@ - -*This model was released on 2024-02-20 and added to Hugging Face Transformers on 2026-04-01.* +*This model was released on 2024-02-20 and added to Hugging Face Transformers on 2026-04-03.*

Inheriting TimesFM's first-patch normalization gives the same result mathematically (per-patch norm + denorm + stream norm + denorm is an identity over the extra factors), but sends inputs to the transformer in a different scale than what the checkpoint was trained on, and is less efficient. This replaces the per-first-patch `_forward_transform` step with a single stream-level `_normalize_with_pad` (matching `PatchedTSMultiResolutionDecoder` in the reference), returns stream stats as `CtsmOutput.loc/scale`, and lets `CtsmModelForPrediction._decode_step` denormalize in a single pass. Verified against the 250M hub checkpoint on the reference notebook datasets: cpu_util MAE model=2.11 naive_last=3.36 (~37% better) server_responsetime MAE model=0.65 naive_last=2.05 (~3x better) internet_traffic MAE model=805 naive_last=4071 (~5x better) Quantile predictions stay monotone; 95 tests still pass. --- src/transformers/models/ctsm/modeling_ctsm.py | 72 +++++++++++------- src/transformers/models/ctsm/modular_ctsm.py | 74 ++++++++++++------- 2 files changed, 96 insertions(+), 50 deletions(-) diff --git a/src/transformers/models/ctsm/modeling_ctsm.py b/src/transformers/models/ctsm/modeling_ctsm.py index 411b6dca5c91..fd1af0d4e777 100644 --- a/src/transformers/models/ctsm/modeling_ctsm.py +++ b/src/transformers/models/ctsm/modeling_ctsm.py @@ -43,12 +43,16 @@ @auto_docstring class CtsmOutput(BaseModelOutput): r""" + loc (`torch.Tensor` of shape `(batch_size,)`): + Stream-level mean used to normalize the fine-resolution context, reused to rescale the final forecast. + scale (`torch.Tensor` of shape `(batch_size,)`): + Stream-level standard deviation of the fine-resolution context. loc_coarse (`torch.Tensor` of shape `(batch_size,)`): - Per-stream mean used to normalize the coarse-resolution context. + Stream-level mean used to normalize the coarse-resolution context. scale_coarse (`torch.Tensor` of shape `(batch_size,)`): - Per-stream standard deviation used to normalize the coarse-resolution context. + Stream-level standard deviation of the coarse-resolution context. num_coarse_patches (`int`): - Number of patches in the coarse-resolution block of the concatenated sequence. + Number of patches (including the optional special token) preceding the fine-resolution block. num_fine_patches (`int`): Number of patches in the fine-resolution block of the concatenated sequence.

Its central idea is a **multi-resolution context**: instead of consuming a single-scale history, each forecast conditions on two aligned streams โ€” a coarse low-frequency stream (e.g. 512 hourly points) and a fine high-frequency stream (e.g. 512 minutely points), with the resolution ratio fixed to 60. A learnable **special token** separates the two streams and learned **resolution embeddings** are added to the token stream to distinguish them. The coarse stream lets the model see week-over-week structure without giving up fine-grained recent detail; as the paper puts it, "more complex multiresolution architectures would require a context length of 30,720 (30 times as long as ours) to cover the same time range." -## Usage example +The abstract from the paper is the following: + +*We introduce the Cisco Time Series Model, a univariate zero-shot forecaster. This time series foundation model is the result of a general architectural innovation to a time series model enabling it to accept multiresolution input, applied to a popular decoder-only time series model (TimesFM). The resulting multiresolution decoder-only model is trained on over 300B unique data points, with more than half coming from the observability domain. Quantitative and qualitative evaluations demonstrate that the resulting model achieves superior performance on observability datasets while retaining very similar performance on a standard general-purpose forecasting benchmark (GIFT-Eval), and suggest that the multiresolution structure enables the model to make more accurate predictions on long context input.* + +### Architecture + +The backbone follows TimesFM 2.0: patching (patch length 32) + a residual-block input tokenizer + decoder-only transformer layers with per-dimension learnable query scaling + a residual-block horizon head. CTSM adds, on top: + +- A **special token** inserted between the coarse and fine patch streams, so the input is `[coarseโ‚, โ€ฆ, coarseโ‚โ‚†, SPECIAL, fineโ‚, โ€ฆ, fineโ‚โ‚†]`. +- **Resolution embeddings** (3-way: coarse / special / fine) added to each token before the transformer stack. +- **Stream-level normalization**: each stream is standardized independently over its non-padded context, and the fine-stream statistics are used to rescale the forecast. +- A **frequency embedding** inherited from TimesFM, added to every token. + +The 250M **CTSM 1.0** release checkpoint additionally introduces (over the 500M `1.0-preview` described in the paper): + +- **Rotary position embeddings (RoPE)** applied to query/key inside attention. +- **Bidirectional attention over the coarse block** โ€” tokens in the coarse segment attend both ways within that segment, while the fine segment remains causal. +- **15-quantile prediction** (levels 0.01โ€“0.99) instead of 9. +- **Short-context training** (1/3 of training samples drawn with `|fine| โˆˆ [10, 511]`) for better robustness when less history is available. +- Trained from scratch (not continued pre-training from TimesFM 2.0) on ~2ร— more internal observability data. + +### Inference + +For horizons longer than `config.horizon_length` (128 steps), [`CtsmModelForPrediction`] runs an autoregressive multi-resolution decode loop: each step produces 128 fine-resolution predictions, the mean forecast is appended to the fine context, and every `agg_factor=60` new fine samples are mean-aggregated into a new coarse point. There is no KV cache โ€” the coarse block's bidirectional attention and the per-step stream renormalization make the standard append-only cache unsuitable, matching both the original reference implementation and the other time-series forecasters in `transformers`. + +The checkpoint can be found at [`cisco-ai/cisco-time-series-model-1.0`](https://huggingface.co/cisco-ai/cisco-time-series-model-1.0).

For T5 (and any model using relative position bias scaled by key_length), omitting this mask causes the bias to be computed over the full padded sequence length rather than the real encoder length, producing ~20ร— logit scale errors and wrong greedy-decoding outputs. 2. `Seq2SeqLMExportableModule._export_decoder` marked `encoder_hidden_states` dim-1 as dynamic (`encoder_hidden_seq_length`). With transformers 5.0 the static KV-cache size is a compile-time constant; a symbolic encoder dim creates a shape conflict during `torch.export` for models like T5 that slice the cross-attention causal mask against the cache size. Fix: - Add optional `encoder_attention_mask` parameter to `Seq2SeqLMDecoderExportableModuleWithStaticCache.forward` and thread it through to `self.decoder(...)`. - Remove the dynamic encoder dim in `_export_decoder`; callers are expected to pad encoder inputs to `max_cache_len` (the static export shape). - Update `Seq2SeqLMExportableModule.export()` and `generate()` to build and pass the encoder attention mask automatically. --- src/transformers/integrations/executorch.py | 76 ++++++++++++++++----- 1 file changed, 59 insertions(+), 17 deletions(-) diff --git a/src/transformers/integrations/executorch.py b/src/transformers/integrations/executorch.py index 675a0ea5783a..40672ae785e0 100644 --- a/src/transformers/integrations/executorch.py +++ b/src/transformers/integrations/executorch.py @@ -889,7 +889,13 @@ def __init__(self, model, max_static_cache_length, batch_size): self.register_buffer(f"value_cache_{i}", layer.values, persistent=False) self.register_buffer(f"cumulative_length_{i}", layer.cumulative_length, persistent=False) - def forward(self, decoder_input_ids, encoder_hidden_states, cache_position): + def forward( + self, + decoder_input_ids: torch.Tensor, + encoder_hidden_states: torch.Tensor, + cache_position: torch.Tensor, + encoder_attention_mask: torch.Tensor | None = None, + ): # Start by resetting static cache (it's needed to be able to run several generations with the same exported program, # as otherwise it's mutated in-place indefinitely - we cannot call reset in-between the `generate` as the program was # already exported) @@ -900,6 +906,7 @@ def forward(self, decoder_input_ids, encoder_hidden_states, cache_position): outputs = self.decoder( input_ids=decoder_input_ids, encoder_hidden_states=encoder_hidden_states, + encoder_attention_mask=encoder_attention_mask, past_key_values=self.cache, use_cache=True, ) @@ -947,7 +954,7 @@ def _export_encoder(self, encoder_input_ids): return exported_encoder - def _export_decoder(self, decoder_input_ids, encoder_hidden_states, cache_position): + def _export_decoder(self, decoder_input_ids, encoder_hidden_states, cache_position, encoder_attention_mask=None): target_device = self.full_model.device wrapped_decoder = ( Seq2SeqLMDecoderExportableModuleWithStaticCache( @@ -963,27 +970,35 @@ def _export_decoder(self, decoder_input_ids, encoder_hidden_states, cache_positi decoder_input_ids = decoder_input_ids.to(target_device) encoder_hidden_states = encoder_hidden_states.to(target_device) cache_position = cache_position.to(target_device) - - # Define dynamic dimension for encoder output sequence length - encoder_seq_len_dim = torch.export.Dim("encoder_hidden_seq_length", max=self.max_hidden_seq_length) - - # Export the decoder + if encoder_attention_mask is not None: + encoder_attention_mask = encoder_attention_mask.to(target_device) + + # Export the decoder. + # encoder_hidden_states uses a static shape to avoid a symbolic-shape + # conflict with the static KV cache size during torch.export.

Step 2 then assumes that every findable import name also has an entry in importlib.metadata.packages_distributions(). That assumption does not hold. On Python 3.13 with ComfyUI setups (#45520), and in any environment where the import is resolvable via a non-pip source, packages_distributions() has no "flash_attn" key. Because the list comprehension is evaluated before the `in` operator, short-circuit evaluation of the outer `and` does not protect us - the KeyError fires during `transformers` import and takes down the whole process before any model is loaded. Swap the four raising subscripts for `.get(name, [])`. If the name is missing from the distribution map we simply conclude that the requested flash-attention flavour is not properly installed - which is the same answer is_flash_attn_*_available() would have returned anyway - instead of raising. The inner helper `_is_package_available` already wraps the same subscript in a try/except, so we are only making the outer call sites match that contract.

      + +## Overview + +Audio-Visual Flamingo (AVF) is a fully open audio-visual large language model for joint understanding and reasoning over +audio, images, and videos. In Transformers, AVF pairs a SigLIP vision tower with an AF-Whisper audio encoder and a +Qwen2.5-7B causal language model, with separate projectors for visual and audio features. + +For video plus audio inputs, AVF does not simply concatenate visual and sound features. Instead, it aligns synchronized +visual and audio chunks, interleaves them along the time axis, applies Constrained Rotary Time Embeddings (CRTE), and +then feeds the fused sequence to the language model. In the Transformers interface, the processor prepares the required +media placeholder spans and the model replaces those token positions with projected multimodal embeddings during the +forward pass. + +The model checkpoint is available at: [nvidia/audio-visual-flamingo-hf](https://huggingface.co/nvidia/audio-visual-flamingo-hf) + +Highlights: + +- Unified prompting across image, video, and audio inputs. +- Joint video plus audio understanding from a single container when `load_audio_in_video=True`. +- Dynamic-S2 visual preprocessing for high-resolution images and sampled video frames. +- Temporal audio-visual interleaving with CRTE before the Qwen2.5-7B backbone. +- Replace-in-place multimodal fusion through processor-prepared media spans and projected media embeddings. + +This model was contributed by [Lasha Koroshinadze](https://huggingface.co/lashahub) and [Eric Bezzam](https://huggingface.co/bezzam). + +### Paper + +Audio-Visual Flamingo: Open Audio-Visual Intelligence for Long and Complex Videos +S.

When `load_audio_in_video=True`, a `video` content item can contribute +both visual frames and audio features from the same container. + +## How the model works + +### Architecture + +* **Vision tower** + SigLIP encodes images and sampled video frames. AVF uses Dynamic-S2 preprocessing to preserve fine-grained detail in + high-resolution visual inputs while keeping the visual token sequence compact. + +* **Audio tower** + AVF uses AF-Whisper, the Audio Flamingo series' Whisper-based audio encoder. Audio is resampled to 16 kHz mono, + converted to 128-bin log-mel spectrograms, and encoded in non-overlapping 30-second windows for long-form audio. + +* **Multimodal projectors** + Two 2-layer MLP projectors map visual and audio encoder features into the shared language-model hidden size. + +* **Temporal interleaving + CRTE** + After projection, synchronized visual and audio chunks are interleaved along the time axis rather than naively + concatenated. AVF then applies Constrained Rotary Time Embeddings (CRTE) to the interleaved sequence so the language + model can preserve absolute temporal structure while attending across co-occurring visual and auditory events. + +* **Language model** + A decoder-only multimodal language model built on a Qwen2.5-7B text backbone. In the Transformers interface, the + processor expands the required media spans and the model replaces those token positions with projected multimodal + embeddings during the forward pass; subsequent decode steps reuse the language-model cache. + +### Processor-level alignment + +1. The processor loads images, sampled video frames, and audio waveforms from the chat-template content items. +2. For `video` inputs, it can also decode the container audio stream when `load_audio_in_video=True`, so a single + video item yields synchronized visual and audio features. +3.

It sets `module.dt_bias._no_reinit = True` after the copy, but the flag is never checked by either code path (only the Linear-bias branch reads it). On transformers>=5.0, `_init_weights` is triggered a second time after `from_pretrained()` has loaded the checkpoint (the post-load safety pass that initializes tensors staying on `meta`). For `NemotronHForCausalLM` that silently overwrites the checkpoint values for `dt_bias` and `out_proj.weight` with fresh random draws. The model then outputs repetitive stop-word streams like ` and and and and ,` for any input. Minimal repro with any Nemotron-H checkpoint: from transformers import AutoConfig, AutoModelForCausalLM from safetensors.torch import load_file import json, pathlib path = ".../NVIDIA-Nemotron-Cascade-2-30B-A3B-BF16" # or Nano cfg = AutoConfig.from_pretrained(path); cfg._attn_implementation='eager' m = AutoModelForCausalLM.from_pretrained(path, config=cfg, torch_dtype='bfloat16') idx = json.loads((pathlib.Path(path) / 'model.safetensors.index.json').read_text())['weight_map'] k = 'backbone.layers.0.mixer.dt_bias' on_disk = load_file(f'{path}/{idx[k]}')[k] in_mem = m.backbone.layers[0].mixer.dt_bias print((on_disk.float() - in_mem.float().cpu()).abs().max()) # ~26.8 This patch makes `_init_weights` honour `_no_reinit` on both `dt_bias` and `out_proj.weight` (the only two params that re-init unconditionally), and sets `_no_reinit = True` on `out_proj.weight` after the initial kaiming scale so a second pass is a no-op. Ordinary fresh-init training is unaffected; only the second invocation becomes idempotent.

      + +# Granite4Vision + +[Granite Vision 4.1](https://huggingface.co/ibm-granite/granite-vision-4.1-4b) is a vision-language model from IBM Research designed for enterprise-grade document data extraction. It specializes in chart extraction (Chart2CSV, Chart2Summary, Chart2Code), table extraction (JSON, HTML, OTSL), and semantic key-value pair extraction. + +The model builds on [LLaVA-NeXT](llava_next) with several architectural innovations: + +1. **SigLIP2 Vision Encoder** ([`google/siglip2-so400m-patch16-384`](https://huggingface.co/google/siglip2-so400m-patch16-384)): images are tiled into 384x384 patches. +2. **Window Q-Former Projectors**: compress visual features 4x using windowed cross-attention over 4x4 patch windows into 2x2 tokens. +3. **DeepStack Feature Injection** with 8 vision-to-LLM injection points: + - *LayerDeepstack*: features from 4 vision encoder depths are projected into different early LLM layers. + - *SpatialDeepstack*: deepest vision features are split into 4 spatial groups and injected at later LLM layers. +4. **Language Model**: [Granite 4.1](https://huggingface.co/ibm-granite/granite-4.1-4b-base) (4B params) with LoRA adapters (rank 256) across all self-attention and MLP layers. + +The model is delivered as a LoRA adapter on top of the base LLM, enabling single deployments to support both multimodal and text-only workloads. Total parameter count is ~4B. + +```bibtex +@misc{granite-vision-4.1-4b, + title={Granite Vision 4.1}, + author={IBM Granite Vision Team}, + year={2026}, + url={https://huggingface.co/ibm-granite/granite-vision-4.1-4b} +} +``` + +> [!TIP] +> This model was contributed by the [IBM Granite Vision Team](https://github.com/ibm-granite). + +The example below demonstrates how to generate text based on an image with [`Pipeline`] or the [`AutoModel`] class. + + + + + +```python +import torch +from transformers import pipeline + +pipe = pipeline( + task="image-text-to-text", + model="ibm-granite/granite-vision-4.1-4b", + device=0, + torch_dtype=torch.bfloat16, +) +messages = [ + { + "role": "user", + "content": [ + {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"}, + {"type": "text", "text": "Describe this image."}, + ], + } +] +pipe(text=messages, max_new_tokens=100, return_full_text=False) +``` + + + + + +```python +import torch +from transformers import AutoProcessor, AutoModelForImageTextToText + +model_id = "ibm-granite/granite-vision-4.1-4b" + +processor = AutoProcessor.from_pretrained(model_id) +model = AutoModelForImageTextToText.from_pretrained( + model_id, torch_dtype=torch.bfloat16, device_map="auto" +).eval() + +# Merge LoRA adapters for faster inference +model.merge_lora_adapters() + +conversation = [ + { + "role": "user", + "content": [ + {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"}, + {"type": "text", "text": "Describe this image."}, + ], + }, +] +inputs = processor.apply_chat_template( + conversation, + add_generation_prompt=True, + tokenize=True, + return_dict=True, + return_tensors="pt", +).to(model.device) + +output = model.generate(**inputs, max_new_tokens=100) +print(processor.decode(output[0], skip_special_tokens=True)) +``` + + + + + +Quantization reduces the memory burden of large models by representing the weights in a lower precision.

      + +## Overview + +Granite Speech Plus is a variant of [Granite Speech](./granite_speech) whose projector consumes the concatenation of +the encoder's final hidden states with an arbitrary subset of its intermediate hidden states (along the feature +dimension). The selected intermediate layers are controlled by the `encoder_hidden_layers` config field on +[`GraniteSpeechPlusConfig`]; when it is `None`, the model behaves identically to Granite Speech. When it is set, the +projector's `encoder_hidden_size` must equal `encoder_config.hidden_dim * (len(encoder_hidden_layers) + 1)`. + +The rest of the architecture โ€” speech encoder, query transformer projector, language model, and optional LoRA adapter +โ€” is inherited unchanged from Granite Speech. See the [Granite Speech documentation](./granite_speech) for usage +examples; the same [`GraniteSpeechProcessor`] and [`GraniteSpeechFeatureExtractor`] are used here. + +## GraniteSpeechPlusConfig + +[[autodoc]] GraniteSpeechPlusConfig + +## GraniteSpeechPlusEncoderConfig + +[[autodoc]] GraniteSpeechPlusEncoderConfig + +## GraniteSpeechPlusForConditionalGeneration + +[[autodoc]] GraniteSpeechPlusForConditionalGeneration + -

Fri, 24 Apr 2026 01:59:49 +0000 Subject: [PATCH 1027/1308] Switch to canonical _is_hf_initialized flag per review Per @Rocketknight1's review: replace the ad-hoc `_no_reinit` flag with the existing `_is_hf_initialized` flag that `from_pretrained` already sets on checkpoint-loaded parameters. Guard each Mamba2 init target (A_log / D / dt_bias) and the residual-scaled `out_proj.weight` independently, so parameters restored from a checkpoint survive any subsequent `_init_weights` pass. --- .../models/nemotron_h/modeling_nemotron_h.py | 51 +++++++++---------- .../models/nemotron_h/modular_nemotron_h.py | 51 +++++++++---------- 2 files changed, 46 insertions(+), 56 deletions(-) diff --git a/src/transformers/models/nemotron_h/modeling_nemotron_h.py b/src/transformers/models/nemotron_h/modeling_nemotron_h.py index 681f4c3bc0ae..ad9ffec6b11d 100644 --- a/src/transformers/models/nemotron_h/modeling_nemotron_h.py +++ b/src/transformers/models/nemotron_h/modeling_nemotron_h.py @@ -973,29 +973,27 @@ def _init_weights(self, module): """Initialize the weights.""" super()._init_weights(module) if isinstance(module, NemotronHMamba2Mixer): - # Respect _no_reinit: once a Mamba2 mixer has been initialised (or - # its params have been loaded from a checkpoint in a previous - # load cycle), skip re-initialisation.

MTP modules no longer live on DeepseekV3Model / Glm4MoeModel (no more layer-list extension or forward_mtp method); configs still expose num_nextn_predict_layers as metadata. - New transformers.generation.candidate_generators.MTPCandidateGenerator (nn.Module, implements CandidateGenerator) owns the MTP layers and introspects the base model's decoder + RMSNorm classes to build them. from_pretrained pulls MTP-specific keys out of the main checkpoint. - _mtp_decoding: use self.model(...) -> last_hidden_state + self.lm_head instead of forcing output_hidden_states=True. - Tests updated for the new architecture; all 9 MTP tests + 55 tests in the generation suite pass. --- .../candidate_generators/__init__.py | 4 + .../generation/candidate_generators/mtp.py | 269 ++++++++++++++++++ src/transformers/generation/utils.py | 119 ++++---- .../deepseek_v3/modeling_deepseek_v3.py | 108 +------ .../models/deepseek_v3/modular_deepseek_v3.py | 113 +------- .../models/glm4_moe/modeling_glm4_moe.py | 95 +------ .../models/glm4_moe/modular_glm4_moe.py | 99 +------ .../glm4_moe_lite/modeling_glm4_moe_lite.py | 89 +----- .../glm4v_moe/configuration_glm4v_moe.py | 1 -

String / list values are still accepted for backward compatibility but are translated into fsdp_config entries (and emit a deprecation warning). - fsdp_config now defaults to FSDP2 (version=2). FSDP1 usage still works but logs a deprecation warning (to be removed in v5.20). - New fsdp_config keys: auto_wrap_policy (default TRANSFORMER_BASED_WRAP), cpu_offload, state_dict_type (default FULL_STATE_DICT so trainer.save_model() produces an HF-compatible checkpoint out of the box). - FSDP1-only handling (forward_prefetch, backward_prefetch, use_orig_params, sync_module_states, and the string form of reshard_after_forward) is now isolated in a single branch for easy removal once v1 support is dropped. Legacy `fsdp` string/list parsing lives in a single _apply_legacy_fsdp_to_config helper for the same reason. - Trainer reads args.fsdp / args.fsdp_config guarded so that running without FSDP (or via `accelerate launch` with no transformers-side config) no longer crashes on None. - Docstring rewritten around fsdp_config; FSDP2-only keys surfaced, FSDP1-only keys (sync_module_states, use_orig_params, limit_all_gathers) dropped from the public docstring. Verified on the repro from PR #42521: TrainingArguments(fsdp=True, fsdp_config={"fsdp_version": 2, "reshard_after_forward": True}) now produces fsdp_version=2 and reshard_after_forward=True. --- src/transformers/trainer.py | 11 +- src/transformers/training_args.py | 371 +++++++++--------- .../test_trainer_distributed_fsdp.py | 26 +- 3 files changed, 202 insertions(+), 206 deletions(-) diff --git a/src/transformers/trainer.py b/src/transformers/trainer.py index f434d78d4040..4326f957dd63 100755 --- a/src/transformers/trainer.py +++ b/src/transformers/trainer.py @@ -447,13 +447,13 @@ def __init__( elif len(devices) == 1: self.is_model_parallel = self.args.device != torch.device(devices[0]) - self.is_fsdp_xla_enabled = args.fsdp_config["xla"] - if len(args.fsdp) > 0: + self.is_fsdp_xla_enabled = bool(args.fsdp) and args.fsdp_config.get("xla", False) + if args.fsdp: if self.is_deepspeed_enabled: raise ValueError( "Using --fsdp xxx together with --deepspeed is not possible, deactivate one of those flags." ) - if not args.fsdp_config["xla"] and args.parallel_mode != ParallelMode.DISTRIBUTED: + if not self.is_fsdp_xla_enabled and args.parallel_mode != ParallelMode.DISTRIBUTED: raise ValueError("Using fsdp only works in distributed training.") # Postpone switching model to cuda when MP, DeepSpeed, full bf16/fp16 eval, or FSDP @@ -598,7 +598,7 @@ def __init__( if getattr(self.model, "config", None) is not None: self.model.config.use_cache = self.args.use_cache - self.is_fsdp_xla_v2_enabled = args.fsdp_config.get("xla_fsdp_v2", False) + self.is_fsdp_xla_v2_enabled = bool(args.fsdp_config) and args.fsdp_config.get("xla_fsdp_v2", False) if self.is_fsdp_xla_v2_enabled: if not IS_XLA_FSDPV2_POST_2_2: raise ValueError("FSDPv2 requires `torch_xla` 2.2 or higher.") @@ -823,8 +823,9 @@ def create_accelerator_and_postprocess(self) -> None: # post accelerator creation setup if self.is_fsdp_enabled: fsdp_plugin = self.accelerator.state.fsdp_plugin + fsdp_config = self.args.fsdp_config or {} for param in ["limit_all_gathers", "activation_checkpointing"]: - setattr(fsdp_plugin, param, self.args.fsdp_config.get(param, getattr(fsdp_plugin, param))) + setattr(fsdp_plugin, param, fsdp_config.get(param, getattr(fsdp_plugin, param))) if fsdp_plugin.activation_checkpointing and self.args.gradient_checkpointing: raise ValueError( "The activation_checkpointing in FSDP config and the gradient_checkpointing in training arg " diff --git a/src/transformers/training_args.py b/src/transformers/training_args.py index 1a5924c723ab..ec483b9cbf07 100644 --- a/src/transformers/training_args.py +++ b/src/transformers/training_args.py @@ -649,75 +649,49 @@ class TrainingArguments: > FSDP (Fully Sharded Data Parallel) - fsdp (`bool`, `str` or list of [`~trainer_utils.FSDPOption`], *optional*, defaults to `None`): - Enable PyTorch Fully Sharded Data Parallel (FSDP) for distributed training.
