[Kandinsky2.2 训练支持 · Issue #268 · PaddlePaddle/PaddleMIX](#268)

1 前200steps loss对齐结果:

  • decoder w/o LoRA:

decoder

  • prior w/o LoRA:

prior

  • decoder with LoRA:

decoder_lora

  • prior with LoRA:

prior_lora

  • decoder finue-tune 3k steps results(prompts: A robot pokemon, 4k photo):

robot-pokemon

2 其他修改

[ppdiffusers/models/attention_processor.py/LoRAAttnAddedKVProcessor.call] : axis = 1 -> axis = 2

修改原因:运行python train_text_to_image_decoder_lora.py使用LoRAAttnAddedKVProcessor出现concat拼接维度错误。

3 对齐说明

  • 关闭diffusers和ppdiffusers中dataloader中的shuffle,保证数据顺序一致;

  • 设置同一随机种子,并将在trainning loop中造成随机性的noise和timesteps改为由numpy生成统一随机结果(提交代码已删除该逻辑)。

4 存在问题

  • 在ppdiffusers中使用AutoPipelineForText2Image(args.pretrained_decoder_model_name_or_path)出现组件缺失:
     ValueError: Pipeline <class 'ppdiffusers.pipelines.kandinsky2_2.pipeline_kandinsky2_2_combined.KandinskyV22CombinedPipeline'> expected {'unet', 'prior_image_processor', 'prior_text_encoder', 'prior_image_encoder', 'movq', 'prior_prior', 'prior_scheduler', 'prior_tokenizer', 'scheduler'}, but only {'unet', 'movq', 'scheduler'} were passed.

    只能识别部分组件,无法像diffusers自动识别所有组件。故在提交代码中采取下策:在AutoPipelineForText2Image前逐个定义好后传入,不够简洁。目前原因未定,看到一个[diffusers的issue]([https://github.com/huggingface/diffusers/issues/5044)与该问题类似。

  • 使用pip install ppdiffusers=0.19.4 在下载prior的LoRA权重时会出现PriorTransformer找不到load_attn_procs, 无法使用pipeline.prior_prior.load_attn_procs(args.output_dir),但使用最新develop分支构建ppdiffusers安装包则不会出现这个问题。

----------期待回复与关于合入的建议, Thx :)------------------

感觉readme里面给使用例子不需要使用 AutoPipelineForText2Image,直接使用对应的pipleine加载就行了

我看整体上没有问题了,你这里能测一下所有的在paddle2.6.0 + 这个版本的ppdiffusers能跑通吗?

Hi, @JunnYu, 在paddle2.6.0下可以顺利跑通四个训练脚本。

同时解决了上述’无法使用pipeline.prior_prior.load_attn_procs()‘的问题,其原因为PriorTransformer需继承UNet2DConditionLoadersMixin,发现这个feature是在这个PR(Revert "【Hackathon 5th No.83】PaddleMIX ppdiffusers models模块功能升级同步HF)下被回滚了。

还有我这个CLA是咋回事来着~,已经签名了却仍然Pending。

这个CLA可以之后再看一下,确认一下你提交这个pr的跟你实际登录的是同一个github号,比如邮箱要一样啥的。
当前都没有问题了,可以合入了
