v2.5.0

44a7ef2

MMDetection V2.5.0 Release

Highlights

Support new methods: YOLACT, CentripetalNet.
Add more documentations for easier and more clear usage.

Backwards Incompatible Changes

FP16 related methods are imported from mmcv instead of mmdet. (#3766, #3822)
Mixed precision training utils in mmdet.core.fp16 are moved to mmcv.runner, including force_fp32, auto_fp16, wrap_fp16_model, and Fp16OptimizerHook. A deprecation warning will be raised if users attempt to import those methods from mmdet.core.fp16, and will be finally removed in V2.8.0.

[0, N-1] represents foreground classes and N indicates background classes for all models. (#3221)
Before v2.5.0, the background label for RPN is 0, and N for other heads. Now the behavior is consistent for all models. Thus self.background_labels in dense_heads is removed and all heads use self.num_classes to indicate the class index of background labels.
This change has no effect on the pre-trained models in the v2.x model zoo, but will affect the training of all models with RPN heads. Two-stage detectors whose RPN head uses softmax will be affected because the order of categories is changed.

Only call get_subset_by_classes when test_mode=True and self.filter_empty_gt=True (#3695)
Function get_subset_by_classes in dataset is refactored and only filters out images when test_mode=True and self.filter_empty_gt=True.
In the original implementation, get_subset_by_classes is not related to the flag self.filter_empty_gt and will only be called when the classes is set during initialization no matter test_mode is True or False. This brings ambiguous behavior and potential bugs in many cases. After v2.5.0, if filter_empty_gt=False, no matter whether the classes are specified in a dataset, the dataset will use all the images in the annotations. If filter_empty_gt=True and test_mode=True, no matter whether the classes are specified, the dataset will call ``get_subset_by_classes` to check the images and filter out images containing no GT boxes. Therefore, the users should be responsible for the data filtering/cleaning process for the test dataset.

New Features

Test time augmentation for single stage detectors (#3844, #3638)
Support to show the name of experiments during training (#3764)
Add Shear, Rotate, Translate Augmentation (#3656, #3619, #3687)
Add image-only transformations including Constrast, Equalize, Color, and Brightness. (#3643)
Support YOLACT (#3456)
Support CentripetalNet (#3390)
Support PyTorch 1.6 in docker (#3905)

Bug Fixes

Fix the bug of using Focal Loss when there is num_pos is 0 (#3702)
Fix the label index mapping in dataset browser (#3708)

v2.4.0

039ad4d

MMDetection V2.4.0 Release

Highlights

Fix lots of issues/bugs and reorganize the trouble shooting page
Support new methods SABL, YOLOv3, and PAA Assign
Support Batch Inference
Start to publish mmdet package to PyPI since v2.3.0
Switch model zoo to download.openmmlab.com

Backwards Incompatible Changes

Support Batch Inference (#3564, #3686, #3705): Since v2.4.0, MMDetection could inference model with multiple images in a single GPU.
This change influences all the test APIs in MMDetection and downstream codebases. To help the users migrate their code, we use replace_ImageToTensor (#3686) to convert legacy test data pipelines during dataset initialization.
Support RandomFlip with horizontal/vertical/diagonal direction (#3608): Since v2.4.0, MMDetection supports horizontal/vertical/diagonal flip in the data augmentation. This influences bounding box, mask, and image transformations in data augmentation process and the process that will map those data back to the original format.
Migrate to use mmlvis and mmpycocotools for COCO and LVIS dataset (#3727). The APIs are fully compatible with the original lvis and pycocotools. Users need to uninstall the existing pycocotools and lvis packages in their environment first and install mmlvis & mmpycocotools.
