compatibility issue for pytorch 1.6 (#1658) @ly015MultilevelPixelData
(#1647) @liqikai9We are excited to announce the release of MMPose 1.0.0beta. MMPose 1.0.0beta is the first version of MMPose 1.x, a part of the OpenMMLab 2.0 projects. Built upon the new training engine.
Highlights
New engines. MMPose 1.x is based on MMEngine, which provides a general and powerful runner that allows more flexible customizations and significantly simplifies the entrypoints of high-level interfaces.
Unified interfaces. As a part of the OpenMMLab 2.0 projects, MMPose 1.x unifies and refactors the interfaces and internal logics of train, testing, datasets, models, evaluation, and visualization. All the OpenMMLab 2.0 projects share the same design in those interfaces and logics to allow the emergence of multi-task/modality algorithms.
More documentation and tutorials. We add a bunch of documentation and tutorials to help users get started more smoothly. Read it here.
Breaking Changes
In this release, we made lots of major refactoring and modifications. Please refer to the migration guide for details and migration instructions.
This release is meant to fix the compatibility with the latest mmcv v1.6.1

Breaking Changes
Refactor bbox processing in datasets and pipelines (#1311) @ly015, @Ben-Louis
The bbox format conversion (xywh to center-scale) and random translation are moved from the dataset to the pipeline. The comparison between new and old version is as below:
v0.26.0v0.25.0Dataset (e.g. TopDownCOCODataset)
... # Data sample only contains bbox rec.append({ 'bbox': obj['clean_bbox][:4], ... })
... # Convert bbox from xywh to center-scale center, scale = self._xywh2cs(*obj['clean_bbox'][:4]) # Data sample contains center and scale rec.append({ 'bbox': obj['clean_bbox][:4], 'center': center, 'scale': scale, ... })
(e.g. HRNet+COCO)
... train_pipeline = [ dict(type='LoadImageFromFile'), # Convert bbox from xywh to center-scale dict(type='TopDownGetBboxCenterScale', padding=1.25), # Randomly shift bbox center dict(type='TopDownRandomShiftBboxCenter', shift_factor=0.16, prob=0.3), ... ]
... train_pipeline = [ dict(type='LoadImageFromFile'), ... ]
_xywh2cs
of dataset base classes (e.g. Kpt2dSviewRgbImgTopDownDataset) will be deprecated in the future. Custom datasets will need modifications to move the bbox format conversion to pipelines.Highlights
