Bugfix version.

We started to release pre-built wheels for multiple PyTorch versions:

CUDA	torch 1.5	torch 1.4
10.2	install `python -m pip install detectron2==0.1.3 -f \ https://dl.fbaipublicfiles.com/detectron2/wheels/cu102/torch1.5/index.html`

Incompatible changes about internal interface:

_init_{box,mask,keypoint}_head of StandardROIHeads was changed from instance method to class method.

v0.1.2

4 years ago

The pre-built wheels for this version have to be used with an official binary release of PyTorch 1.5.

Improvements:

Add semantic segmentation models to PointRend
Add examples to load a detectron2 model in C++
New models that reproduce Rethinking ImageNet Pre-training
Lots of new features in DensePose, see below
Fix a few bugs in rotated box computation

Incompatible changes:

When loading a checkpoint with resume_or_load(), training states like optimizer, start_iter will only be loaded when resume is True and the last checkpoint is found. This matches users’ expectations better
.output_size in custom box head is renamed to .output_shape
anchor_generator no longer duplicates the anchors for each image
feature_strides and feature_channels attributes are removed from ROIHeads. Use the input argument input_shape instead.

New in DensePose:

New evaluation metric (GPSm) that yields more reliable scores
Panoptic FPN head implementation following Panoptic Feature Pyramid Networks
DeepLabV3 head implementation following Rethinking Atrous Convolution for Semantic Image Segmentation
Models with confidence estimation: implementation of the paper Correlated Uncertainty for Learning Dense Correspondences from Noisy Labels
Contributions to the Model Zoo (for details please see the Model Zoo page):
- Panoptic FPN and tuned hyperparameters for the original fully convolutional DensePose head: the performance of the existing R50 and R101 baselines improved by +10 AP
- Panoptic FPN with DeepLabV3 head for DensePose: gives additional improvement of +2 AP
- Models with confidence estimation
Test time augmentations for DensePose (additional improvement of about +0.5 AP)

v0.1.1

4 years ago

Incompatible changes about head design:

Mask head and keypoint head now include logic for losses & inference. Custom heads should overwrite the feature computation by layers() method.
_forward_{box,mask,keypoint} methods of StandardROIHeads now accept dict of features.

This release is made to be compatible with such changes in projects (Mesh R-CNN, PointRend, etc)

Other additional features:

flops & parameters counting
Improve speed & RAM consumption of data loader

The pre-built wheels for this version have to be used with an official binary release of PyTorch 1.4.

4 years ago

Some major additional features since open source:

Add TensorMask and PointRend in projects/.
Support exporting models to caffe2 format.
detectron2.model_zoo APIs.
Support training with segmentation annotations in binary mask format.
Support evaluating COCO-style AP for datasets in custom format.

We start to provide pre-built binary wheels at https://dl.fbaipublicfiles.com/detectron2/wheels/index.html. The pre-built wheels for this version have to be used with an official binary release of PyTorch 1.4.
