MMDetection V2.23.0 Release

Highlights

• Support Mask2Former: Masked-attention Mask Transformer for Universal Image Segmentation
• Support EfficientNet: EfficientNet: Rethinking Model Scaling for Convolutional Neural Networks
• Support setting data root through environment variable MMDET_DATASETS, users don't have to modify the corresponding path in config files anymore.
• Find a good recipe for fine-tuning high precision ResNet backbone pre-trained by Torchvision.
