- The inference time is evaluated with a single 2080Ti GPU.
- We use the models pre-trained on ImageNet using torchvision. The ImageNet pre-trained ResNet-101 backbone is obtained from SparseR-CNN.
The codes are built on top of Detectron2, SparseR-CNN, and AdelaiDet.
- Python=3.8
- PyTorch=1.6.0, torchvision=0.7.0, cudatoolkit=10.1
- OpenCV for visualization
- Install the repository (we recommend to use Anaconda for installation.)
conda create -n ISTR python=3.8 -y
conda activate ISTR
conda install pytorch==1.6.0 torchvision==0.7.0 cudatoolkit=10.1 -c pytorch
or (conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch)
pip install opencv-python
pip install scipy
pip install shapely
git clone https://github.com/hujiecpp/ISTR.git
cd ISTR
python setup.py build develop
- Link coco dataset path
ln -s /coco_dataset_path/coco ./datasets
- Train ISTR (e.g., with ResNet50 backbone)
python projects/ISTR/train_net.py --num-gpus 4 --config-file projects/ISTR/configs/ISTR-R50-3x.yaml
- Evaluate ISTR (e.g., with ResNet50 backbone)
python projects/ISTR/train_net.py --num-gpus 4 --config-file projects/ISTR/configs/ISTR-R50-3x.yaml --eval-only MODEL.WEIGHTS ./output/model_final.pth
- Visualize the detection and segmentation results (e.g., with ResNet50 backbone)
python demo/demo.py --config-file projects/ISTR/configs/ISTR-R50-3x.yaml --input input1.jpg --output ./output --confidence-threshold 0.4 --opts MODEL.WEIGHTS ./output/model_final.pth
