Install

conda create -n zsi python=3.7 -y
conda activate zsi

conda install pytorch=1.1.0 torchvision=0.3.0 cudatoolkit=10.0 -c pytorch

pip install cython && pip --no-cache-dir install -r requirements.txt

python setup.py develop

Dataset prepare

• Download the train and test annotations files for zsi from annotations, put all json label file to

  data/coco/annotations/

• Download MSCOCO-2014 dataset and unzip the images it to path：

  data/coco/train2014/
  data/coco/val2014/

• Training:

  • 48/17 split:

      chmod +x tools/dist_train.sh
      ./tools/dist_train.sh configs/zsi/train/zero-shot-mask-rcnn-BARPN-bbox_mask_sync_bg_decoder.py 4

  • 65/15 split:

    chmod +x tools/dist_train.sh
    ./tools/dist_train.sh configs/zsi/train/zero-shot-mask-rcnn-BARPN-bbox_mask_sync_bg_65_15_decoder_notanh.py 4

• Inference & Evaluate:

  • ZSI task:

    • 48/17 split ZSI task:

      • download 48/17 ZSI model, put it in checkpoints/ZSI_48_17.pth

      • inference:

        chmod +x tools/dist_test.sh
        ./tools/dist_test.sh configs/zsi/48_17/test/zsi/zero-shot-mask-rcnn-BARPN-bbox_mask_sync_bg_decoder.py checkpoints/ZSI_48_17.pth 4 --json_out results/zsi_48_17.json

      • our results zsi_48_17.bbox.json and zsi_48_17.segm.json can also downloaded from zsi_48_17_reults.

      • evaluate:

        • for zsd performance

          python tools/zsi_coco_eval.py results/zsi_48_17.bbox.json --ann data/coco/annotations/instances_val2014_unseen_48_17.json

        • for zsi performance

    • 65/15 split ZSI task:

      • download 65/15 ZSI model, put it in checkpoints/ZSI_65_15.pth

      • inference:

        chmod +x tools/dist_test.sh
        ./toools/dist_test.sh configs/zsi/65_15/test/zsi/zero-shot-mask-rcnn-BARPN-bbox_mask_sync_bg_65_15_decoder_notanh.py checkpoints/ZSI_65_15.pth 4 --json_out results/zsi_65_15.json

      • our results zsi_65_15.bbox.json and zsi_65_15.segm.json can also downloaded from zsi_65_15_reults.

      • evaluate:

        • for zsd performance

  • GZSI task:

    • 48/17 split GZSI task:
      • use the same model file ZSI_48_17.pth in ZSI task
      • inference:

        chmod +x tools/dist_test.sh
        ./tools/dist_test.sh configs/zsi/48_17/test/gzsi/zero-shot-mask-rcnn-BARPN-bbox_mask_sync_bg_decoder_gzsi.py checkpoints/ZSI_48_17.pth 4 --json_out results/gzsi_48_17.json

      • our results gzsi_48_17.bbox.json and gzsi_48_17.segm.json can also downloaded from gzsi_48_17_results.
      • evaluate:
        • for gzsd
