  2. Build Non Maximum Suppression and ROI Align modules (modified from facebookresearch/maskrcnn-benchmark)

    1. Install

      $ python support/setup.py develop

    2. Uninstall

      $ python support/setup.py develop --uninstall

    3. Test

      $ python test/nms/test_nms.py

      • Result

  3. Install pycocotools for MS COCO 2017 dataset

    1. Clone and build COCO API

      $ git clone https://github.com/cocodataset/cocoapi
$ cd cocoapi/PythonAPI
$ make

      It's not necessary to be under project directory

    2. If an error with message pycocotools/_mask.c: No such file or directory has occurred, please install cython and try again

      $ pip install cython

    3. Copy pycocotools into project

      $ cp -R pycocotools /path/to/project
