Get Started

1. install cvpods following the instructions

# Install cvpods
git clone https://github.com/Megvii-BaseDetection/cvpods
cd cvpods 
## build cvpods (requires GPU)
pip install -r requirements.txt
python setup.py build develop
## preprare data path
mkdir datasets
ln -s /path/to/your/coco/dataset datasets/coco

2. run the project

cd auto_assign.res50.fpn.coco.800size.1x

# train
pods_train --num-gpus 8

# test
pods_test --num-gpus 8
# test with provided weights
pods_test --num-gpus 8 MODEL.WEIGHTS /path/to/your/model.pth
