Training

Single gpu for train:

CUDA_VISIBLE_DEVICES=0 python ./mmdetection/tools/train.py faster-rcnn_r50_afpn_1x_coco.py --work-dir ./weight/

Multiple gpus for train:

CUDA_VISIBLE_DEVICES=0,1 ./mmdetection/tools/dist_train.sh faster-rcnn_r50_afpn_1x_coco.py 2 --work-dir ./weight/

Train in pycharm: If you want to train in pycharm, you can run it in train.py.

see more details at mmdetection.

Testing

CUDA_VISIBLE_DEVICES=0 python ./mmdetection/tools/test.py faster-rcnn_r50_afpn_1x_coco.py <CHECKPOINT_FILE>

For example,

CUDA_VISIBLE_DEVICES=0 python ./mmdetection/tools/test.py faster-rcnn_r50_afpn_1x_coco.py ./weight/afpn_weight.pth

Test in pycharm: If you want to test in pycharm, you can run it in test.py.
