Hello i've a problem when I try to start coco-detector:
`label-studio-ml start coco-detector --with config_file=label_studio_ml/examples/mmdetection/configs/faster_rcnn/faster_rcnn_r50_fpn_1x_coco.py checkpoint_file=label_studio_ml/examples/mmdetection/checkpoints/faster_rcnn_r50_fpn_1x_coco_20200130-047c8118.pth`

there is an error message:
python: can't open file './coco-detector/_wsgi.py': [Errno 2] No such file or directory

Can you help me please?
