raise KeyError(key) from None KeyError: 'config_file'

[tcexeexe]

Hello~ l try to run the object-detector example,and l follow the instruction of https://github.com/heartexlabs/label-studio/blob/master/docs/source/tutorials/object-detector.md and download the checkpoint_file from MMDetection model zoo. l use the order to start the service label-studio-ml init coco-detector --from label_studio_ml/examples/mmdetection/mmdetection.py label-studio-ml start coco-detector --with config_file=./mmdetection/configs/faster_rcnn/faster_rcnn_r50_fpn_1x_coco.py checkpoint_file=/home/tcexeexe/dataDisk2/abel-studio-ml-backend/mmdetection/checkpoints/faster_rcnn_r50_fpn_1x_coco_20200130-047c8118.pth

My label setting is as follow but there is still an error occourred when l try to connect the label-studio-ml-backend

the error log from the backend is as follows:

where the problem might be?

Try to explicitly specify config_file as an environment variable:

config_file=/path/to/config/faster_rcnn_r50_fpn_1x.py label-studio-ml init coco-detector
config_file=/path/to/config/faster_rcnn_r50_fpn_1x.py label-studio-ml start coco-detector
