I am also having same issue, I followed the steps very carefully, installed all mentioned dependecies yet I am unable to run the demo command "python3 demo.py --config-file configs/wearmask/darknet53.yaml --input ./datasets/wearmask/images/val2017 --opts MODEL.WEIGHTS output/model_0009999.pth". I looked into the folders and there is not output folder whatsoever.
