I am using the python 3.7.9 version. The dectron2 is not installed properly. command: docker exec -it 1ee02b74a599 /bin/bash root@1ee02b74a599:/app# pip install detectron2==0.2.1 -f https://dl.fbaipublicfiles.com/detectron2/wheels/cpu/torch1.4/index.html

the below issue occurred during the installation.
