If you do not know the root cause of the problem / bug, and wish someone to help you, please include:

How To Reproduce the Issue

1. what changes you made (git diff) or what code you wrote No changes

2. what exact command you run pip install -e . In the detectron2 directory as mentioned in this blog https://gilberttanner.com/blog/detectron-2-object-detection-with-pytorch

3. what you observed (including the full logs):
