Concerning the local repo modification, I’ve found that the instruction below adapted from the custom dataset tutorial 8:
!pip install -e "/content/gdrive/My Drive/Colab Notebooks/project_dir"/detectron2_repo

doesn’t  make the repo editable at all. No changes in files in the local repo take effect.
So if someone could point me a way to make the repo editable, it’ll help debug my issue.
I’ve searched around and found some other CLI but nothing works:
!cd "/content/gdrive/My Drive/Colab Notebooks/acdc"/detectron2_repo ; python setup.py develop

PS: I’m working on google colab! is that related to my inability to modify the repo ?
