Unable to create new KR posts after reinstalling KR tools

[brian8128]

When I try to create a new knowledge repo post with the command knowledge_repo add ~/Downloads/NeutralLosses\ \(2\).ipynb -p NeutralLossesWithASimpleModel I get the following error. This happens to everyone on my team who installed the knowledge repo tools recently but doesn't happen to people who installed the knowledge repo tools a while ago.

INFO:knowledge_repo.repositories.gitrepository:Fetching updates to the knowledge repository...

INFO:knowledge_repo.repositories.gitrepository:Adding and committing 'NeutralLossesWithASimpleModel.kp' to local branch `NeutralLossesWithASimpleModel.kp`...

The above exception was the direct cause of the following exception:

Any luck to solve this issue? I am having the same problem but starting from zero and I can't get it working.

Thank you so much in advance.

It is due to gitpython version conflict, you can verify python package version from here. We should get all resolved in new version release.
