@ire-mide1 avoid using the main branch. Try to use a new branch for each issue or problem being solved.

@ire-mide1 - I'm guessing that you didn't mean to include the file deepforest/models/# Model.py in this PR. Can you remove it and update the PR?

Depending on your level of git experience it may be easiest to save your changes to tests/test_FasterRCNN.py outside of the repository, create a new branch from main, and then copy the saved file with your changes back into the repo. Once that's done we can give this will hopefully fix the failing tests and then we can take a look at the PR. Let me know if you have any questions as you go.
