During development, I put in an error in my code. When running the code, the following error is thrown:

Multiple versions of MONAI may have been installed,
please uninstall existing packages (both monai and monai-weekly) and install a version again.

This is untrue. The problem isn't that I have multiple instances of MONAI installed, the problem is the error I've put in my code. I suspect there is a try statement somewhere that is being overly greedy.
