Great, this is very helpful.

As a follow up, I have two different venv directories with their own
activation script paths depending on how the virtual environment was
created. To accommodate both, I used:
source script 1 || source script 2

This is throwing an error though when script 2 should be run, it says: No
such file or directory, but the second script runs fine. How do I make this
silent so that it doesn't give an error?

Thanks, and sorry if this is considered an unrelated follow up.
