I don't understand why terminal responds with "Using PYTHONPATH=/Library/Frameworks/Python.framework/Versions:" to all commands to installed app

Apologies, because I feel this is going to be a really stupid question.

I have installed a framework call Monai Label via Terminal (https://docs.monai.io/projects/label/en/stable/installation.html).

Working my way through the prerequisites I have successfully updated Python to 3.8.9, as well as PyTorch. I have successfully installed MonaiLabel via pip install.

But now whenever I type in a command to MonaiLabel (like --version, or --help) terminal responds with Using PYTHONPATH=/Library/Frameworks/Python.framework/Versions:.

Thinking this meant I had to update the PYTHONPATH variable to the given path I updated the bash_profile via atom ~/.bash_profile. This file saved successfully, but that didn't seem to do anything.

I'm sorry all but this has left me very confused and I'm finding this one hard to research my way out of. Thanks in advance.

Mac OS 12.4, M1.
