OSError: Failed reading a response

After this, it would not respond correctly until I pulled it out and put it back in.

Hey @michaelblyons, I hope someone else can help, I have no access/experience with macOS :/ What does this "Cellar" do?

[michaelblyons]

Cellar is a mnemonic for a beer-themed package manager (Homebrew) on MacOS. Macs do not come with Python 3 (although installing XCode also adds it).

It's conceivable that the pip I used put stuff in the wrong site-packages, but I think it's rather unlikely. Those point to the same place:

$ ls -l /usr/local/Cellar/python/3.7.6_1/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages
lrwxr-xr-x  1 me  mygroup  54 Feb 27 11:25 /usr/local/Cellar/python/3.7.6_1/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages -> ../../../../../../../../../lib/python3.7/site-packages

Works now. 🤷‍♂️
