The koboldcpp.py script seems to import psutil. During my tests with Android, I noticed that library isn't included with a default python installation. A quick pip install psutil fixed this issue.

Thanks for bringing this up. Ah that's actually what I want to avoid - having external dependencies. I forgot my own dev system already had psutil installed but a fresh python install does not. I will have to remove psutil and replace it with some other function instead...
