I've noticed that my quota capacity is almost fully used and I tried to trace the reason for this. It appears that I have a lot of packages installed that I have never used before. I.e. https://eu.pythonanywhere.com/user/wladzioo/files/usr/lib contains libraries like quantlib where a single file may weigh over 120mb.
15:35 /home $ du -sh 268M .
While the user panel shows '87% full – 892.4 MB of your 1.0 GB quota'
Why is that so?
Edit - selenium (chromium) tmp files where the reason for this.. after clearing /tmp/ now everything is back to normal
