I tried setting up the python-sandpit, but I get the following error:
Matplotlib created a temporary config/cache directory at /tmp/matplotlib-8125qscx because the default path (/home/jobe00/.config/matplotlib) is not a writable directory; it is highly recommended to set the MPLCONFIGDIR environment variable to a writable directory, in particular to speed up the import of Matplotlib and to better support multiprocessing.
I found the error:
pip3 uninstall matplotlib
apt-get install python3-matplotlib
Solved the problem
