Hello!
When I run my program it brokes and returns this:
Matplotlib created a temporary config/cache directory at /tmp/matplotlib-dlsn4s0n because the default path (/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.
Killed
exit status 137
Why is it?
