How do i go about setting 'the MPLCONFIGDIR environment variable to a writable directory?'
Matplotlib created a temporary config/cache directory at /tmp/matplotlib-wvc1s_4i 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.
Thank you in advance
Given how slow all of the library imports are, I'm interested in trying to improve this even if it's "unnecessary"
Does anyone have any hints about the file system setup being used by repl.it, to figure out how to configure this?
