Command error:
  mkdir -p failed for path /home/mambauser/.cache/matplotlib: [Errno 13] Permission denied: '/home/mambauser/.cache/matplotlib'
  Matplotlib created a temporary cache directory at /tmp/matplotlib-h_trnkn8 because there was an issue with the default path (/home/mambauser/.cache/matplotlib); 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.
