runtime error

Exit code: 1. Reason: Matplotlib created a temporary cache directory at /tmp/matplotlib-nje06i66 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.
