Matlotlib error

Error when executing on STFC/PROD

mkdir -p failed for path /code/.config/matplotlib: [Errno 13] Permission denied: '/code/.config'

Matplotlib created a temporary cache directory at /tmp/matplotlib-4fgi82cu because there was an issue with the default path (/code/.config/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.

Even though Matplotlib seems to suggest it has worked round the problem no activity is seem after this.

Seems that we should set the MPLCONFIGDIR env variable and see what happens.
