• How to reproduce the issue ?
By adding more images to face class in PeopleNet trainable model v2.6 as provided in the Jupyter notebook (DetectNet v2 sample)

Matplotlib created a temporary config/cache directory at /tmp/matplotlib-sbm_r37b 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.
