ROOT user required to report metrics

I used the package for custom container training with the AI training platform and it works if the user running the training process in the container is the root user. I feel a bit queasy about that and ideally would like to run the training as a less privileged user. However, the location where this package is writing the training-result quantities to appears to be only writeable by root.
It might be useful to allow this package to also work with non-root users.
