When I install this add-on in the blender 3.3.21 (python 3.10), I run the script install_requirements.py as described in https://github.com/dfki-ric/phobos?tab=readme-ov-file#blender, it got the following error:

During handling of the above exception, another exception occurred:

Bug Fixed
It works after I import the importlib.util in the install_requirements.py, as followsing:

#!/usr/bin/python3

import importlib
import importlib.util
import subprocess
import sys

# other codes ...

Mybe you guys can help fix this issue. Thanks.
