Bugfix: `ROOT` module, HTCondor and remote modules For some reason, the execution environment (HTCondor workers) is not able to import the ‘ROOT’ Python module. Therefore, there were issues retrieving the number of events from *.root files. So: 1. Remove the last change and use Python 2 again 2. Remove the use of the `encoding` parameter for Python modules that run in HTCondor to allow Python 2 support again.
