thanks Steve but what is not clear to me is the following: in my udfs.py file I need to add the path to the python package library.
but should this be the path to pytz on the master computer or the path on the nodes? Indeed, the nodes also have pytz installed, and of course pytz in the nodes is installed in a different folder. is that an issue? Last, yes, pytz loads the timezones from a folder (zoneinfo) that is normally included in package-libs/pytz/zoneinfo thanks again!!!
