When I tried installing gdx2py from https://github.com/ererkka/GDX2py, I then got the follow error when trying to load a dataframe

Traceback (most recent call last):

This is not the same gdx2py. The one I am referencing is a Windows dll provided by GAMS, not a Python library.

Hi, did this commit end up in a pull request? That part of the code is still on NREL/master

In order to use gdxpds, you must not have gdx2py (from ererkka) installed. You may have gdx2py (from GAMS corportation) installed.
