TypeError: unhashable type: 'numpy.ndarray'

Hi guys,

I was trying to use pandasgui to show a DataFrame stored in feather format (access the file from here - https://github.com/shanto268/HEP_DAQ/blob/master/CrateAnalysis/processed_data/events_data_frame_800.ftr ) and ran into the following error message, not entirely sure how to resolve this.

Looks like this is a duplicate of #35 which I thought I fixed but actually didn't. Should be fixed now if you want to test the latest commit pip install git+https://github.com/adamerose/pandasgui.git

Btw your data link is dead, checked out the repo and don't see a 'processed_data' folder.
