tkinter in notebooks for ArcGIS Online

Keep getting this error when trying to use tkinter in arcgis notebooks hosted in ArcGIS Online.



TclError: no display name and no $DISPLAY environment variable


From what I have seen it this is an environment variable that needs to be set in the docker image.  Using %env DISPLAY= does change variable but doesn't seem to clear up the issue.  I will then get this error:


TclError: couldn't connect to display ":0.0"


Since I do not have the control to alter these docker images used for Notebooks in ArcGIS Online I am wondering if someone from ESRI can look into this so tkinter works in notebooks for AGOL. 


My program runs fine when I run it from a jupyter notebook on my local machine.
