Mask RCNN Labels and Object from Image not working

[dandon223]

I installed latte with Python 3.7.15 with conda, because >=3.8 is not working with versions of matplotlib and tenserflow in requirenment file.
I do not see any errors, but buttons with Mask RCNN Labels and Object from Image labels are not showing anything.

Did somebody else had this issue? @alvinwan @bernwang
