AttributeError: '_thread._local' object has no attribute 'value'

I am trying to use the MRCNN sample for Object Detection and Instance Segmentation (Building Footprint detection). In the 'Detect Objects using Deep Learning' tool on Arcgis Pro, I am uploading the .emd file found in the 'examples' of 'MRCNN' folder in the 'Keras' folder. I have edited the .emd file by adding the full paths for "Architecture", 'Config', and 'ModelFile'. However, I have been encountering the error as follows, please help:
