arcgis.learn.prepare_data() not working with RCNN Masks generated from ArcGIS 3.0

ArcGIS Pro 3.0

ArcGIS Python 2.0.1

DeepLearning Libraries 3.0

I am trying to run arcgis.learn.prepare_data() on an exported RCNN mask dataset. Dataset was generated from ArcGIS 3.0. I think there is an in compatability with the .emd file for RCNN mask in 3.0?

Error:
