arcgis.learn.prepare_data() error calling dataset_type='RCNN_MASKS'

[Anonymous User]

Hi, 

I'm getting an error when calling the prepare_data function in arcgis.learn. The error seems to originate from the data.py file inside the arcgis.learn site-package, inside the dataset_type == 'RCNN_Masks' statement. The error says that the variable 'right' is not yet assigned (which is true because it seems it is only defined inside another dataset_type statement).

API version: 1.7.0

ArcGIS Pro 2.5

Sandeep, My classified tiles data looked just like that - but when the Train Model for Deep Learning tool failed, all that data disappeared -  it's gone -  is this is known issue? Can anyone shed light on this? This a huge amount of data to lose. Thanks - Marty Ryan
