Unable to choose U-net as the model type in the tool 'train deep learning model'

[Roosvan_Rosmalen]

I am trying to do a land use classification with deep learning. However, after preparing my training data and exporting the training data for deep learning when trying to train the deep learning model I can't pick U-net as the model type, but only 'Single Shot Detector - Object detection' or 'RetinaNet - Object detection'. When I type in 'U-Net - Pixel classification' manually I get the following error:

ERROR 032659 updateParameters Execution Error: Traceback (most recent call last):
 File "c:\program files\arcgis\pro\Resources\ArcToolbox\toolboxes\Image Analyst Tools.tbx#TrainDeepLearningModel_ia.UpdateParameters.py", line 1, in <module>
 File "c:\program files\arcgis\pro\Resources\ArcToolbox\toolboxes\Image Analyst Tools.tbx#TrainDeepLearningModel_ia.UpdateParameters.py", line 65, in updateParameters
TypeError: getattr(): attribute name must be string

Does anyone have an explanation?

Hello Roosvan,

There are potential causes to the error message:

ERROR 032659 updateParameters Execution Error: Traceback (most recent call last)

But the most common cause is the error in the underlying deep learning Python package. Could you please check how did you install the packages?

• In Pro 2.5 and older, it is done via Python command line.
• In Pro 2.6, it can be done via the Installer.

The best way to troubleshoot this error is to reinstall the package completely.

Best regards,
Kanin
