Failed to execute (TrainDeepLearningModel).

I have cloned python evironment for deep learning. Installed all the requisite packages. Getting the flowing error, while executing Train Deep Learning Model tool from ArcGIS Pro 2.5. Any help would be highly appriciated.

i think you might need to elaborate a bit more as to what you were using and what inputs you used.

Also make sure all the prerequisites are installed as recommended on this site.
