Error loading PyTorch model definition

Trying to detect objects (swimming pools) with model provided from:

https://www.arcgis.com/home/item.html?id=16fa8bab78d24832b4a7c2ecac835019

I get the following error when model definition is validated in Detect Objects Using Deep Learning Tool from Pro 2.5:

ERROR 002667 Unable to initialize python raster function with scalar arguments.
Traceback (most recent call last):

Looks like there is a V function in:

c:\users\mike\appdata\local\programs\arcgis\pro\Resources\Raster\Functions\System\DeepLearning\PyTorch\model.py

Keras sample works fine. Followed directions to setup from:

GitHub - Esri/raster-deep-learning: ArcGIS built-in python raster functions for deep learning to get you started fast.

Ideas?

Thanks,

Mike
