I am following a use-deep-learning-to-assess-palm-tree-health tutorial. Since I do not have GPU on my computer, I used colab to train the SSD model with arcgis.learn and it was successfully completed.
When I use the trained model (either .emd or dlpk) in "Detect Objects Using Deep Learning" tool, i got error right after model definition selection.

I tested with the pre-trained model provided on the tutorial page, it works without any problem.
What could be the problem? Has anybody train SSD on colab for ArcGIS Pro?
