Hi, I have a pre-trained inceptionv3.pb file, and convert to graph file successfully without error.
But the infer result is all NaN in python.
Debug log didn't help anything.
Start download to NCS...

Hi,
I get almost the same error, using the same model, but with different tensor dimensions once 32 x32 in the second version 299 x 299:
- When I use the 32 x 32 model the prediction succeeds perfectly without errors.
- When I use the 299 x 299 model instead I can not continue getting the following debug:
