Hi,
We are trying to process a trained model (tensorflow 1.14) using mo_tf.py and are getting bugs.
The following is the python script we use to train and save the model and after that the bugs we are getting. It seems to complain about:
Shape [-1] is not fully defined for output 0 of "Placeholder_1".
If you could indicate what we have to change in our python script that would be great !
Thanks a lot and regards,
David.

Hi @David,
Seems like you are using OpenVINO 2019 R2 version, could you update to R3 and let me know if you encounter the same error.
Regards
Roy

Hi Roy,
Thanks for this information, we will try updating OpenVINO, rerun and let you know the result.
Best regards,
David
