Im trying to convert a image classification model built using tensorflow 2.x that uses Efficientnet b0 pretraining. However I keep receiving the same error. I also receive error if I try to convert fresh model from open model zoo in DL workbench

Error Log below

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

Hi Pritesh156,

Thank you for reaching out to us.

 

I've validated from my end using Efficientnet-b0 model and encountered similar errors when converting the model using OpenVINO DL Workbench 2022.1.

 

We are investigating this issue and in the meantime, I suggest you use openvino-dev Python package in converting your models.

 

For your information, I was able to successfully convert Efficientnet-b0 using openvino-dev[tensorflow2] Python package as shown below:

Regards,

Hairul
