Problem of converting tensorflow model to Intermediate Representation (IR)

System information (version)

• OpenVINO => 2018.4.420
• Operating System / Platform => Windows 
• Framework => Tensorflow

Detailed description

Hi, I'm working on object detection using OpenVINO. However, I downloaded Inception Resnet tensorflow model (http://download.tensorflow.org/models/inception_resnet_v2_2016_08_30.tar.gz) and faced problem when converting this tensorflow model to Intermediate Representation (IR)  as follows. I tried other tensorflow model also faced same problem.

C:\xxx\OpenVino\inception_resnet_v2_2016_08_30>python C:\Intel\computer_vision_sdk_2018.4.420\deployment_tools\model_optimizer\mo_tf.py --input_meta_graph inception_resnet_v2_2016_08_30.ckpt

Please guide me how to solve this issue. 

Thank you very much.

Best regards,

Hi, I have found the solution, it seems like the existing protocol buffers version in my machine not match with OpenVINO, so it showed the error.

I installed the anaconda, put "pip install -U protobuf" and it solved the issue.

Shared to all in case someone also face similar problem.

Best regards,

Sunny
