Upgrade protobuf 

pip install -U protobuf

which helps to resolve the issue

Hi Akihito,

Kind Regards,

Yes, I still facing the issue.

Could you tell me how to upgrade protobuf except for using openvino folder.

I used install_prerequisites_caffe.bat, and  protobuf-3.5.1-py3.6-win-amd64.egg, i don't know why protobuf doesn't upgrade.

Hope it's not too late. I had the same issue and resolved it by updating protobuf. I used anaconda package manager to install protobuf. 

# install the latest protobuf using anaconda package manager: conda install -c anaconda protobuf

Or if you don't use anaconda package, try this link: https://stackoverflow.com/questions/13616033/install-protocol-buffers-on-windows

(Not sure if this link works tho, cuz I'm working on Ubuntu.)
