Protobuf error - truncated message

[woodthom2]

Hi

I am running TensorFlow 0.11.0rc0 on Python 3.5 with Mac OSX 10.11.6 and libprotoc 2.6.1.

When I try to convert a model (new Caffe format) I get this Protobuf error...
Has anyone seen this before?

OK I switched to Python 2 with the default TensorFlow installation in Anaconda, and it worked:

I closed it but it may be worth keeping an eye on the issue as more people start using Python 3.

Same issue here, because I am using TensorFlow in Windows, where Python3 has to be used instead of Python2. This issue stops me using this project. T_T.

It is likely that this is the issue affecting you
protocolbuffers/protobuf#3734

If you have such a problem using different Python versions or using Windows consider running it with Docker:
