"""Diagnoses the current protobuf situation.
|
|
|
|
Protocol buffer needs to be properly installed for Caffe2 to work, and
|
|
sometimes it is rather tricky. Specifically, we will need to have a
|
|
consistent version between C++ and python simultaneously. This is a
|
|
convenience script for one to quickly check if this is so on one's local
|
|
machine.
|
|
|

Usage:
|
|
[set your environmental variables like PATH and PYTHONPATH]
