Windows installation

First, unpack the protoc-3.2.0-win32.zip that can be found at https://github.com/google/protobuf/releases into the project folder. Now you should have a new protoc-3.4.0-win32 directory, containing a readme.txt and two directories, bin, and include. The folders contain a precompiled binary version of the protocol buffer compiler (protoc). All you have to do is add the protoc-3.4.0-win32 directory to the system path.

After adding it to the system path, you can execute the following command:

protoc-3.4.0-win32/bin/protoc.exe object_detection/protos/*.proto --python_out=.

That should be enough to allow the TensorFlow object detection API to work on your computer.
