Unexpected issue while building examples for movidius neural compute stick (ncsdk)

Question

Recently I bought Movidius Neural Compute Stick and I started with provided tutorial on the website. Make install works without any issue. However, despite following exact steps I'm constantly failing into same error while running make examples:

mvNCCompile -w bvlc_googlenet.caffemodel -s 12 deploy.prototxt
mvNCCompile v02.00, Copyright @ Movidius Ltd 2016

Failed to include caffe_pb2, things might go wrong!

My configuration is as follows:

sebastian@linux:~$ python --version
Python 2.7.12
sebastian@linux:~$ echo $PYTHONPATH
:/opt/movidius/caffe/python
sebastian@linux:~$ lscpu | grep "Model name"
Model name: Intel(R) Celeron(R) CPU N2840 @ 2.16GHz
sebastian@linux:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu

Codename: xenial

I'd appreciate suggestions what I need to do to succesfully build examples.

@shellter This directory exists in the tree. Note that this is pointing to non-existent graph file. Which is not created because of earlier error. — sebap123, Dec 26 '17 at 19:07
Oops, didn't read that close enough. I don't see how I can help on this one except to wonder about the `TypeError` message. Good luck! — shellter, Dec 26 '17 at 20:10

We did not find any issues during installation. Our configuration is as follows:

movidius@osboxes:~$ python --version

Python 2.7.12

movidius@osboxes:~$ echo $PYTHONPATH

:/opt/movidius/caffe/python

movidius@osboxes:~$ lscpu | grep "Model name"

Model name: Intel(R) Core(TM) i5-5300U CPU @ 2.30GHz

movidius@osboxes:~$ lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial

Could you please run the make clean command and try again installation using make install then do make examples.
