Python Can't find the mvnc module

I've been trying to setup the movidius library created by intel, but I keep getting stuck when I try to import the mvnc package.

To set up mvnc I followed the directions here: Real-time object detection with movidius

and when it comes time to test if the install works, I run

make examples

which gives this error whenever I run it.

Traceback (most recent call last):
File "/usr/local/bin/mvNCCompile", line 25, in <module>
from Models.Blob import *
File "/usr/local/bin/ncsdk/Models/Blob.py", line 19, in <module>
from Controllers.MiscIO import *
File "/usr/local/bin/ncsdk/Controllers/MiscIO.py", line 35, in <module>
from mvnc import mvncapi


So I'm wondering how it would be possible to get python to recognize the mvnc module so I can import it into any of my code. Thank you for your help!

I'm running Ubuntu 18.04.1 LTS in a virtual machine on a windows 10 computer

To perform the typical installation of the NCSDK, use the following command on your host machine:

git clone -b ncsdk2 http://github.com/Movidius/ncsdk && cd ncsdk && make install


You must enable a USB 3.0 controller and create USB whitelist filters for the virtual machine.

The USB 3.0 feature requires the VirtualBox Extension Pack.

Shut down the virtual machine

With the virtual machine selected on the VirtualBox Manager:

Open Settings -> USB
Check “Enable USB Controller”
Check “USB 3.0 (xHCI) Controller”
Add a new USB filter with Vendor ID: 03e7
The other filter fields can be blank.
Add a new USB filter with Vendor ID: 040e
The other filter fields can be blank


Use the following command in your ncsdk directory to download necessary prerequisites and models and build all examples:

make examples
