Adding user 'eepp' to 'users' group Setup is complete. The PYTHONPATH enviroment variable was added to your .bashrc as described in the Caffe documentation. Keep in mind that only newly spawned terminals can see this variable! This means that you need to open a new terminal in order to be able to use the NCSDK.

Build Examples
Problem One
cd ~/workspace/ncsdk make examples ... [Error 7] Toolkit Error: USB Failure. Code: No devices found
Fix One
- Macke Examples Error - followed Tome_at_Intel February 8 instructions
cd ncsdk/ make uninstall cd .. rm -rf ncsdk/ git clone https://github.com/movidius/ncsdk cd ncsdk/
Problem Two
making run .... ./run.py Traceback (most recent call last): File "./run.py", line 22, in <module> import cv2 ImportError: /opt/ros/kinetic/lib/python2.7/dist-packages/cv2.so: undefined symbol: PyCObject_Type Makefile:91: recipe for target 'run' failed make: *** [run] Error 1
Fix Two
Import Error ROS python3 opencv. ROS creates its own open cv which is compatible with python2 only. I do the following.I followed zishan’s instructions
sudo mv cv2.so cv2_renamed.so
I noticed that the NCS went away during the make run process. It no longer shows up in the lsusb list. I need to go through the VituralBox Devices -> USB menu to re-enable it.
I entered make run again.
Problem Three
make run ... Performing bulk write of 865724 bytes... Successfully sent 865724 bytes of data in 236.494626 ms (3.491068 MB/s) Boot successful, device address 2 Traceback (most recent call last): File "./run.py", line 58, in <module> device.OpenDevice() File "/usr/local/lib/python3.5/dist-packages/mvnc/mvncapi.py", line 147, in OpenDevice raise Exception(Status(status)) Exception: mvncStatus.ERROR Makefile:91: recipe for target 'run' failed make: *** [run] Error 1
lsusb confirms that the Vovidius NCS is not connected
