AttributeError: module 'mvnc.mvncapi' has no attribute 'EnumerateDevices'

Community Manager



OS Ubuntu 16.04.


I have installed the ncsdk 2 from the following source:


"git clone -b ncsdk2"


Install and make examples: OK


I have tested the NCS installation using the hello apps with success.


I want to use the the application "image-classifier" from ncappzoo, source:


"git clone"


When I execute "make run" or #python3 , I receive the following error:


AttributeError: module 'mvnc.mvncapi' has no attribute 'EnumerateDevices'


When I execute the Hello apps within the ncappzoo I have some errors, the last lines below:


cpp/hello_ncs.cpp:40:43: error: ‘mvncCloseDevice’ was not declared in this scope


retCode = mvncCloseDevice(deviceHandle);




cpp/hello_ncs.cpp:42:20: error: ‘MVNC_OK’ was not declared in this scope


if (retCode != MVNC_OK)




Makefile:10: recipe for target 'hello_ncs_cpp' failed


make: *** [hello_ncs_cpp] Error 1


For your information, the Python3 path output is:


python3 -c "import sys; print('\n'.join(sys.path))"


















Why the examples in the NCSDK run and the applications from ncappzoo do NOT work?


Please, do you have some suggestions to solve it?


Thank you

Have you switched to the ncsdk2 branch of the ncappzoo repository?
