Make Examples Error

Hi all,

 

I am running into an issue when running 'make examples'. It keeps failing on the making compile step due to an import error. I have opened a new terminal session since running the install, and successfully run the 'hello_ncs.py' example program. This is happening on an Ubuntu 16.04 Virtual Box image on a Win7 Host. I also tried running the pip install separately for pygraphviz.Here is the traceback:

 

osboxes@osboxes:~/ncsdk$ make examples

Re: Make Examples Error

@apie Try going to the caffe/GoogLeNet directory and see if you can successfully do a make compile. If you can’t, I would recommend reinstalling the ncsdk and seeing if that solves the issue.

 

You can perform an uninstall of the NCSDK by entering the ncsdk root directory and typing in: make uninstall

 

Afterwards delete the ncsdk folder and its contents

 

Download a fresh copy of the NCSDK at https://github.com/movidius/ncsdk or do a Git clone https://github.com/movidius/ncsdk to your desired location.

 

Navigate to the ncsdk folder you just downloaded and type in: make install

Re: Make Examples Error

Hello @Tome_at_Intel ,

 

I have tried the solution that you have suggested above. I re-cloned the fresh copy of NCS and tried 'make compile' (after make install is successful). But I'm still getting the same error that is mentioned in the above thread. I would appreciate if you can help with any workarounds to create a graph file. Thanks !!

 

Hi @apie, the above mentioned solution didn't work for me. Can you please update the thread if you have found any alternative solution for this? Thanks !!

Re: Make Examples Error

Hello, I actually I got this error resolved. There was an issue with multiple python versions available in the system. So here is what i did.

 

     

  • Removed pygraphviz from both python versions. (pip2/pip3 uninstall pygraphviz)
  •  

  • rm -rf /usr/local/lib/python3.5/dist-packages/pygraphviz && rm -rf /usr/local/lib/python2.7/dist-packages/pygraphviz
  •  

  • pip3 install pygraphviz --install-option="--include-path=/usr/include/graphviz" --install-option="--library-path=/usr/lib/graphviz/"
  •  

 

You can refer to this link if you still have any issues with pygraphviz.

 

Thanks !!

Re: Make Examples Error

Hi madhusudhan_s ,

 

Your suggestion is work. Ubuntu 16.04 python 3.5.

 

I think the problem is mismatch library in pip wheel and ubuntu /usr/lib.
