  • Hi @Narveer_241

    It looks like you are using on older version of the NCSDK v2. Could you try with version

    git clone -b ncsdk2
    cd <ncs dirrectory>
    make install
    make examples


  • Hi @Jesus_at_Intel ,

    I'm facing the same problem. I followed the instruction as given by you. The only thing I had to change was the if/fi condition in the that checks for AVX support (lines 42-45 in because if was failing with the error "Intel Advanced Vector Extensions support required but not detected". I referred to this post on this forum where someone else had this issue and I commented out those lines and it installed successfully.

    But when I go to "make examples" it throws me the same error as given by OP. Specifically, it's giving the "recipe for target X failed" where X is:
    1) googlenet
    2) apps/.
    3) multistick_cpp/.
    3) examples

    (Sorry I'm on a different machine else I would've copy-pasted the error).

    Can you please recommend the path forward. Since it does not give an pre-requisites (e.g. googlenet, TF, Caffee) that need to be installed, I did not install these.


  • Hi @anshulvj

    It's hard to pinpoint what the issue may be without the full error/log. Could you please share the whole error message and the NCSDK version you are installing?

    Give the following a try as I had a similar issue with the make examples.

    Uninstall the current SDK, run the following commands in the NCSDK directory
    make clean && make uninstall

    Remove the NCSDK directory and pull from github again.

    sudo rm -r <NCSDK Dir>
    git clone -b ncsdk2

    Remove any numpy packages & verify

    pip3 uninstall numpy
    pip3 list | grep numpy

    Install and make examples, run the following commands in the new NCSDK directory.

    make install
    make examples
