AVX support missing NCSDKv2 installation fails

make install ./ OpenCV uninstall starting Reading installer configuration variables from ./ncsdk.conf You are using pip version 8.1.1, however version 19.1.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command. OpenCV uninstall finished   make install starting. ./ Movidius Neural Compute Toolkit Installation Intel(R) Advanced Vector Extensions, Intel(R) AVX, support required but not detected. Will exit Makefile:47: recipe for target 'install' failed make: *** [install] Error 1

while running make. I get this error. I'm using Cuda version


nvcc --version nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2019 NVIDIA Corporation Built on Wed_Apr_24_19:10:27_PDT_2019 Cuda compilation tools, release 10.1, V10.1.168

Even if I go to & remove AVX check. I get some other error while caffee installation

Hi AArya8,

Are you using the NCS1?

It looks like your Intel Xeon x5650 CPU doesn't support AVX instructions. Tensorflow 1.6 and later started using AVX instructions in their prebuilt binaries. So you would have to use Tensorflow 1.5 or below or build from source.


Please let me know if you have any further questions.

Best Regards,

@Sahira_Intel​ I didn't get your answer. I have tensorflow-gpu installed 1.13.1. Maybe there's a problem with installing 1.13.1 CPU which ncsdk2 installs.....while doing make install


Is it the problem you are point to? Should I install tensorflow-cpu 1.5 lower in `virtual env`? & then try to install ncsdk2? Kind of confused plz clear....
