You should consider upgrading via the 'pip install --upgrade pip' command.

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

@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....
