Tensorflow 1.7.1 error with python 3.5

I install tensorflow 1.7.1 to use with Unity ML-Agent. I install tensorflow with the following command:

pip3 install tensorflow==1.7.1

Installation goes fines but when I try to import tensorflow I got this error:

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/install_sources#common_installation_problems

for some common reasons and solutions.  Include the entire stack trace
above this error message when asking for help.
>>>

Microsoft C++ 2015 redistributable as installed on my system and I find MSVCP140.dll easily with the dos command ( like suggested in common installation issue docs ):

C:\>where MSVCP140.dll
C:\Windows\System32\msvcp140.dll

I don't install CUDA and cuDNN things because I don't have cuda cards and I only install tensorflow for CPU like suggested.

EDIT: Downgrading to TensorFlow 1.5 is not a solution for me because Unity ML-agents really need 1.7.1

Finally it's a AVX support problem. My CPU don't support AVX instructions.

I compile myself the TensorFlow 1.7.1 from sources. Finally not that hard as I think ( but take few hours on my poor laptop). With GIT , CMAKE , SWIG and Python 3.5 I fellow the instruction on the tensorflow github repo ( readme.md ):

https://github.com/tensorflow/tensorflow/tree/v1.7.1/tensorflow/contrib/cmake

Everything goes fine except few " out of heap space " errors. Trying to add the flags /Zm200 , /Zm500 or anything else not working for me. I solve this issue by forcing to use 64bit VC compiler:

https://github.com/tensorflow/tensorflow/issues/11096

On this issue page , the user kalengi suggest some tips. I only use his commands for MSBuild:

"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\amd64\MSBuild.exe" /m:2 /p:CL_MPCount=1 /p:Configuration=Release /p:Platform=x64 /p:PreferredToolArchitecture=x64 ALL_BUILD.vcxproj

"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\amd64\MSBuild.exe" /m:2 /p:CL_MPCount=1 /p:Configuration=Release /p:Platform=x64 /p:PreferredToolArchitecture=x64 tf_python_build_pip_package.vcxproj
