Issue with tensorflow-mkl on CPU

Question

I am new to tensorflow. In fact using it because the server code I am writing calls that.

I am using conda to setup the various packages. I did conda install -c anaconda tensorflow-mkl. (Note: I dont have a GPU - using a CPU) I always get this error:

Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX

The specific line of code where this happens:

tensorflow.contrib.predictor.from_saved_model(path)

On further research, I figured out that this is because the tensorflow package I have does not support this above instruction and needs to have support for the same.

Some questions: 1. How do we ensure the tensorflow package I have does support the above function? Any source from which I can download?

2. If it is not important, is there a way to suppress this instruction or any errors from it?

Thanks in advance!

Answer 1

You can use conda or pip installations to download the tensorflow that supports cpu. You can use the following commands from your terminal

conda install tensorflow -c anaconda

or

pip install tensorflow==1.13.1

You can use this link if you havent installed pip yet

Hope this helps..

Answer 2

Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX

This is just a warning.Not an error.

To suppress this warning please add the following lines before your actual code:

import os
os.environ['TF_CPP_MIN_LOG_LEVEL']='2'
import tensorflow as tf

As per the tensorflow official documentation,starting with TensorFlow 1.6, binaries use AVX instructions which may not run on older CPUs.
