CPU instructions not compiled with TensorFlow

Question

MacBook Air: OSX El Capitan

When I run TensorFlow code in terminal (python 3 tfpractice.py), I get a longer than normal waiting time to get back output

Answer 1

These are warning which mean it may be faster to build tensorflow on your pc from source.

However if you want to disable them, you may use the code below

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

this should silence the warnings. 'TF_CPP_MIN_LOG_LEVEL' represents the Tensorflow environment variable responsible for logging. Also if you are on Ubuntu you may use this code below

export TF_CPP_MIN_LOG_LEVEL=2 

I hope this helps.
