TLDR

When hit with an AVX AVX2 warning from TensorFlow, choose one of these solutions:

  • Ignore it, if performance isn't an issue for your project.
  • Use pre-built TensorFlow supporting AVX via pip install tensorflow.
  • Compile TensorFlow from the source code for ultimate CPU performance.
  • Upgrade your CPU, with native AVX support to dodge the warning.

Dismiss the warnings with this Python command:

import tensorflow as tf tf.compat.v1.logging.set_verbosity(tf.compat.v1.logging.ERROR)

This line keeps TensorFlow functional while blocking out the noise.

Maximize CPU Performance

When a GPU is not available, maximize CPU performance by building TensorFlow from source. Optimize it with AVX, AVX2, and FMA support for your CPU type.

Unleash the Power of Intel MKL

Accelerate inference up to 3x faster on Intel CPUs using Intel MKL optimized TensorFlow wheels. Looking for the right wheel file? Windows users, ensure your CPU instruction sets compatibility.

Hitting two birds with one stone: CPU & GPU

Use your CPU and GPU concurrently to optimize TensorFlow's performance during both training and inference. By assigning some input pipeline operations to the CPU, your GPU remains uncluttered, achieving a substantial performance boost.

Following the GP-Who? Performance Guide!

Check out TensorFlow's performance guide to dabble into a plethora of tips. It offers 3x performance enhancements using optimal configurations.

Grabbing the Right Binary from GitHub

Your CPU's got a lot going on, and so does TensorFlow. Confirm your CPU's capabilities match the TensorFlow wheel files on GitHub. Opt for the one that aligns with your Python version and CPU instruction set extension.

CPU-only TensorFlow Tasks

For CPU-bound TensorFlow operations without GPU offloading, opt for a source installation. With the right AVX extensions, you can maximize your CPU's potential.

Fixing Compatibility Errors, 101

Encounter a "File is not a zip file" error or related compatibility issues? No worries, you can download the wheel file and perform a local installation. Update the TensorFlow with an optimized binary using a simple command:

# Winding up the wheels manually, aren't we 'wheely' good at this? pip install --ignore-installed --upgrade /path/to/downloaded/wheel

Troubleshooting with Style

Facing AVX and AVX2 support errors? Overcome them by updating your TensorFlow to a compatible version. You can also create a custom build optimized for your CPU environment. This should 'TensorFlow' your worries away!
