How to compile TensorFlow binary to use AVX2, AVX512F, FMA?

Question

When I call tf.Session() in TensorFlow, I obtain the following warning message:

I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 AVX512F FMA

My questions are:

1. How can I solve this? In particular, I wish to be able to keep the current TensorFlow version (1.12.0)
2. Will I obtain a considerable gain considering that I work on GPU?

I use Ubuntu 18.04.1 LTS.

Thank you ;)

Answer 1

1. I do not know how to keep 1.12.0, however the Tensorflow page has a good build guide: https://www.tensorflow.org/install/source#setup_for_linux_and_macos

2. According to comments from this thread at the Tensorflow github project, no. Quote:

From my experiments I found CPU-optimized GPU TF doesn't boost the performance significantly, but it can make the CPU cooler.
