AICoE TensorFlow builds are optimized for AVX2 instruction sets supported in the CPU identified
The CPU model used supports AVX2 instruction set that can speed up TensorFlow machine learning models. The recommendation is to use AICoE builds of TensorFlow published at AICoE index.
TensorFlow builds available on PyPI are not build with compiler flags that would turn on AVX2 instructions. TensorFlow builds on the AICoE index are built with compiler options to enable AVX2 instructions in the resulting artifact installed.
