Running int8 model on Intel-Optimized-Tensorflow


I read the article

It mentioned that the 2nd generation instructions such as AVX512_VNNI are optimized for Neural Network

I ran one of INT8 models in IntelAI

Here is my environment

- Docker:

- CPU info

I expect to run the Neural Network by the 2 gen instructions (AVX512_VNNI)

but it shows that the following optimized instructions are used:


Is the docker image the optimized version to run Neural Network?

​How can I get the information whether AVX512_VNNI is used or not?

How can I compile the code provided by IntelAI by the 2 gen Intel instructions?

Which docker image can I use to run the program?

Thanks in advance
