+   When using the Deep Learning Reference Stack with Intel(r ) MKL-DNN version, you may see this warning message: "tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: SSE4.1 SSE4.2 AVX AVX2 AVX512F FMA". This is because this version of the Deep Learning Reference Stack is using Intel(r ) MKL-DNN for performance optimization rather than Intel(r ) Advanced Vector Extensions 512, and is expected for this version of the Deep Learning Reference Stack.
