Errors on building Tensorflow on Intel Atom

I build Tensorflow on Intel Atom. Bazel is 0.15. The console command to build is

bazel build --config=mkl --cxxopt=-D_GLIBCXX_USE_CXX11_ABI=0 --copt=-march=atom --copt=-mtune=atom //tensorflow/tools/pip_package:build_pip_package

I have

Python 3.5.2 (default, Nov 12 2018, 13:43:14) 
[GCC 5.4.0 20160609] on linux

Two errors are

ERROR: /home/upsquared/tensorflow/tensorflow/BUILD:533:1: Executing genrule //tensorflow:tf_python_api_gen_v1 failed (Exit 1)
Traceback (most recent call last):

The whole error messages are

Solution

Installation instructions:

Ensure numpy, keras-applications, keras-preprocessing, pip, six, wheel, mock packages are installed in the Python environment where TensorFlow is being built and installed.

Clone the TensorFlow source code and checkout 1.12 branch

git clone https://github.com/tensorflow/tensorflow
git checkout r1.12

Run "./configure" from the TensorFlow source directory
Execute the following commands to create a pip package that can be used to install the optimized TensorFlow build.

PATH can be changed to point to a specific version of GCC compiler:
```
  export PATH=/PATH//bin:$PATH
```
LD_LIBRARY_PATH can also be to new:
```
  export LD_LIBRARY_PATH=/PATH//lib64:$LD_LIBRARY_PATH
```
Set the compiler flags support by the GCC on your machine to build TensorFlow with Intel® Math Kernel Library (Intel® MKL). Ensure appropriate "march" and "mtune" flags are set.
```
  bazel build --config=mkl --cxxopt=-D_GLIBCXX_USE_CXX11_ABI=0 --copt=-march=sandybridge --copt=-mtune=ivybridge --copt=-O3 //tensorflow/tools/pip_package:build_pip_package
```
(or)

Alternatively, set appropriate "Instruction sets" flags you want to compile the library with:

Flags set in the command below will add AVX, AVX2 and AVX512 instructions which will result in "illegal instruction" errors when you use older CPUs. If you want to build on older CPUs, set the instruction flags accordingly

       bazel build --config=mkl -c opt --copt=-mavx --copt=-mavx2 --copt=-mfma --copt=-mavx512f --copt=-mavx512pf --copt=-mavx512cd --copt=-mavx512er //tensorflow/tools/pip_package:build_pip_package

Install the optimized TensorFlow wheel

bazel-bin/tensorflow/tools/pip_package/build_pip_package ~/path_to_save_wheel

pip install --upgrade --user ~/path_to_save_wheel/<wheel_name.whl>
