在 Intel Atom 上构建 Tensorflow 的错误

Question

我在 Intel Atom 上构建 Tensorflow。巴泽尔为 0.15。要构建的控制台命令是

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

我有

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

两个错误是

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

整个错误信息是

Answer 1

安装说明：

确保 numpy, keras-applications, keras-preprocessing, pip, six, wheel, mock 包安装在 Python 环境中正在构建和安装 TensorFlow。

克隆 TensorFlow 源代码并签出 1.12 分支

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

运行来自 TensorFlow 源目录的“./configure”
执行以下命令创建可用于安装优化的 TensorFlow 构建的 pip 包。

PATH 可以更改为指向特定版本的 GCC 编译器：
```
  export PATH=/PATH//bin:$PATH
```
LD_LIBRARY_PATH也可以是新的：
```
  export LD_LIBRARY_PATH=/PATH//lib64:$LD_LIBRARY_PATH
```
在您的机器上设置 GCC 支持的编译器标志，以使用英特尔® 数学核心函数库（英特尔® MKL）构建 TensorFlow。确保设置了适当的 "march" 和 "mtune" 标志。
```
  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
```
(或)

或者，设置适当的 "Instruction sets" 标志来编译库：

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

安装优化的 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>
