编译的原因是现有的whl无法直接安装，估计因为CPU不支持AVX。
参考的文章很多，google的最有参考意义:
https://tensorflow.google.cn/install/source_windows
要点是必须安装好MSYS环境，要手工安装patch命令，否则会报错的。
pacman -S unzip patch
pacman -S msys/patch
还有提前安装CUDA10.1/CUDNN7.4.
bazel默认会在用户主目录创建 _bazel_{user_name} 临时目录，要预留20G~50G的空闲空间。
bazel版本太高不行，太低也不行，最后用25.3才能编译。
VS2017可以成功，其他的版本不行。
首先执行
python configure.py
回答很多问题，此时AVX无法去掉。
等完毕后编辑刚刚生成的文件.tf_configure.bazelrc 去掉包含 AVX 的那行。
默认的vs2107 x64是支持SSE的，无须设置。
然后执行：
bazel build --config=opt --config=cuda --copt=-nvcc_options=disable-warnings //tensorflow/tools/pip_package:build_pip_package
