編譯的原因是現有的whl無法直接安裝，估計因爲CPU不支持AVX。
參考的文章很多，google的最有參考意義:
https://tensorflow.google.cn/install/source_windows
要點是必須安裝好MSYS環境，要手工安裝patch命令，否則會報錯的。
pacman -S unzip patch
pacman -S msys/patch
還有提前安裝CUDA10.1/CUDNN7.4.
bazel默認會在用戶主目錄創建 _bazel_{user_name} 臨時目錄，要預留20G~50G的空閒空間。
bazel版本太高不行，太低也不行，最後用25.3才能編譯。
VS2017可以成功，其他的版本不行。
首先執行
python configure.py
回答很多問題，此時AVX無法去掉。
等完畢後編輯剛剛生成的文件.tf_configure.bazelrc 去掉包含 AVX 的那行。
默認的vs2107 x64是支持SSE的，無須設置。
然後執行：
