bazel在windows 10上构建tensorflow得到cudnn.h-系统找不到指定的文件

Question

尝试在Windows 10中使用bazel和python构建tensorflow-gpu时，我不断收到此错误：

Cuda Configuration Error: Error reading C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v9.2/cuda/include/cudnn.h: ja
va.io.IOException: ERROR: src/main/native/windows/processes-jni.cc(239): CreateProcessW("grep" --color=never -A1 -E "#de
fine CUDNN_MAJOR" "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v9.2/cuda/include/cudnn.h"): The system cannot fin
d the file specified.

这是我正在尝试运行的命令：

bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package

我已经确认C：/ Program Files / NVIDIA GPU计算工具包/ CUDA / v9.2 / cuda / include / cudnn.h就在那里。

我试过从VS2015 x64 Native Tools命令提示符，cmd和powershell运行它并得到相同的错误。

我正在使用bazel 0.16.1，CUDA 9.2，Anaconda3（Python 3.6.5）和CUDNN 7.2.1。我通过将其cuda文件夹解压缩到我的C：\ Program Files \ NVIDIA GPU Computing Toolkit \ CUDA \ v9.2文件夹（即整个“cuda”文件夹）来“安装”CUDDNN文件。我在运行configure.py时在cudnn路径问题中指定了C：\ Program Files \ NVIDIA GPU Computing Toolkit \ CUDA \ v9.2 \ cuda路径。 configure.py完成且没有错误。

我还尝试将CUDNN文件直接放在C：\ Program Files \ NVIDIA GPU Computing Toolkit \ CUDA \ v9.2文件夹中（而不是那里的cuda文件夹）并指定默认位置并仍然得到基本相同的错误：“ C：/ Program Files / NVIDIA GPU Computing Toolkit / CUDA / v9.2 / include / cudnn.h“：系统找不到指定的文件。

我已将这些添加到我的路径中（并重新启动）：

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.2\bin
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.2\libnvvp
C:\tools\msys64
C:\tools\bazel
C:\tools\bazel\bazel.exe
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.2\extras\CUPTI\libx64

这些是我设置的系统变量：

BAZEL_SH  C:\tools\msys64\usr\bin\bash.exe
BAZEL_VC  C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC
BAZEL_VS  C:\Program Files (x86)\Microsoft Visual Studio 14.0

这是完整的错误：

任何想法我可能做错了什么，或者我可能错过了什么，或者我接下来可以检查什么？

Answer 1

问题是cuda_configure.bzl中的一个错误：它使用ctx.execute而不是ctx.action.run_shell。如果你对file a bug to TensorFlow如此友善，那就太好了！

要解决此问题：将c:\tools\msys64\usr\bin添加到PATH中。这就是grep.exe所以ctx.execute可以在PATH上找到grep。
