在Windows 10上获取cudnn.h的bazel构建tensorflow-系统找不到指定的文件

Question

在Windows 10中尝试使用bazel和python构建tensorflow-gpu时，我不断收到此错误消息：

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.

这是我要运行的命令：

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

我已经确认C：/ Program Files / NVIDIA GPU Computing Toolkit / CUDA / v9.2 / cuda / include / cudnn.h在那里。

我试过从VS2015 x64本机工具命令提示符，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。 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）中，我“安装”了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，没有错误。

我还尝试将CUDNN文件直接放置在C：\\ Program Files \\ NVIDIA GPU Computing Toolkit \\ CUDA \\ v9.2文件夹（而不是其中的cuda文件夹）中，并指定默认位置，并且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。

我已经将它们添加到我的路径中（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：

有什么想法我可能做错了什么，或者我可能错过了什么，或者接下来我可以检查什么？

问题是cuda_configure.bzl的错误：它使用ctx.execute而不是ctx.action.run_shell 。 如果您愿意向TensorFlow提交错误 ，那就太好了！

要解决此问题，请执行以下操作：将c:\\tools\\msys64\\usr\\bin到PATH。 那就是grep.exe所在的grep.exe ，因此ctx.execute可以在PATH上找到grep 。
