Error while building Tensorflow using bazel

Question

I'm currently following the instructions here to build tensorflow from source using bazel.

After setting up the configuration, and attempting to build it, I get this error:

Cuda Configuration Error: Error reading C:/Program Files/NVIDIA GPU Computing To olkit/CUDA/v9.0/include/cudnn.h: java.io.IOException: ERROR: src/main/native/win dows/processes-jni.cc(239): CreateProcessW("grep" --color=never -A1 -E "#define CUDNN_MAJOR" "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v9.0/include/cu dnn.h"): Das System kann die angegebene Datei nicht finden.

The last phrase translates to "no such file or directory".

But I'm 100% sure I installed cuDNN 7.1.2 correctly, merging the downloaded bin/include/lib folder's with the preexisting CUDA folders. If I copy/paste the path from the error message, there it is cudnn.h! I also run everything in administator etc..

This problem shows up a few times on google, linking it to a mis-configured theano setup, but I'm not using theano right now. Why doesn't bazel find the file, when it's definitely there?

EDIT: I would also be very thankful if anyone has a link a pre-built version of tensorflow for CUDA compute capability 3.0!

Thank you in advance!

Answer 1

The error indicated that grep.exe can't be found. I tried grep for Windows and msys2. Both will do.
