I have problems compiling the backend. Which versions of QUDA and gcc did you use? Is the TF version from requirements.txt correct? thank you

[DongJT1996]

CUDA : 9.0, gcc : 5.4.0, the TF version is correct.

Whats your OS version? And did you maybe build Tensorflow yourself? thanks
I tied multiple versions of Tensorflow, Cuda, and GCC but always end up with one of these.

• "undefined symbol" when compiling the example Op tensorflow/tensorflow#9137
• fatal error: cuda/include/cuda.h: No such file or directory tensorflow/tensorflow#15002
• Undefined symbol: _ZTIN10tensorflow8OpKernelE CharlesShang/TFFRCNN#108

And somehow the fixes don't seem to apply in my environment... or at least i didn't figured out the right combination yet ^^

Ubuntu 16.04
I remember that I have modified some files of tensorflow similar to the following:

-#include "third_party/gpus/cuda/include/cuda.h"
+#include "cuda/include/cuda.h"

Maybe you can have a try.

I downgraded to Ubuntu 16.04 and everything works fine now thank you!
