Cuda 9

Hi Prabindh,

Will this work with cuda 9?

Thanks.

I have run it successfully with CUDA9.0 on the system (Windows). But this was a build compiled for CUDA8. I dont foresee issues compiling for CUDA9.0. Are you seeing any ?

hi Prabindh,

I tried the darknet and darknet-cpp binary and it worked fine with cuda 9.0 and cudnn 7.1. But with arapaho, it didn't work. Specifically, this line:

DPRINTF("Setup: layers = %d, %d, %d\n", l.w, l.h, l.n);

is printed as: Setup: layers = 0,0,0

and it doesn't detect anything.

Thanks.

Not even with arapaho, I tested the minimal code, and it always give Setup: layers = 0,0,0. The minimal code is the function test_detector() in detector.c. What I dont understand is darknet-cpp uses the same code and it just works fine. Is there any difference when compiling darknet-cpp and libdarknet-cpp-shared.so?

Thanks.

I am able to run the Arapaho app on Windows, with CUDA9.1. Please check whether the 3 options (GPU, CUDA, CUDNN) are the same in both cases - the DLL (.so) build, and your application (that uses the DLL/.so).

hi Prabindh,

My bad, I forgot to add -DCUDNN when compiling the application. It works fine.

Thanks.

Great. Thanks for the update.
