The gpu_ctc function returns 0

[Lucia-Ningning]

Hello,when I use gpu_ctc function, it always returns 0, but with cpu_ctc, it returns the correct value. Can anyone gives me some advices on this? Any help would be appreciated, many thanks.

I had the same issue. Happened when I moved my code from a single 980ti to a pascal titan X (but also different machine, different OS)

From another issue with someone building on pascal, this solved it for me:

Edit cmakelists.txt:

set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} -gencode arch=compute_60,code=sm_60")
set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} -gencode arch=compute_61,code=sm_61")
set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} -gencode arch=compute_62,code=sm_62")''
