help needed with setting GPU (No CUDA GPU detected!, diagnostics: cudaError_t 30 : "unknown error" )

[Artur Zygadło]

Hello,

I am trying to run the nnet3 setting on my laptop with a single GPU (GeForce GTX 960M).

I guess it is not the wisest option to do so as it will take a lot of time, but anyway I am struggling to make it work.

I have installed CUDA 9.2 and nvidia-smi returns:

I have also compiled Kaldi src with CUDA enabled and it didn't throw any errors.

For some reason, while running steps/nnet3/train_dnn.py I keep getting an error:

ERROR ([5.3.81~1-829b0]:SelectGpuId():cu-device.cc:121) No CUDA GPU detected!, diagnostics: cudaError_t 30 : "unknown error", in cu-device.cc:121

I found out that the error is also thrown when I simply run the nnetbin/cuda-gpu-available... What can be the cause of this issue?

Best regards,
Artur Zygadło

I haven't seen that "unknown error" error before; I don't know how to
resolve it.

Did you do a make test after make?

Hey, have you tried running other apps that used gpu but without cuda?

[Ryan Sharif]

What version of gcc/g++ did you use to compile?
