How to get the cuda version?

Question

Is there any quick command or script to check for the version of CUDA installed?

I found the manual of 4.0 under the installation directory but I\'m not sure whether

Answer 1

For CUDA version:

nvcc --version

Or use,

nvidia-smi

For cuDNN version:

For Linux:

Use following to find path for cuDNN:

$ whereis cuda
cuda: /usr/local/cuda

Then use this to get version from header file,

$ cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

For Windows,

Use following to find path for cuDNN:

C:\>where cudnn*
C:\Program Files\cuDNN7\cuda\bin\cudnn64_7.dll

Then use this to dump version from header file,

type "%PROGRAMFILES%\cuDNN7\cuda\include\cudnn.h" | findstr CUDNN_MAJOR

If you're getting two different versions for CUDA on Windows - Different CUDA versions shown by nvcc and NVIDIA-smi
