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

We have three ways to check Version: In my case below is the output:- Way 1:-

cat /usr/local/cuda/version.txt

Output:-

CUDA Version 10.1.243

Way2:-

nvcc --version

Output:-

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2017 NVIDIA Corporation
Built on Fri_Nov__3_21:07:56_CDT_2017
Cuda compilation tools, release 9.1, V9.1.85

Way3:-

/usr/local/cuda/bin/nvcc --version

Output:-

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Sun_Jul_28_19:07:16_PDT_2019
Cuda compilation tools, release 10.1, V10.1.243

Way4:-

nvidia-smi
NVIDIA-SMI 450.36.06    Driver Version: 450.36.06    CUDA Version: 11.0

Outputs are not same. Don't know why it's happening.
