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

If you have installed CUDA SDK, you can run "deviceQuery" to see the version of CUDA

Answer 2

One can get the cuda version by typing the following in the terminal:

$ nvcc -V

# below is the result
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

---

Alternatively, one can manually check for the version by first finding out the installation directory using:

$ whereis -b cuda         
cuda: /usr/local/cuda

And then cd into that directory and check for the CUDA version.

Answer 3

if nvcc --version is not working for you then use cat /usr/local/cuda/version.txt

Answer 4

If you are running on linux:

dpkg -l | grep cuda

Answer 5

Programmatically with the CUDA Runtime API C++ wrappers:

auto v1 = cuda::version::maximum_supported_by_driver();
auto v2 = cuda::version::runtime();

This gives you a cuda::version_t structure, which you can compare and also stream, e.g.:

if (v2 < cuda::version_t{ 8, 0 } ) {
    std::cerr << "CUDA version " << v2 << " is insufficient." std::endl;
}

Answer 6

If you run

nvidia-smi

You should find the CUDA Version on the top right corner of the comand's output. At least I found that output for CUDA version 10.0 e.g.,
