How to check CUDA version on Ubuntu 20.04 step by step instructions
- The first method is to check the version of the Nvidia CUDA Compiler
nvcc
. To do so execute:$ nvcc --version nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2019 NVIDIA Corporation Built on Wed_Oct_23_19:24:38_PDT_2019 Cuda compilation tools, release 10.2, V10.2.89
- Given that you have the Nvidia driver installed on your Ubuntu 20.04 system, the following command will also reveal the CUDA version:
$ nvidia-smi Wed Jan 15 11:48:58 2020 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 440.44 Driver Version: 440.44 CUDA Version: 10.2 | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.

- If you did not changed the default CUDA installation path, you can also check the CUDA version simply by viewing the content of the
/usr/local/cuda/version.txt
file: - Check for installed CUDA toolkit package:
$ dpkg -l | grep cuda-toolkit ii cuda-toolkit-10-2 10.2.89-1 amd64 CUDA Toolkit 10.2 meta-package
$ cat /usr/local/cuda/version.txt CUDA Version 10.2.89
