Here is how to use the apt package manger to display installed version too: On a Debian or Ubuntu Linux one can use the dpkg command as follows too:Ĭat "$(dpkg -L nvidia-cuda-toolkit | grep 'version.txt')" Using package manger Hence use the find command or whereis command to locate the Cuda directory and then run the cat command as follows for printing required information on screen: However, the location of this file changes. +-+ How do I know what version of CUDA I have insalled?įinally, we can use the version.txt file. | 0 N/A N/A 19466 G /usr/bin/nvidia-settings 1MiB | | 0 N/A N/A 5727 G /usr/lib/firefox/firefox 1MiB | | 0 N/A N/A 5653 G /usr/lib/firefox/firefox 1MiB | | 0 N/A N/A 4925 G /usr/lib/firefox/firefox 1MiB | | 0 N/A N/A 4701 G /usr/lib/firefox/firefox 246MiB | | GPU GI CI PID Type Process name GPU Memory | | Fan Temp Perf Pwr:Usage/Cap| Memory-Usage | GPU-Util Compute M. | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr. GeForce GPU from Fermi and higher architectureĪll you have to do is simply type the following command on your Linux or Unix terminal session:.The nvidia-smi command provides monitoring and management capabilities for each of the following NVIDIA cards: Outputs from my Ubuntu Linux 20.04 LTS deskop: nvcc: NVIDIA (R) Cuda compiler driverĬopyright (c) 2005-2019 NVIDIA CorporationĬuda compilation tools, release 10.1, V10.1.243 Using nvidia-smi command for displaying the CUDA version The NVIDIA CUDA compiler is called nvcc and it print version information easily: Finally you can query the /usr/lib/cuda/version.txt or /usr/local/cuda/version.txt as follows using the cat command to display the NVIDIA cuda version:.To check CUDA version use the nvidia-smi command:.Then type the nvcc -version command to view the version on screen:.Open the terminal application on Linux or Unix.The procedure is as follows to check the CUDA version on Linux. Sudo apt install nvidia-cuda-toolkit Finding the NVIDIA cuda version If not, simply type the following apt/ apt-get command to install the same: Update-alternatives: using /usr/local/cuda-11.NOTE: You must have an NVIDIA card with a driver installed on Linux along with a CUDA toolkit too. Press to keep the current choice, or type selection number: 1 There are 2 choices for the alternative cuda (providing /usr/local/cuda). usr/local/cuda-11.5 - priority 115 /usr/local/cuda-11.6 - priority 116Īnd To make the CUDA-11.5 is the active version # update-alternatives -config cuda Link currently points to /usr/local/cuda-11.6 Link best version is /usr/local/cuda-11.6 So we will install the previous CUDA Version # apt install cuda-11-5Īnd to display all CUDA Alternatives # update-alternatives -display cuda To confirm whether CUDA is working, reboot the system, then run the following command:īut what if we need to install CUDA 11.5, for example, need to run the CUDA 11.5 based cuDNN library libcudnn8 8.3.3.40-1+cuda11.5 If (you found your GPU Card is CUDA Supported) ' > ~/.bashrc Check your GPU Graphic Card for the CUDA Enabled feature, the compute capability listed here for Nvidia CUDA GPUs Graphic Cards.
