CUDA Installation Tips for UbuntuAs a rule of thumb, if all you need is an nvcc of a specific version, do not install CUDA in a system-wide way from the official NVIDIA website unless strictly necessary. It is generally tied to a specific version of the CUDA driver, which is not always compatible with your system. Worse still, it may break the drivers silently: the system works normally until it is rebooted and the X server fails to start. This post includes some ways to install CUDA in a conda environment and installing the driver if it breaks. Installing CUDA in a Conda EnvironmentFor CUDA version older than 12.0, use the cudatoolkit-dev package: conda install cudatoolkit-dev=11.3 -c conda-forge For CUDA version 12.0 or newer, use the cuda-nvcc package:
conda install cuda-nvcc cuda -c "nvidia/label/cuda-12.0.0"
Don't write cuda-nvcc=12.0. It usually comes with other CUDA-related packages with incompatible versions. Installing the Driver on UbuntuIt's generally easier (and safer) to install the driver from Ubuntu source. If the driver is already not working, switch to a text TTY (which does not require graphics driver) by Ctrl+Alt+F2. Check what versions are available by ubuntu-drivers devices Then, install the version you want by # replace 525 with the version you want sudo ubuntu-drivers install nvidia:525 |
