My machine is CUDA16.04, and CUDA10.0 was installed before. For some reasons, now I need to install CUDA9.0.
Download the run Version (if CUDA has not been installed before, you can download the deb version)
2. Follow the above tutorial
Sudo Chmod + X CUDA? 9.0.176? Linux.run? Add executable permissions for CUDA? 9.0.176? Linux.run
. / CUDA? 9.0.176? Linux.run? Install CUDA? 9.0.176? Linux.run
3. Setting of relevant parameters
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 384.81? (y)es/(n)o/(q)uit: n #I've installed CUDA10, so I don't need to install the 9.0 video card driver Install the CUDA 9.0 Toolkit? (y)es/(n)o/(q)uit: y /usr/local/cuda-9.0 is not writable. Do you wish to run the installation with 'sudo'? (y)es/(n)o: y #Use superuser rights Please enter your password: Do you want to install a symbolic link at /usr/local/cuda? # Whether to connect the installation directory through soft connection link reach /usr/local/cuda，yes or no Either, depending on whether you use it or not /usr/local/cuda Default cuda Catalog. (y)es/(n)o/(q)uit: y #I currently need to use 9.0 Enter Toolkit Location [ default is /usr/local/cuda-9.0 ]:#Direct carriage return
4. Setting of relevant environment variables after the completion of installation and transfer
Finished copying samples. =========== = Summary = =========== Driver: Not Selected Toolkit: Installed in /usr/local/cuda-9.0 Samples: Installed in /usr/local/cuda-9.0/Samples Please make sure that - PATH includes /usr/local/cuda-9.0/bin - LD_LIBRARY_PATH includes /usr/local/cuda-9.0/lib64, or, add /usr/local/cuda-9.0/lib64 to /etc/ld.so.conf and run ldconfig as root To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-9.0/bin Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-9.0/doc/pdf for detailed information on setting up CUDA. ***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 384.00 is required for CUDA 9.0 functionality to work. To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file: sudo <CudaInstaller>.run -silent -driver Logfile is /tmp/cuda_install_11003.log
As mentioned above, you need to set two variables: PATH and LD library PATH. Just modify them in. / bashrc file. Remember to source some. / bashrc to make it effective.
After the above steps are completed, multiple versions can be switched. You can directly modify / usr/local/cuda to point to different versions of CUDA.
