I just updated my graphics cards drives with

sudo apt install nvidia-driver-470
sudo apt install cuda-drivers-470

I decided to install them in this manner because they were being held back when trying to sudo apt upgrade. I mistakenly then did sudo apt autoremove to cleanup old packages. After restarting my computer for new drivers to get setup properly, I could no longer use GPU acceleration with tensorflow.

import tensorflow as tf
tf.test.is_gpu_available()

Have you installed cuda-toolkit? The error indicates that version 11 of the libraries is not found. The problem is that the cudatoolkit and the cudnn version could be incompatible with your tensorflow version.

If you already installed the correct version of the toolkit, go directly to Step 5. (You can check the version with the command nvcc --version).

  1. Download the installer from https://developer.nvidia.com/cuda-11-4-4-download-archive?target_os=Linux (this version is compatible with the driver nvidia-470 you installed). The next steps are specific to the runfile option.

  2. As you already installed nvidia-drivers, press Continue if this message appears.

  3. Accept the terms.

    enter image description here

  4. Again, as you already installed the drivers, just disable the Driver option and press Install.

    enter image description here

  5. Now you need to configure the paths for binaries and libraries. Using find command search for nvcc and libcublas.so.*:

    sudo find / -name 'nvcc'  # Path to binaries
sudo find / -name 'libcublas.so.*'  # Path to libraries

  6. Finally, add the next lines at the end of file ~/.profile according to the paths you found above. Cuda was installed on /usr/local/cuda-11.4 in my system.

    if [ -d "/usr/local/cuda-11.4" ]; then
    PATH=/usr/local/cuda-11.4/bin${PATH:+:${PATH}}
    LD_LIBRARY_PATH=/usr/local/cuda-11.4/targets/x86_64-linux/lib/${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
fi

If updating ~\.profile doesn't work, try to update .bashrc or .zshrc (in case you use zsh instead of bash).

  1. Restart the computer.

You can create symlinks inside of /usr/lib/x86_64-linux-gnu directory. I found it by:

$ whereis libcudart
libcudart: /usr/lib/x86_64-linux-gnu/libcudart.so /usr/share/man/man7/libcudart.7.gz

Within this folder you can find other versions of those cuda libraries. Then create symlinks like this. Your specific version that you are linking to might be slightly different.

$ sudo ln -s libcublas.so.10.2.1.243 libcublas.so.11
$ sudo ln -s libcublasLt.so.10.2.1.243 libcublasLt.so.11
$ sudo ln -s libcusolver.so.10.2.0.243 libcusolver.so.11
$ sudo ln -s libcusparse.so.10.3.0.243 libcusparse.so.11

Now your GPU should be detected.

True

This method works because these cuda libraries are similar enough that even NVIDIA build them with symlinks often. If tensorflow is looking for libcublas.so.11, you can create a file with that name that just points to another version of libcublas that is already installed.
