Fixing the Tensorflow error: could not load dynamic library 'libcudart.so.11.0'

I tried to install and run Tensorflow on a Ubuntu 20.04 laptop with a Nvidia GPU but I encountered the "could not load dynamic library 'libcudart.so.11.0'" error message, as shown in the screenshot below.

To resolve the issue, I had to install the Nvidia kernel and Cuda 11 libraries from the Nvidia repository. The steps are outlined below.

  1. On the Ubuntu machine, open a Terminal. Type in the following commands to add the Nvidia ppa repository:

    $ wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin

    $ sudo mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600 && sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/7fa2af80.pub

    $ sudo add-apt-repository "deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/ /"

  2. In the Terminal, type in the commands to install the Nvidia kernel.

    $ sudo apt-get update && sudo apt-get install -y nvidia-kernel-source-460

  3. Finally, install Cuda with the following command.

    $ sudo apt-get -y install cuda

Subsequently when importing the Tensorflow library, the error message no longer appears.

Note: Download and install any additional missing libraries from https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/ if necessary.

Thank you, but I have done somethign horrible, I'm sure ._.

sudo apt-get -y install cuda
The following packages have unmet dependencies:
cuda : Depends: cuda-11-5 (>= 11.5.0) but it is not going to be installed

With Ubuntu 21.04:

pip3 install tensorflow
sudo apt install nvidia-cuda-toolkit

should resolve it.
