Could not load dynamic library 'libcublasLt.so.11'; dlerror: libcublasLt.so.11: cannot open shared object file: No such file or directory

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.

Please make sure the missing libraries mentioned above are installed properly if you would like to use GPU. Follow the guide at https://www.tensorflow.org/install/gpu for how to download and setup the required libraries for your platform.

Solution

  • 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.
