Tensorflow cannot open libcuda.so.1

Question

I have a laptop with a GeForce 940 MX. I want to get Tensorflow up and running on the gpu. I installed everything from their tutorial page, now when I import Tensorflow, I get

Answer 1

libcuda.so.1 is a symlink to a file that is specific to the version of your NVIDIA drivers. It may be pointing to the wrong version or it may not exist.

# See where the link is pointing.  
ls  /usr/lib/x86_64-linux-gnu/libcuda.so.1 -la
# My result:
# lrwxrwxrwx 1 root root 19 Feb 22 20:40 \
# /usr/lib/x86_64-linux-gnu/libcuda.so.1 -> ./libcuda.so.375.39

# Make sure it is pointing to the right version. 
# Compare it with the installed NVIDIA driver.
nvidia-smi

# Replace libcuda.so.1 with a link to the correct version
cd /usr/lib/x86_64-linux-gnu
sudo ln -f -s libcuda.so. libcuda.so.1

Now in the same way, make another symlink from libcuda.so.1 to a link of the same name in your LD_LIBRARY_PATH directory.

You may also find that you need to create a link to libcuda.so.1 in /usr/lib/x86_64-linux-gnu named libcuda.so
