NVIDIA NVML Driver/library version mismatch [closed]

Question

When I run nvidia-smi I get the following message:

Failed to initialize NVML: Driver/library version mismatch 

An hour ago I received the same message and uninstalled my cuda library and I was able to run nvidia-smi, getting the following result:

After this I downloaded cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb from the official NVIDIA page and then simply:

sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb sudo apt-get update sudo apt-get install cuda export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}} 

Now I have cuda installed, but I get the mentioned mismatch error.

Some potentially useful information:

Running cat /proc/driver/nvidia/version I get:

NVRM version: NVIDIA UNIX x86_64 Kernel Module  378.13  Tue Feb  7 20:10:06 PST 2017 GCC version:  gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4) 

I'm running Ubuntu 16.04.2 LTS.

Kernel release is: 4.4.0-66-generic.

Thanks!

Surprise surprise, rebooting solved the issue (I thought I had already tried that).

The solution Robert Crovella mentioned in the comments may also be useful to someone else, since it's pretty similar to what I did to solve the issue the first time I had it.
