Tensorflow ImportError When Using Screen

When trying to use Tensorflow in a remote setting using screen, I ran into the following error:

ImportError: libcublas.so.8.0: cannot open shared object file: No such file or directory

I forget where I found the fix, but the issue had to do with how screen preserves the environment variables of the system (It doesn't). Here's the fix:

screen env LD_LIBRARY_PATH=$LD_LIBRARY_PATH bash

This opens a new screen instance running bash with the appropriate shared libraries.

Tweaking Keyboard from the Command Line

I love swapping my CAPS and CTRL keys, and I never found the tweak tool solution to be very elegant. I found this quick solution, which didn't require me to install anything. I've included it below for reference. Great fix!

Open the following for editing:
sudo nano /etc/default/keyboard

And edit
XKBOPTIONS="ctrl:swapcaps"

Then, reconfigure:
sudo dpkg-reconfigure keyboard-configuration

And just go through the prompts as they are.
