Problem running Tensorflow (Ubuntu 19.10) - python-3.x

Question

I've recently tried to install and run some python and tensorflow code from this repository.
I followed the manual installation procedure just as mentioned in the README.md present in the repository.
As I've never used tensorflow before, I had to install a lot of packages to get it up and running.
Currently, I've got tensorfow-gpu 1.13, python 3.7, and an Nvidia graphics card (mx250) on my Ubuntu 19.10 laptop, and I wish to get the code running. However, I'm having issues running the demo.sh file present with it.
Here's what I get in the err.txt when I run the command $ bash demo.sh > output.txt 2> err.txt at the cloned directory (after installing all required packages):

When you are going to use Tensorflow in GPU setup, have to carefully install and configure the Tensorflow in your machine. I would like to prefer to use Ubuntu 18.04 LTS version instead of 19.xx.
