I'm confused between which version of DIGITS to install

[RazaZaidi2802]

Apologies in advance since I'm new to all this but I'm confused regarding which version of DIGITS to install. I'm beginning a fresh install of the latest Ubuntu version and as of now, after hours of scouring the internet, I have found DIGITS versions that work standalone, versions that work in Docker, then there's the official DIGITS github page which has DIGITS upto version 6 and on the NGC, there's DIGITS 20.03???

What is going on I'm so confused. I was excited to get DIGITS up and running on my local machine just as soon as I had completed the Nvidia DLI's course and now I'm just stumped as to where to start. Would also like to know how different is DIGITS running for Tensorflow from the Caffe DIGITS.

Please help.
