Can you use a Program like Stylegan 2 Offline? (No Google cloud)

Ok, I'm curious about it, as a fellow artist who heard about the Tezuka manga having a new AI launched version: https://wccftech.com/nvidia-stylegan-ai-used-to-create-tezuka-like-characters-in-new-phaedo-manga/

I'd like to ask to any connoisseurs of Python programming (mainly pickling and unpickling), how can I install Stylegan 2 offline and use it, since I have everything including the directories downloaded, however since the Stylegan 2 program is pickled can I even install it offline? The data I downloaded sums up a total of 200 GB so can my laptop even handle that? I could use some expert help case I'd like to try using the program offline first so I can get a better hang of it, before trying it online, but I cant find any offline instalation tutorials.
