Good work! But, iirc there were some issues about setup script failing in some scenarios, it would be great if you could check that, and resolves those here itself.

So turns out the following changes helped:

• Increasing the git buffer size
• Using HTTPS over HTTP/2

Great! I noticed both of these PRs are addressing similar issues: (#188). It would be best if both of you collaborated to integrate these fixes into a single PR. You can work together to refine the solution and submit a combined PR. Let me know if you need any help! 🚀

So basically we have made a few improvments after discussing it together :-

• Added debugging
• Resolved the problem with installing the thinc and torch packages
• Added documentation
• Removed deactivate command so that the user can have the server running on script execution (tested)
• Added colours for representing errors and successes correspondingly
• Add command in script to perform the setup automatically (extraction,running server)
