Failure to install textgen-nvidia on WSL

[jasper-zanjani]

Be forewarned that I am a Nix newbie. I installed NixOS-WSL using the PowerShell block provided online. I then attempted to run

nix run github:nixified-ai/flake#textgen-nvidia

which eventually resulted in the following errors:

That's just because it's running the IPython upstream tests, and your computer may not be fast enough to run them, so it times out. The reason it's building everything from source is because as you see in the warning, you haven't trusted ai.cachix.org as a substituted, probably because you are not a trusted user in the Nix configuration.
