Sorry about that, something in v2.15.6 broke our uv install for Linux users. As a temp workaround you can install uv system-wide and it should pick that one up and use it, but will also be getting fixed for v2.15.7 😄

Yes, I'm having the same error on Ubuntu and GeForce RTX 3060.

I'm having the same issue on OSX 26.3, M1 Pro.

Manually installing uv with brew install uv does not help either.
