I see. It was in Dev mode.
Dev mode is convenient, but it has bugs, such as the latest commit not being reflected. Also, in the case of Zero GPU Spaces, if something other than the spaces library touches CUDA first, it almost always crashes.
If there are .to("cuda") or .cuda() in the library, it’s pretty much a no-go.
Also, Zero GPU Spaces are CPU spaces except for those within the @spaces.GPU decorator, so installers that assume a CUDA environment will not work. Prebuilt binaries will probably work, though…
As a result, there are quite a few libraries that are effectively unusable. For details: zero-gpu-explorers/README · Discussions
