CUDA.jl not loading in julia 1.12.0

[maleadt]

CUDA.jl 1.12 compatibility is in the works. Try the master branch if you run into issues.

when opened julia 1.12.0 and issued the ‘using CUDA’ command, it just sits there doing nothing, essentially forever (20+ minutes waiting and still nothing)

Interrupt it (CTRL-C) and post the backtrace.

Ok, looks like there is a bug in the synchronization of parallel loading tasks… or something similar At least that’s what claude anthropic told me. And he found the following workaround, which is to edit the .julia/config/startup.jl file and add the following line:

ENV[“JULIA_DEBUG”] = “loading”

Don’t trust LLMs to debug issues like this. Adding debug logging only increases verbosity, and is not expected to be a valid workaround for anything.
