Yesterday i installad new version of Julia nad had to install packages once more and when i was instaling CUDA.jl i get warnings, when i call for CUDA in repl i get:  
┌ Error: CUDA.jl could not find an appropriate CUDA runtime to use.  
│  
│ You requested use of a local CUDA toolkit, but not all  
│ required components were discovered.  
│  
│ Try running with `JULIA_DEBUG=CUDA_Runtime_Discovery` in  
│ your environment and re-loading CUDA.jl for more details.  
│  
│ For more details, refer to the CUDA.jl documentation at  
│ [Overview · CUDA.jl](https://cuda.juliagpu.org/stable/installation/overview/)  
└ @ CUDA ~/.julia/packages/CUDA/TPbi4/src/initialization.jl:118  
I have had installed CUDA earlier and rather it didn’t have a problem. I tried to ask chatGPT and afterall i removed older cuda-toolkit and installed CUDA second time, hoping that it will be installed automatically. But still I got this problem and after all similar warnings have been dispalyed in Luc and MLJ installations (what’s expected). How can i fix it, cuz i don’t trust ChatGPT anymmore.

There are several forum posts recently about CUDA and Julia 1.12, did you check them out? E.g. [This one?](https://discourse.julialang.org/t/cuda-jl-not-loading-in-julia-1-12-0/133022/10)
