Hi,

I just format my labtop and install  
graphics drivers  
CUDA 11.2  
julia (1.53)

I added CUDA.jl and downloaded cuDNN111 via artifact and had no errors by here.

I ran Pkg\> test CUDA, now I got errors

ERROR: Package CUDA errored during testing

The errors are relatively short compared to what I had before I format the computer, but I am not sure whether I can go with CUDA, or I need to solve the error message.

Thanks,
