Hi! I run `test CUDA` to ensure that everything works as expected. But some errors occurred as below. Are these errors related to the test file or the configuration of the system? How can I resolve them? Thanks!

I have also tried the same thing, like configuring Nvidia driver and CUDA toolkit again on another virtual machine, but still got the same errors.

That’s a bug in the CUDA.jl test suite; it looks like `llvm.nvvm.wmma.m8n32k16.load.a.col.stride.u8` is only supported on Turing (sm\_75+). Please file an issue, including this information and a full backtrace in textual form (i.e. not a screenshot). Also make sure to note which version of CUDA.jl you are using (versioninfo() currently does not report that).

Ok, I will do that. Thanks!
