Recently, I downloaded and installed the CUDA package for Julia. The CUDA toolkit version 6.5 was also installed on my windows.
I test package based on mentioned tutorial here: CUDA programming in Julia.
After that, Julia showed this error:
Loaderror: could not find a suitable CUDA installation
Package CUDA errored during testing
I tested CUDA toolkit in command prompt via:
nvcc --version
It showed the version.
I want to know what is wrong with the above procedure?
You’ll have to provide more details. Which version of Julia? Are you setting any environment variables?
That will not be used, CUDA.jl automatically downloads the CUDA toolkit. Also, this version is extremely old.
Try running with JULIA_DEBUG=CUDA and pasting the output here.
I use Julia 1.6.3 and I added the CUDA bin directory to the path. I previously run some code with Julia.
First: the output of the test procedure is:

Second, I cannot understand correctly:
Try running with
JULIA_DEBUG=CUDAand pasting the output here.
When I just run JULIA_DEBUG=CUDA, it showed:
ERROR: UndefVarError: CUDA not defined
When I just run JULIA_DEBUG=CUDA in test command, it showed:
ERROR: The following package names could not be resolved:

You need to set this in your environment before starting Julia.
like this
C:\Users\matt
$ set JULIA_DEBUG=CUDA
C:\Users\matt
$ julia -q
julia> ENV["JULIA_DEBUG"]
"CUDA "
julia>
Yes. You can also just set ENV before using CUDA. Maybe try that, because you seem to have a trailing space which make mess things up.
oh, good spot, but it seems that was just sloppy copy/pasting, I must have included one by accident
repeating it
$ set JULIA_DEBUG=CUDA
C:\Users\matt
$ julia -q
julia> ENV["JULIA_DEBUG"]
"CUDA"
Now import the package; this is just an env var that affects the behavior of CUDA.jl, and doesn’t do anything by itself.
I did it, I mean first:
ENV[“JULIA_DEBUG”] = “CUDA”
Then, I did:
using Pkg
Pkg.test(“CUDA”)
After that, It showed:
