I want to use [compute-sanitizer](https://cuda.juliagpu.org/stable/development/debugging/#compute-sanitizer) to look into a memory error, but when I run:

```julia
julia> using CUDA

julia> CUDA.compute_sanitizer()

```

I just get ERROR: UndefVarError: `compute_sanitizer` not defined. `CUDA.compute_sanitizer_cmd()` and `CUDA.run_compute_sanitizer()` aren’t defined for me either.

The documentation says “To facilitate using the compute sanitizer, CUDA.jl ships the tool as part of its artifacts,” which to my understanding, means I shouldn’t have to install anything outside of CUDA.jl in order to use the tool, but please correct me if I’m wrong.

If it helps, this is my versioninfo:

```julia

Build Info:
  Official https://julialang.org/ release

```

To add on, when I run

```julia
$ find ~/.julia/artifacts -name "compute-sanitizer"

```

I don’t find anything.

Someone I’m working with also has the same issue, so this may not just be a one-off issue. Does anybody have any ideas about this?

Ah, the documentation is out of date here. That piece should be removed, or updated to suggest using CUDA\_SDK\_jll which does still provide the `compute-sanitizer` binary (see e.g. how it’s done [in our test suite](https://github.com/JuliaGPU/CUDA.jl/blob/71311afa35463f3fce09ed73bae66f8810b5e821/test/runtests.jl#L185-L200)). Could you open an issue, or even better, a PR?
