I want to use julia on GPU.  
So I installed CUDA by `add CUDA` and wrote the following code.

```julia
julia> using CUDA
julia> y = CUDA.fill(2.0, 3)

```

I have been waiting more than an hour but still no response.  
It seems to freeze. If I interpreted with `ctrl + c`, I got the following errors:

```julia

```julia
julia> using CUDA

julia> has_cuda()
true

```

I also confirmed there was no waiting job on GPU.  
I need your help. What should I do?

EDIT

I noticed the versions of cuda and cudnn were not up to data.  
I am not admin so i need to request to update them…

Does this happen on all calls? Can you execute any others? e.g:

```julia
y=CUDA.zeros(8,8)

```

Yes.  
`CUDA.zeros` also makes freeze.

`cuDevicePrimaryCtxRetain` hanging is unlikely to be an issue with CUDA.jl, but is indicative of a deeper issue. Can you check `dmesg`? Try using different devices by starting Julia with the `CUDA_VISIBLE_DEVICES` env var set to a device number, or by using `CUDA.device!` at the start of a session. It may be that certain devices are specially configured, e.g., to only allow a single compute process.

Thank you for your comments.

# Checking `dmesg`.

I used the `dmesg` command. Many responses appeared as follows, but I am a beginner at management GPUs, so I don’t know what is going on.

I’m not familiar with that specific error message, but generally any NVRM exceptions in your dmesg log is bad. So I’d guess that your set-up is broken.

Do you mean the setting up of CUDA.jl and Julia is broken? or do you think the setting up of the GPU driver is broken?

The NVIDIA driver. Try rebooting, and if that doesn’t help, maybe testing some CUDA C applications to see if they work.

I have reinstalled the NVIDIA driver, and the problem has been solved.  
Thank you.
