I have installed AMDGPU.jl and have been using it in the Julia REPL. I tried

> using AMDGPU

inside Pluto notebook and I got the error:

> Error message

> Malt.TerminatedWorkerException()

What’s happening and how do I fix it?

Malt.jl is the underlying package that Pluto uses to run notebook code in an external process. A `TerminatedWorkerException` means the whole process (i.e. notebook) crashed.

If you can use AMDGPU.jl normally from the REPL, it might be worth opening an issue on github.

I’ve also run into this error when running a Pluto notebook in a Docker container on a Mac M4, I’m not using any GPU.

I encountered this problem on Arch Linux with ROCm installed through the AUR. It seems like the installation was imperfect.  
I installed Debian which is officially supported by AMD for ROCm, installed ROCm by using the instructions on the AMD website and then tried the same thing and it worked fine in the Pluto notebook.

A good check for if it is a driver issue is the following:

> using AMDGPU  
> AMDGPU.versioninfo()
