FEW Cuda version requirement

[TinaMcNally]

Hello! I am a graduate student starting a project on EMRIs. I've recently installed FEW on my computer, and while all the tests for the CPU version function normally, the tests for my GPU fail, all due to a mismatched matrix dimension error. My GPU is cuda-enabled, but my cuda version is a bit old -- is there a required minimum cuda version for FEW that I'm missing?

Hi, I may have incurred on a similar issue,
Could you write:

1. the cuda version you are using
2. the actual error message you obtain
3. possibly other specification (OS)

I am not sure on the minimum version. Are either of you still having this issue?

In my case, it was a compatibility issue between NumPy and other packages (probably CuPy).
I solved it by reverting from NumPy 2.x (I do not remember the exact version, sorry) to NumPy 1.26 (specific version installed 1.26.4).
I have not done a new installation after July, so I am not whether this compatibility issue exists anymore.

For completeness’s sake, I leave the specifics of cuda and CuPy in my installation:

• cuda 12.1
• cupy-cuda12x 13.2.0
