Error when running GPU simulation: Unable to cast Python instance to C++ type (PyOpenCL / PySPH)

[EUDE SILVA]

Hello everyone, my name is Eude Lucas.

I'm trying to simulate the fall of multiple particles onto a surface — essentially free fall with several particles.

The simulation runs normally when I use a machine with a powerful CPU (64 cores), but when I try to run it on the GPU (NVIDIA RTX A6000 or NVIDIA RTX A4500), I encounter errors that I haven’t been able to solve yet. I’ve attached an image showing one of the errors.

Could anyone give me some guidance on how to resolve this issue?

Thank you in advance for your help!
