Using CuPy on Maxwell GPU

Question

Anyone here trying to use cupy on a Maxwell GPU? I am trying to do a simple array.mean() operation and getting the message below. Is there a way I can get around this? Do I need to install a different cuda version? Different cupy version? Or do I need to resign to buying a new gpu?

I am running a GTX 980 with compute_cap of 5.2. I installed cuda in ubuntu using the latest docs from nvidia. Here is the output from nvidia-smi

Uninstalling latest cupy(13.0) from my conda env and installing a previous version did it for me:

In active env: conda install -c conda-forge cupy=12.3 cuda-version=12.4
