Undefined symbol error with `torch==2.5.1`

[dhpitt]

I'm getting an error on Ubuntu when installing torch_scatter via conda install pytorch-scatter -c pyg. No error at install time, but when I import torch_scatter, it seems like it's compiled for the wrong torch version:

Python 3.10.14 (main, Mar 21 2024, 16:24:04) [GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import torch
>>> torch.__version__

Maybe try building from source?

It works well with torch 251 on Archlinux
