dlopen failed to find runtime library on RTX5080

[tong1wu]

Description:
In order to support RTX5080. I've tried to download torch 2.7.0.dev20250310+cu128 and torch-scatter 2.1.2+pt27cu128.

torch_scatter-2.1.2+pt27cu128-cp310-cp310-win_amd64.whl

torch-2.7.0.dev20250310+cu128-cp310-cp310-win_amd64.whl

When I ran python -c "import torch_scatter; print('Success!')" there was an error

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Users\Tong\miniconda3\envs\scatter\lib\site-packages\torch_scatter\__init__.py", line 16, in <module>

    self._handle = _dlopen(self._name, mode)
OSError: [WinError 127] The specified procedure could not be found

It looks like torch-scatter is not compatible with torch version somehow. But I'm sure that the versions are matched.

Environment:
GPU: RTX5080
OS: Win11 x64
PyTorch version: 2.7.0
CUDA version: 12.8
Python: 3.10.0

Can anyone give me a hint about what's going on? Thanks.
