undefined symbol: _ZN5torch3jit17parseSchemaOrNameERKSsb

Hi,

I already had the problem with PyTorch 2.5 and now with PyTorch 2.6: I get an undefined symbol: _ZN5torch3jit17parseSchemaOrNameERKSsb error when I import torch_cluster. I'm using a cpu only version of PyTorch. I've tried it with PyTorch from conga-forge and with PyTorch from download.pytorch.org (installed with pip). I got exactly the same error message:

Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pt26/lib/python3.11/site-packages/torch_cluster/__init__.py", line 18, in <module>
torch.ops.load_library(spec.origin)
File "/tmp/pt26/lib/python3.11/site-packages/torch/_ops.py", line 1357, in load_library
ctypes.CDLL(path)
File "/tmp/pt26/lib/python3.11/ctypes/__init__.py", line 376, in __init__
self._handle = _dlopen(self._name, mode)
^^^^^^^^^^^^^^^^^^^^^^^^^
OSError: /tmp/pt26/lib/python3.11/site-packages/torch_cluster/_version_cpu.so: undefined symbol: _ZN5torch3jit17parseSchemaOrNameERKSsb```

I appreciate any hints.

Also met the same problem, my Pytorch version is 2.5.1 with cuda12.4.
