torch_sparse and torch_scatter are not correctly installed when following the torch_geomtric installation instructions

😵 Describe the installation problem

When I try to run torch_geometric on a brand new conda environment, I get a warning from both torch_sparse and torch_scatter:

/anaconda3/envs/new_env/lib/python3.12/site-packages/torch_geometric/init.py:4: UserWarning: An issue occurred while importing 'torch-scatter'. Disabling its usage. Stacktrace: Could not load this library: /anaconda3/envs/new_env/lib/python3.12/site-packages/torch_scatter/_version_cuda.so
import torch_geometric.typing
/anaconda3/envs/new_env/lib/python3.12/site-packages/torch_geometric/init.py:4: UserWarning: An issue occurred while importing 'torch-sparse'. Disabling its usage. Stacktrace: Could not load this library: /anaconda3/envs/new_env/lib/python3.12/site-packages/torch_sparse/_version_cuda.so
import torch_geometric.typing

Method to recreate the problem:

1. Create a brand new conda environment conda create --name new_env python=3.12 and then activate it conda activate new_env;
2. Install pytorch: pip install torch torchvision --index-url https://download.pytorch.org/whl/cu128
3. Install torch_geometric: pip install torch_geometric
4. Install the optional stuff: pip install pyg_lib torch_scatter torch_sparse -f https://data.pyg.org/whl/torch-2.11.0+cu128.html
5. try to run anything that imports torch_geometric and you will see the above, quoted warnings.

Environment

• PyG version: 2.7.0
• PyTorch version: 2.11.0
• OS: Red Hat 8.6 (Ootpa)
• Python version: 3.12.13
• CUDA/cuDNN version: 12.8, I guess.
• How you installed PyTorch and PyG (conda, pip, source): see above instructions
• Any other relevant information (e.g., version of torch-scatter): no idea, I am just following the instructions

The line referenced in that warning is failing when it tries to import torch_scatter, when I try to import that package I see the following:

Traceback (most recent call last):
File "/anaconda3/envs/haai/lib/python3.12/site-packages/torch/_ops.py", line 1503, in load_library
ctypes.CDLL(path)
File "/anaconda3/envs/haai/lib/python3.12/ctypes/init.py", line 379, in init
self._handle = _dlopen(self._name, mode)
^^^^^^^^^^^^^^^^^^^^^^^^^
OSError: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by /anaconda3/envs/haai/lib/python3.12/site-packages/torch_scatter/_version_cuda.so)

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "", line 1, in
File "/anaconda3/envs/haai/lib/python3.12/site-packages/torch_scatter/init.py", line 16, in

raise OSError(f"Could not load this library: {path}") from e
OSError: Could not load this library: /anaconda3/envs/haai/lib/python3.12/site-packages/torch_scatter/_version_cuda.so

It appears I do not have a new enough version of GLIBC_2.32.
