OSError: [WinError 127] 找不到指定的程序。 #221

hi ，i am here .
I'm attempting to run the MatterGen model on my **Windows (CPU-only) computer to generate materials. However, I encountered persistent errors when installing and loading three critical dependencies: torch-scatter,*torch-cluster, and *torch-sparse (required by torch-geometric, which is essential for MatterGen).

Issue Description:
When trying to import these three libraries (e.g., import torch_scatter), the following error consistently occurs:

OSError: [WinError 127] The specified procedure could not be found.  
OSError: Could not load this library: [path_to_venv]\Lib\site-packages\torch_scatter\_version_cpu.pyd

Troubleshooting Steps Already Attempted

1. Official Source Installation: Tried installing the libraries via their official PyTorch Geometric wheel links, matching the PyTorch version (initially 2.7.0, later downgraded to 2.3.0 for better compatibility) and my Python 3.10 (64-bit) environment.
   $ pip list | grep torch
   torch 2.7.0+cpu
   torch_cluster 1.6.3+pt27cpu
   torch-geometric 2.7.0
   torch_scatter 2.1.2+pt27cpu
   torch_sparse 0.6.18+pt27cpu
   torchaudio 2.7.0+cpu

2. Visual Studio Installation: Installed Visual Studio 2022 Build Tools with the "Desktop Development with C++" workload to ensure the MSVC compiler and C++ runtime libraries are available.

3. Manual DLL Copy: Located the required C++ runtime DLLs (msvcp140.dll, vcruntime140.dll, vcruntime140_1.dll) from the Visual Studio redistributable directory and copied them directly into the installation folders of torch-scatter, torch-cluster, and torch-sparse.

Request

i want to ask:

1. What other potential causes could lead to this "failed to load .pyd library" issue on a Windows CPU environment?
2. Are there any additional troubleshooting steps or alternative solutions to get these dependencies working properly for running MatterGen?

thank you very much
