此时报错建议在我已经通过源代码逐一下载torch-scatter, torch-sparse, torch-cluster成果之后，然后下载torch_geometric发现成果下载，import 时弹出报错川口
无法定位程序输入点

在尝试重新下载torch失败之后，我问了查老师（chatgpt）发现在C++环境下无需指明版本下载，这时首先下载VSC++开发工具，链接下载链接
然后下载之后依次运行如下命令：
pip install torch-scatter -f https://pytorch-geometric.com/whl/torch-1.6.0+cpu.html
pip install torch-sparse -f https://pytorch-geometric.com/whl/torch-1.6.0+cpu.html
pip install torch-cluster -f https://pytorch-geometric.com/whl/torch-1.6.0+cpu.html
pip install torch-spline-conv -f https://pytorch-geometric.com/whl/torch-1.6.0+cpu.html
pip install torch-geometric
再次import成功。
