pytorch-几何库ImportError: DLL加载失败:找不到指定的过程

Question

我正在尝试安装pytorch-geometric，但是当我调用import torch_geometric时，我得到了错误：

ImportError: DLL load failed: The specified procedure could not be found.

我的pytorch几何版本是：

# pytorch-geometric         1.7.2           py37_torch_1.9.0_cu111    rusty1s 

pytorch版本：

我是不是遗漏了什么？这里有没有人遇到过这个问题？

Answer 1

正如talonmies所说，它与scipy安装有关。在重新安装、升级或使用pip时不起作用。它确实在一个新的虚拟环境中工作。仍然不确定之前环境中的错误所在
