错误处理：安装torch-sparse、torch-spline、torch-scatter、torch-cluster

问题描述

安装torch-sparse的时候，出现了这样的错误

pip install torch-sparse

 ValueError: underlying buffer has been detached

问题是安装的torch-sparse和已经安装好的torch版本不适配

解决方法

1）查看pytorch版本

>>> import torch
>>> print(torch.__version__)
1.7.1+cpu

2）去  https://pytorch-geometric.com/whl/index.html 找相应的版本

3）点开‘torch-1.7.1+cpu

4）选择相应的版本，下载之 

下载哪个版本的教程见：报错解决方法1：‘A GDAL API version must be specified.’_UQI-LIUWJ的博客-CSDN博客

5） 安装
