1. 用管理权权限启动终端
2. 进入该conda环境后，pip show shapely看是否是1.7.1版本，卸载shapely后重新安装shapely

issue #1057

[FlyingQianMM]

windows上，在conda环境内通过pip install shapely后会出现该问题，具体可以看shapely issue https://github.com/Toblerity/Shapely/issues/1032

解决办法：

1. 卸载pip安装的shapely

pip uninstall shapely

2. 然后用conda安装

 conda install shapely==1.7.1

我也遇到了这个问题 只要升级到paddleX2.0 就会报这个错
