不幸的是，我在启动时无法正确导入包Spyder。

from arch import arch_model
ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

我应该怎么办？谢谢！

解决方案

该软件包需要最新版本的numpy. 我试图删除numpy并重新安装版本1.20.0（所需的版本）但没有成功。蟒蛇会坚持1.19

最终，我做了很久以前我应该做的事。下载miniconda（不是anaconda）并只安装我需要的包。这样，使用conda!更新软件包时不会出现烦人的冲突。
