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

我该怎么办？谢谢！

Answer 1

该软件包需要最新版本的 numpy。我尝试删除 numpy 并重新安装版本 1.20.0（需要的版本）但没有成功。 Anaconda 会坚持 1.19

最终，我做了我早就该做的事。下载 miniconda（不是 anaconda）并只安装我需要的包。这样，使用 conda!

更新软件包时就不会出现恼人的冲突
