无法导入最新的 (0.12.2) statsmodels.api：获取类型错误：需要一个整数获取类型字节

编程问答 2022-05-23

问题描述

无法导入 statsmodels.api as sm, 但是 import statsmodels 似乎可以工作并且安装了 0.12.2 版本的 statsmodles 包。但是如果没有 api，我真的无法使用 statsmodels。如果我在尝试调用 import statsmodels 时只是 statsmodels.api.OLS(y,x)，我会得到 AttributeError: module 'statsmodels' has no attribute 'api'。我在尝试 import statsmodels.api as sm 时遇到的主要错误粘贴在下面。注意：安装了所有最新的依赖项，我使用的是 python 3.8.5。
