导入 statsmodel.api 时出错。无法导入specfun

Question

我已经为 python 导入 statsmodel.api 1000 次。刚刚开始在导入时出现随机错误。有人遇到过这个错误吗？代码如下。

我使用的是 Windows，我的 python 是通过 conda 包更新的。

谢谢大家。

`import statsmodels.api as sm`

Answer 1

scipy.special.specfun我遇到了与 scipy 0.15.1 中的错误或缺失相关的相同问题。将我的 scipy 版本恢复到 0.14.0 是一种解决方法并解决了我的问题。使用 conda，您可以恢复使用 conda install scipy=0.14.0 如果需要 0.15.1，则从 binstar 上的其他软件包安装也可以。
