python - 导入 statsmodel.api 时出错。无法导入 specfun

Question

我已经为 python 导入了 statsmodel.api 1000 次。刚开始在导入时出现随机错误。有人有这个错误吗？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`

我遇到了与 scipy 0.15.1 中的错误或丢失 scipy.special.specfun 有关的相同问题。将我的 scipy 版本恢复到 0.14.0 是一种变通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，从 binstar 上的其他包安装也可以。
