【问题描述】：

我已经完成了这个答案 While importing auto_arima from pmdarima: ERROR : cannot import name 'factorial' from 'scipy.misc' 但无法修复错误，我不明白如何使用开发者版本。还有其他方法可以应用季节性 ARIMA 模型吗？

import statsmodels.api as sm
mod = sm.tsa.statespace.SARIMAX(train_weekly.Price,
                                order=(1, 0, 0),
                                seasonal_order=(1, 1, 0, 12),
                                enforce_stationarity=False,
                                enforce_invertibility=False)

results = mod.fit()
print(results.summary().tables[0])
print(results.summary().tables[1])

下面是输出

ImportError                               Traceback (most recent call last)

      5                                 enforce_stationarity=False,

我只想使用季节性 ARIMA，如果有其他方法请帮助我。谢谢。

This issue is solved temporarily.

【解决方案1】：

似乎scipy 模块的版本不匹配。尝试降级 scipy 模块。

在windows中以管理模式执行以下命令，

pip3 install --user scipy==1.2.0

如果您使用的是 Linux，

python3.6 -m pip install scipy==1.2 --upgrade
