Question

我已经回答了这个问题 While importing auto_arima from pmdarima: ERROR : cannot import name 'factorial' from 'scipy.misc' 但无法解决该错误，我不知道如何使用开发人员版本。还有其他应用季节性ARIMA模型的方法吗？

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])

以下是输出

ImportError: cannot import name 'factorial'

我只想使用季节性ARIMA，如果还有其他方法，请帮助我。谢谢。

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

使用statsmodels时如何解决此错误“ ImportError：无法导入名称'factorial'”？
