python – 从金字塔导入auto_arima时出错

试图使用金字塔的自动arima功能,无处可去.

导入全班：

import pyramid



stepwise_fit = auto_arima(df.Weighted_Price, start_p=0, start_q=0, max_p=10, max_q=10, m=1,
                      start_P=0, seasonal=True, trace=True,
                      error_action='ignore',  # don't want to know if an order does not work
                      suppress_warnings=True,  # don't want convergence warnings
                      stepwise=True)  # set to stepwise

我收到错误消息：

NameError: name 'auto_arima' is not defined

好的,然后让我们从金字塔中导入特定的包.

from pyramid.arima import auto_arima

last) RuntimeError: module compiled against API version 0xb but this
version of numpy is 0xa

ImportError: numpy.core.multiarray failed to import

导入numpy之后,或者甚至在刚刚再次运行块之后,从pyramid.arima import auto_arima运行时出现此错误消息

————————————————————————— ImportError Traceback (most recent call

ImportError: cannot import name C_Approx

解决方法:

环境：
Windows 10
IDE：Pycharm
Python：3.6

在Anaconda中,创建一个新环境,然后运行：

pip install pyramid-arima

现在在你的python代码中,你可以使用：

来自pyramid.arima import auto_arima
