python - 从金字塔导入 auto_arima 时出错

Question

尝试使用金字塔的 auto arima 功能，但无济于事。

导入整个类:

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

我收到错误信息:

NameError: name 'auto_arima' is not defined

好吧，那么让我们从金字塔中导入那个特定的包。

from pyramid.arima import auto_arima

--------------------------------------------------------------------------- RuntimeError Traceback (most recent call last) RuntimeError: module compiled against API version 0xb but this version of numpy is 0xa

--------------------------------------------------------------------------- ImportError Traceback (most recent call last) in () 1 #trying to import pyramid ----> 2 from pyramid.arima import auto_arima

ImportError: numpy.core.multiarray failed to import

在导入 numpy 之后，甚至只是再次运行该 block 之后，我在运行 from pyramid.arima import auto_arima 时收到此错误消息


--------------------------------------------------------------------------- ImportError Traceback (most recent call last) in () 1 #trying to import pyramid ----> 2 from pyramid import arima

ImportError: cannot import name C_Approx

Answer 1

尝试使用 pip 安装 pmdarima:

pip install pmdarima

然后在你的 python 脚本中使用:

from pmdarima.arima import auto_arima
