从金字塔导入 auto_arima 时出错

Question

尝试使用金字塔的自动 arima 功能，但没有成功。

导入整个class:

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，甚至只是再次运行块之后，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

尝试卸载 numpy 并安装最新版本。
尝试从 Anaconda 安装 pyramid-arima。

Answer 2

使用：

pip install pyramid-arima

您安装了不是您要找的网络框架金字塔。

Answer 3

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

现在在您的 python 代码中，您可以使用：

from pyramid.arima import auto_arima

Answer 4

尝试使用 pip 安装 pmdarima：

pip install pmdarima

然后在您的 python 脚本中使用：

from pmdarima.arima import auto_arima

Answer 5

这对我有用：（Anaconda 提示）

$ conda create -n pmdissue23 --yes --quiet python=3.5 numpy scipy scikit-learn statsmodels
activate pmdissue23
(pmdissue23) $ pip install pmdarima

在 anaconda 导航器中，

from pmdarima import auto_arima
