module 'pandas' has no attribute 'rolling_mean'
提问by Pruce Uchiha
I am trying to build a ARIMA for anomaly detection. I need to find the moving average of the time series graph I am trying to use pandas 0.23 for this
我正在尝试构建一个用于异常检测的 ARIMA。我需要找到时间序列图的移动平均值我正在尝试为此使用 pandas 0.23
import pandas as pd
import numpy as np
from statsmodels.tsa.stattools import adfuller
import matplotlib.pylab as plt
from matplotlib.pylab import rcParams
rcParams['figure.figsize'] = 15, 6
dateparse = lambda dates: pd.datetime.strptime(dates, '%Y-%m')
data = pd.read_csv('AirPassengers.csv', parse_dates=['Month'], index_col='Month',date_parser=dateparse)
data.index
ts = data['#Passengers']
ts.head(10)
plt.plot(ts)
ts_log = np.log(ts)
plt.plot(ts_log)
moving_avg = pd.rolling_mean(ts_log,12) # here is the error
pd.rolling_mean
plt.plot(ts_log)
plt.plot(moving_avg, color='red')
error:Traceback (most recent call last): File "C:\Program Files\Python36\lastmainprogram.py", line 74, in moving_avg = pd.rolling_mean(ts_log,12) AttributeError: module 'pandas' has no attribute 'rolling_mean'

I believe need change:
我相信需要改变：
moving_avg = pd.rolling_mean(ts_log,12)
to:
到：
moving_avg = ts_log.rolling(12).mean()
because old pandas version code below pandas 0.18.0
因为下面的旧熊猫版本代码 pandas 0.18.0

Change:
改变：
moving_avg = pd.rolling_mean(ts_log,12)
to:
到：
rolmean = pd.Series(timeseries).rolling(window=12).mean()
rolstd = pd.Series(timeseries).rolling(window=12).std()

You will need this in your detection so you can add.
您将在检测中需要它，以便您可以添加。
moving_std = ts_log.rolling(12).std()
