1.?"ImportError: No module named" when trying to run Python script

notebook不知道m(xù)odule的路徑在哪，默認(rèn)只知道current path

先找到包所在位置

pip show --verbose pandas

再告訴notebook

import sys

sys.path.append('/usr/local/lib/python2.7/dist-packages')

2. ?安裝分解時(shí)間序列用到的包

pip install statsmodels

3.?AttributeError: 'Index' object has no attribute 'inferred_freq'

seasonal_decompose()對(duì)pandas Series需要是datetime

import pandas as pd

from pandas import Series

from matplotlib import pyplot

from statsmodels.tsa.seasonal import seasonal_decompose

df = pd.read_csv('data.csv', header=0)

df.Date = pd.to_datetime(df.Date,errors='coerce')

df = df.set_index('Date')

result = seasonal_decompose(df, model='mutiplicative',freq=7)

result.plot()

pyplot.show()

4. notebook顯示圖片太小，變大

import matplotlib.pyplot as plt

fig_size = [20, 9]

plt.rcParams["figure.figsize"] = fig_size
