fbprophet安装好后测试代码
import pandas as pd
import numpy as np
from fbprophet import Prophet
import matplotlib.pyplot as plt
# 数据文件请从github上的Prophet项目下载，并放在代码的对应目录
df = pd.read_csv('data.csv')
df['y'] = np.log(df['y'])
print (df.tail())
# 定义模型
m = Prophet()
# 训练模型
m.fit(df)
# 构建预测集,预测未来一年的涨势
future = m.make_future_dataframe(periods=365)
print (future.tail())
# 进行预测
forecast = m.predict(future)
print (forecast.tail(10))
forecast[['ds', 'yhat', 'yhat_lower', 'yhat_upper']].tail(10)
m.plot(forecast)
