fbprophet export ds，yhat对csv的预测

Question

我正在使用sub-daily data上的先知教程。我也使用默认的example_yosemite_temps.csv。我试图将ds和yhat预测数据导出到CSV文件。以下是我到目前为止的情况。出于某种原因，只有标题会保存到CSV。

如何将所有ds数据放入一列，将所有数据放入另一列？

import pandas as pd
import numpy as np
from fbprophet import Prophet
import csv

df = pd.read_csv('example_yosemite_temps.csv')
m = Prophet(changepoint_prior_scale=0.01).fit(df)
future = m.make_future_dataframe(periods=10, freq='H')
forecast = m.predict(future)

timestamp = forecast[['ds']]
tempFuture = forecast[['yhat']]

#print(timestamp)
#print(tempFuture)


rows = zip(timestamp,tempFuture)

with open('predict.csv', "w") as f:
    writer = csv.writer(f)
    for row in rows:
        writer.writerow(row)

Answer 1

找到解决方案：

forecast.to_csv('PredictOutput.csv')
