Integrate with Prophet¶

Facebook Prophet is a fast forecasting procedure for time series (calendar) data that provides complete automated forecasts that can be further tuned by hand.

Start logging¶

Connect Comet to your existing code by adding in a simple Comet Experiment.

Add the following lines of code to your script or notebook:

import comet_ml

import pandas as pd
from prophet import Prophet

experiment = comet_ml.Experiment(
    api_key="<Your API Key>",
    project_name="<Your Project Name>"
)

df = pd.read_csv("example_wp_log_peyton_manning.csv")

m = Prophet()
m.fit(df)
# Your training code

Log automatically¶

After an Experiment has been created, Comet automatically logs the following Prophet items, by default, with no additional configuration

• Hyperparameters
• Model
• Figures

You can easily turn the automatic logging on and off for any or all items. See Configure Comet for Prophet for more details.

End-to-end example¶

Following is a basic example of using Comet with Prophet.

If you can't wait, check out the results of this example Prophet experiment for a preview of what's to come.

Install dependencies¶

pip install comet_ml prophet plotly

Run the example¶

import comet_ml

import os
import pandas as pd
from prophet import Prophet
from prophet.diagnostics import cross_validation
from prophet.plot import plot_cross_validation_metric

comet_ml.init(project_name="comet-example-prophet")
experiment = comet_ml.Experiment()

# You will need to download this file from
# https://raw.githubusercontent.com/facebook/prophet/main/examples/example_wp_log_peyton_manning.csv
df = pd.read_csv("./example_wp_log_peyton_manning.csv")

model = Prophet()
model.fit(df)

future = model.make_future_dataframe(periods=365)
forecast = model.predict(future)

df_cv = cross_validation(
    model, initial="730 days", period="180 days", horizon="365 days"
)
plot_cross_validation_metric(df_cv, "mse")

Try it out!¶

Don't just take our word for it, try it out for yourself.

Configure Comet for Prophet¶

You can control each of these by setting the Experiment argument to False or the config variable to 0.
