Project Description


Facebook Prophet is an open-source software library developed by Facebook’s Core Data Science team that is designed for forecasting time series data. It is based on a decomposable time series model that allows for easy modeling of trends and seasonality, and it includes many other features that make it easy to use and customize.

Some of the key features of Facebook Prophet include:

  • Simple API: Prophet has a simple and intuitive API that allows you to quickly fit and forecast time series models.
  • Automatic trend and seasonality fitting: Prophet can automatically fit trend and seasonality models to your data, making it easy to build high-quality forecasts.
  • Handling missing data: Prophet includes tools for handling missing data and handling outliers in your time series data.
  • Customizability: Prophet allows you to customize many aspects of the forecasting model, including the trend and seasonality models, the regression model, and the forecast horizon.

Overall, Facebook Prophet is a powerful and easy-to-use tool for forecasting time series data. If you are working with time series data and need to build forecasts, you may want to consider using Prophet.

Troubleshooting Facebook Prophet with the Lightrun Developer Observability Platform


Getting a sense of what’s actually happening inside a live application is a frustrating experience, one that relies mostly on querying and observing whatever logs were written during development.
Lightrun is a Developer Observability Platform, allowing developers to add telemetry to live applications in real-time, on-demand, and right from the IDE.
  • Instantly add logs to, set metrics in, and take snapshots of live applications
  • Insights delivered straight to your IDE or CLI
  • Works where you do: dev, QA, staging, CI/CD, and production

The following issues are the most popular issues regarding this project:

Pip install error ModuleNotFoundError: No module named ‘pystan’


If you are seeing a ModuleNotFoundError: No module named 'pystan' error while trying to install Facebook Prophet via pip, it means that the pystan module is not installed on your system, and therefore it cannot be imported. pystan is a Python module that is required by Prophet for some of its functionality.

To fix this error, you will need to install pystan by running the following command:

pip install pystan

This should install the pystan module and allow you to successfully install Facebook Prophet.

If you are still having trouble after installing pystan, you may want to try installing Prophet using a different method, such as by cloning the repository from GitHub and installing it manually. You can find more information on installing Prophet in the documentation at the following link:
