Welcome to the sktime tutorial at ODSC 2024

This tutorial is about sktime - a unified framework for machine learning with time series. sktime contains algorithms and tools for building, applying, evaluating modular pipelines and composites for a variety of time series learning tasks, including forecasting, classification, regression.

sktime is easily extensible by anyone, and interoperable with the python data science stack.

This tutorial presents an up-to-date overview of sktime; an introduction to forecasting with advanced features including hierarchical and probabilistic forecasting, feature engineering, pipelines; handling deep learning and foundation models; anomaly, changepoint detection and segmentation with sktimeand skchange; creating sktime compatible components or packages, and marketplace features.

🚀 How to get started

In the tutorial, we will move through notebooks section by section.

You have different options how to run the tutorial notebooks:

• Run the notebooks in the cloud on Binder - for this you don't have to install anything!
  • this will not install heavy dependencies such as deep learning or foundation models
• Run the notebooks on your machine. Clone this repository, get conda, install the required packages in an environment, and open the notebooks with that environment. For detail instructions, see below. For troubleshooting, see sktime's more detailed installation instructions.
• or, use python venv, and/or an editable install of this repo as a package. Instructions below.

Please let us know on the sktime discord if you have any issues during the conference, or join to ask for help anytime.

💡 Description

TODO

sktime is developed by an open community, with aims of ecosystem integration in a neutral, charitable space. We welcome contributions and seek to provides opportunity for anyone worldwide.

We invite anyone to get involved as a developer, user, supporter (or any combination of these).

Installation instructions for local use

To run the notebooks locally, you will need:

• a local repository clone
• a python environment with required packages installed
• a jupyter notebook viewer using the kernel with that environment

Below instructions explain how to create a local clone, and how to install a suitable python environment.

Then, in your notebook viewer, open the respective notebook file, and select a kernel using the environment (how to do this depends on your notebook viewer - if you do not have a notebook viewer set up, we recommend to use binder).

Requirement files

There are two requirements files, since installing dependencies for foundation models takes long due to large package sizes. During the live tutorial, we recommend using binder for the latter to avoid long download and install times.

• requirements_lite.txt for "lightweight" packages used in notebooks 0-2
• requirements_dl.txt for deep learning and foundation models, notebook 3
• the demo package from notebook 4 can be installed directly

Cloning the repository

To clone the repository locally:

git clone https://github.com/sktime/sktime-tutorial-ODSC-Europe-2024

Open a console and navigate to the root of the repository clone.

Using conda env

1. Create a python virtual environment: conda create -y -n sktime_odsc python=3.12
2. Activate your environment: conda activate sktime_odsc
3. Install required packages: pip install -r requirements_lite.txt
4. If using jupyter: make the environment available in jupyter: python -m ipykernel install --user --name=sktime_odsc

Using python venv

1. Create a python virtual environment: python -m venv sktime_odsc
2. Activate your environment:

• source sktime_odsc/bin/activate for Linux
• sktime_odsc/Scripts/activate for Windows

3. Install the requirements: pip install -r requirements_lite
4. If using jupyter: make the environment available in jupyter: python -m ipykernel install --user --name=sktime_odsc

Installing the example package

To install the example package, from the repository root, type

pip install -e ./example_package

The option -e ensures that the install is editable, i.e., changes to the package will be directly reflected in the environment after a kernel restart.
