PyVista is a general purpose 3D visualization library used for over 2000+ open source projects for the visualization of everything from computer aided engineering and geophysics to volcanoes and digital artwork.

PyVista exposes a Pythonic API to the Visualization Toolkit (VTK) to provide tooling that is immediately usable without any prior knowledge of VTK and is being built as the 3D equivalent of Matplotlib, with plugins to Jupyter to enable visualization of 3D data using both server- and client-side rendering.

Pandas and scikit-learn have become staples in the machine learning toolkit for processing and modeling tabular data in Python. However, when data size scales up, these tools become slow or run out of memory. Ibis provides a unified, Pythonic, dataframe-like interface to 20+ execution backends, including dataframe libraries, databases, and analytics engines. Ibis enables users to leverage these powerful tools without rewriting their data engineering code (or learning SQL). IbisML extends the benefits of using Ibis to the ML workflow by letting users preprocess their data at scale on any Ibis-supported backend.

In this tutorial, you'll build an end-to-end machine learning project to predict the live win probability after each move during chess games.

Spreadsheets are one of the most common ways to share and work with data which helpfully also works great in Python! In this tutorial, we will cover some of the basics and best pratice of consuming and producing spreadsheets in Python as well as a deep dive into how to run Python directly in your spreadsheets. We will introduce and dive deep into the new Python in Excel features as well as the Anaconda Toolbox for Excel add-in.

Working with data can be challenging: it often doesn’t come in the best format for analysis, and understanding it well enough to extract insights requires both time and the skills to filter, aggregate, reshape, and visualize it. This session will equip you with the knowledge you need to effectively use pandas – a powerful library for data analysis in Python – to make this process easier.

Pandas makes it possible to work with tabular data and perform all parts of the analysis from collection and manipulation through aggregation and visualization. While most of this session focuses on pandas, during our discussion of visualization, we will also introduce at a high level Matplotlib (the library that pandas uses for its visualization features, which when used directly makes it possible to create custom layouts, add annotations, etc.) and Seaborn (another plotting library, which features additional plot types and the ability to visualize long-format data).

Scientific researchers need reproducible software environments for complex applications that can run across heterogeneous computing platforms. Modern open source tools, like pixi, provide automatic reproducibility solutions for all dependencies while providing a high level interface well suited for researchers.

This tutorial will provide a practical introduction to using pixi to easily create scientific and AI/ML environments that benefit from hardware acceleration, across multiple machines and platforms. The focus will be on applications using the PyTorch and JAX Python machine learning libraries with CUDA enabled, as well as deploying these environments to production settings in Linux container images.

Large Language Models (LLMs) have revolutionized natural language processing, but they come with limitations such as hallucinations and outdated knowledge. Retrieval-Augmented Generation (RAG) is a practical approach to mitigating these issues by integrating external knowledge retrieval into the LLM generation process.

This tutorial will introduce the core concepts of RAG, walk through its key components, and provide a hands-on session for building a complete RAG pipeline. We will also cover advanced techniques, such as hybrid search, re-ranking, ensemble retrieval, and benchmarking. By the end of this tutorial, participants will be equipped with both the theoretical understanding and practical skills needed to build robust RAG pipeline.

Ontologies provide a powerful way to structure knowledge, enable reasoning, and support more meaningful queries compared to traditional data models. Recently, interest in ontologies has resurged, driven by advancements in language models, reasoning capabilities, and the growing adoption of platforms like Palantir Foundry.

In this hands-on tutorial, participants will explore ontology development across multiple domains using a variety of Python-based tools such as rdflib, Owlready2, PySpark, Pandas, and SciPy. They will learn how ontologies facilitate semantic reasoning, improve data interoperability, and enhance query capabilities.
Additionally, attendees will build a rudimentary reasoning engine to better understand inference mechanisms.
The tutorial emphasizes practical applications and comparisons with conventional data representations, making it ideal for researchers, data engineers, and developers interested in knowledge representation and reasoning.

The advancement of AI systems necessitates the need for interpretability to address transparency, biases, risks, and regulatory compliance. The workshop teaches core techniques in interpretability, including SHAP (game-theoretic feature attribution), GINI (decision tree impurity analysis), LIME (local surrogate models), and Permutation Importance (feature shuffling), which provide global and local explanations for model decisions. With hands-on building of interpretability tools and visualization techniques, we explore how these methods enable bias detection and clinical trust in healthcare diagnostics and develop the most effective strategies in finance. These techniques are essential in building interpretable AI to address the challenges of the black-box models.

Structured Query Language (or SQL for short) is a programming language to manage data in a database system and an essential part of any data engineer’s tool kit. In this tutorial, you will learn how to use SQL to create databases, tables, insert data into them and extract, filter, join data or make calculations using queries. We will use DuckDB, a new open source embedded in-process database system that combines cutting edge database research with dataframe-inspired ease of use. DuckDB is only a pip install away (with zero dependencies), and runs right on your laptop. You will learn how to use DuckDB with your existing Python tools like Pandas, Polars, and Ibis to simplify and speed up your pipelines. Lastly, you will learn how to use SQL to create fast, interactive data visualizations, and how to teach your data how to fly and share it via the Cloud.

In this tutorial, you will learn how to integrate Large Language Models (LLMs) directly into Python programs as thoughtfully-designed core components of the program rather than bolt-on additions. This hands-on session teaches design principles and practical techniques for incorporating LLM outputs into program control flow. We will use LlamaBot, an open-source Python interface to LLMs, focusing on local execution with local and efficient models.

This tutorial will explore GPU-accelerated clustering techniques using RAPIDS cuML, optimizing algorithms like K-Means, DBSCAN, and HDBSCAN for large datasets. Traditional clustering methods struggle with scalability, but GPU acceleration significantly enhances performance and efficiency.

Participants will learn to leverage dimensionality reduction techniques (PCA, T-SNE, UMAP) for better data visualization and apply hyperparameter tuning with Optuna and cuML. The session also includes real-world applications like topic modeling in NLP and customer segmentation. By the end, attendees will be equipped to implement, optimize, and scale clustering algorithms effectively, unlocking faster and more powerful insights in machine learning workflows.

As general purpose GPU programming has risen in popularity, many Python programmers have expressed a need to use this technology in their libraries and applications. They soon realize that the GPU landscape is vast and sometimes difficult to traverse for Python users.

In this talk, I will demystify the CUDA-enabled Accelerated Python landscape, focusing on the advantages and disadvantages of popular libraries, the common performance issues encountered, and the best practices to getting the most out of your GPU. Topics include CuPy, numba, nvmath-python, cuDF, and cuML.

This talk is beginner-friendly, but even the most seasoned programmer will gain insight into the Python GPU computing landscape.

Despite its reputation for being slow, Python is the leading language of scientific computing, which generally needs large-scale (fast) computations. This is because most scientific problems can be split into "metadata bookkeeping" and "number crunching," where the latter is performed by array-oriented (vectorized) calls into precompiled routines.

This tutorial is an introduction to array-oriented programming. We'll focus on techniques that are equally useful in any array library, with a particular focus on NumPy and JAX. You'll work in groups on four class projects: Conway's Game of Life using arrays, iterative computations on arrays, just-in-time (JIT) compilation for the Mandelbrot set, and exploring data in ragged arrays.

This tutorial is an introduction to data visualization using the popular Vega-Altair Python library. Vega-Altair provides a simple and expressive API, enabling authors to rapidly create a wide range of interactive charts.

Participants will explore the fundamentals of effective chart design and gain hands-on experience building a variety of visualizations using Vega-Altair's declarative API. Furthermore, this tutorial will introduce users to advanced topics such as data transformations and interaction design. We will finish off by covering practical workflows such as integrating Vega-Altair into dashboarding systems, publishing visualizations, and creating reusable, themed charting libraries. By the end of the session, attendees will have the skills to leverage Vega-Altair for both rapid prototyping and production-ready visualizations in diverse environments
