Recently I got sort of addicted to a simple-not-so-simple word game on my phone.
In this talk I'll discuss how I used Python first to cheat then to more deeply explore the space of puzzles and solutions.
Anthony Shaw is a Python advocate from Sydney, Australia. Anthony is a contributor to many open-source communities. Running and contributing to a number of popular open-source tools for DevOps, Security, Automation and Code Quality.

Anthony has been recognized for his contribution to open-source, including a Fellow of the Python Software Foundation and a member of the Apache Software Foundation.

Anthony runs a Python blog and YouTube channel and has recently published a book on the Python compiler.
In this talk you'll see an update to the Pyjion project, a JIT compiler for CPython byte-code.

This project was started 5 years ago but stopped after making no gains in performance. Recent changes to CPython have made optimisations more viable, so now it has been restarted and is showing big performance gains vs. standard CPython with 100% compatibility. Many attempts have been made to JIT compile Python in the fast and few have succeeded.

Is it worth it and what are the gains to be made? This talk will cover the design ideas of a JIT for CPython, optimisations, and future potential.
I'm tiangolo (Sebastián Ramírez), the creator of FastAPI, Typer, and other open-source tools.

I'm currently a developer at Explosion in Berlin, Germany.
If you have used CLI (Command Line Interface) applications, you are probably familiar with shell completion (TAB completion) and how much it helps.

In this talk, you'll learn how to quickly create CLI apps that have automatic shell completion with Typer (FastAPI's little sibling), by declaring standard Python type annotations in your functions.

Typer will do the heavy lifting of handling shell completion for all the major shells, auto-documentation of your CLI, and data validation based on your type annotations.

You can start with just a simple script for yourself, in minutes. And also grow as big as you need, to create complex CLI apps with multiple levels of sub-command groups and many other features.

All by writing minimal code, based on standard type annotations, with autocompletion in your editor, and an intuitive design based on FastAPI.
Mariatta is a Python Core Developer, Staff Software Engineer at Uplight, and the Vancouver PyLadies co-organizer, and one of the founding members of the PyCascades conference.

She moved to Canada almost two decades ago, and now lives in Vancouver with her husband and two children. In her free time, she contributes to open source, builds GitHub bots, and fixes typos.
I consider myself relatively new to the open-source world; my first open-source contribution was in 2016. Since then, I've continued to actively contribute to open source and specifically to core Python and Python libraries.

Pretty soon I found myself being given commit rights to other people's open-source projects. It's been quite a journey. Being a new open-source contributor has its own challenges, and being a new open-source maintainer brings another set of unique challenges.

In this talk, I will share my journey and the things I've learned along the way, and some advice for other aspiring open source maintainers and contributors.

Machine Learning (ML) adoption in the enterprise requires simpler and more efficient software infrastructure. Model scoring, the process of obtaining prediction from a trained model over new data, is a primary contributor to infrastructure complexity and cost, as models are trained once but used many times.

Hummingbird is a novel approach to model scoring, which compiles featurization operators and traditional ML models (e.g., decision trees) into a small set of tensor operations. This approach inherently reduces infrastructure complexity and directly leverages existing investments in Neural Networks' compilers and runtimes to generate efficient computations for both CPU and hardware accelerators.

Hummingbird performance are competitive and even outperforms hand-crafted kernels while enabling seamless end-to-end acceleration of ML pipelines.

Hummingbird is open source, part of the PyTorch Ecosystem, and someone even mentioned it as one of the top 10 Python libraries of 2020!

Aspect-based Sentiment Analysis is a challenging task of text analysis in e-Commerce. It researches and develops related ideas for text Sentiment Analysis to obtain Sentiment Analysis for each aspect in a text.

The proposed approach provides algorithms for aspects spotting based on semantic analysis of a text and estimating sentiment for the context of the aspects. Approach capabilities are perfectly matched for goods review analysis. In the presentation, it will be considered the solution based on BERT transformation and the development of a service for deploying the resulting model.

Programming languages with dynamic type systems as well as freeform document databases give us a big productivity boost early on in the project.

On the other hand, strong static type systems and relational databases protect us against an entire category of programming mistakes, and aid in code maintenance by helping IDEs auto-complete, jump to definition, refactor, and so on.

Is there a workable compromise? Can we somehow reap the benefits of both? Let's find out!
MinJae (a.k.a mingrammer) is the creator of Diagrams.
He has used Python for a long time to build automation and productivity tools.
Diagrams let you draw the cloud system architecture in Python code. It was born for prototyping a new system architecture design without any design tools.

In this talk, I will introduce the Diagrams as a whole and share why I made the Diagrams, and how it was designed and built.
Thomas is the CEO at PyMC Labs (www.pymc-labs.io). Prior to that Thomas was the VP of Data Science at Quantopian, where he used probabilistic programming and machine learning to help build the world's first crowdsourced hedge fund.

He is an author of the popular PyMC3 package — a probabilistic programming framework written in Python. He holds a PhD from Brown University.
Bayesian modeling is an extremely powerful tool in solving data science problems across different domains. And while user-friendly modeling packages like PyMC3 exist, understanding the underlying concepts still provides a challenge for many newcomers. The main reason is that usually, statistics is taught by statisticians who provide formulas with little regard for intuition.

In this talk I will take the opposite approach: throw all math out the window and explain the underlying concepts in an intuitive way.
Emeli is a Co-founder and CTO at Evidently AI, a startup developing tools to analyze and monitor the performance of machine learning models.

ML-based services are different from traditional software applications. Once they are in production, we have to keep an eye not only on the code, but also on the data and model performance.

In this talk, I will share what new failure modes to prepare for, and how to set up model monitoring using open-source tools.
Artem develops projects on ML implementation in operational audit processes to optimize them and improve their user-friendliness. The key projects at Sberbank are the ones aimed to develop personalized recommendations for employees (from training to recommendations not to make mistakes).

Passionate about recommendations, applies them everywhere.
Are you tired of counting ratings in your recommendation systems yet? I am, so I started looking for other options in building recommendation systems.

We need to take a step away from "dry" ratings and try to understand the surrounding contexts. This type of recommendation changes the rating calculation from the user * item> rating formula to the user * item * context> rating formula, it seems very simple, but it is not!

How to do this and where to start? Let's work together along the path of adding context to recommendations. In my practice, adding context has helped increase conversions, but what will you get?
Alejandro is the Chief Scientist at the Institute for Ethical AI & Machine Learning, where he leads the development of industry standards on machine learning explainability, adversarial robustness and differential privacy.

He has a strong track record building cross-functional departments of software engineers from scratch, and leading the delivery of large-scale machine learning systems across the financial, insurance, legal, transport, manufacturing and construction sectors (in Europe, US and Latin America).
The lifecycle of a machine learning model only begins once it's in production. In this talk we provide a practical deep dive on best practices, principles, patterns and techniques around production monitoring of machine learning models. We will cover standard microservice monitoring techniques applied into deployed machine learning models, as well as more advanced paradigms to monitor machine learning models through concept drift, outlier detector and explainability.

We'll dive into a hands-on example, where we will train an image classification machine learning model from scratch, deploy it as a microservice in Kubernetes, and introduce advanced monitoring components as architectural patterns with hands-on examples. These monitoring techniques will include AI Explainers, Outlier Detectors, Concept Drift detectors and Adversarial Detectors.

We will also be understanding high level architectural patterns that abstract these complex and advanced monitoring techniques into infrastructural components that will enable for scale, introducing the standardised interfaces required for us to enable monitoring across hundreds or thousands of heterogeneous machine learning models.

The strengths and weaknesses of Python lend themselves to a different style of object-oriented programming.

By accepting several constraints on how we design and implement classes, we make our code more robust, more testable, and easier to adapt to changing circumstances
I became a programmer, driven by a childhood dream of making video games.

During a long journey through software development, I made my bones in the wasteland of system, web and desktop applications. My dream came true three years ago, when I joined Wargaming and became part of the awesome team behind the legendary World of Tanks game. I am currently developing the gameplay logic for it.
Mid-80s. The game industry was relaunched with the release of Nintendo Entertainment System (aka "Dendy"), the 8-bit console which defined gaming for the decade to follow.
For its time, it was quite a piece of hardware, featuring the legendary 6502 CPU, 2KiB RAM, and a "GPU" capable of rendering a bunch of sprites on a 240x256 pixels TV screen.
How you ever make a game with that?! Back in time, it was raw assembly and thinking by hex numbers.

In this talk, I'll show you how the NES worked and how games for it were made.But to keep your sanity in place, there'll be almost no assembly. Instead, you will learn how to make your own compiled programming language in Python, to make the gamedev fun again!

I'll show how to define the grammar, parse it, translate the high-level constructs into NES-compatible machine code and build the final executable which goes into the ROM.

There are a lot of myths and misconceptions around applying best practices in the field of machine learning and data science. Also there is a big difference between one team of two DS who uses Git plus DVC and several teams of developers with diverse backgrounds and expertise.

Why and how to adopt best practices for machine learning projects. How to automate continuous integration and ML-models delivery, to get better codebase structure and to do data management. Why to do code review of experimental code. In this talk I will share our experience.
The speakers will discuss what they have discovered in the Python ecosystem recently and how it has improved their lives, as well as what announcements they are looking forward to and enthusiastic about.

What about you? What are you already using in production, and what else are you looking forward to on the next project? Join our chat, share your discoveries and achievements in Python.

The session is in Russian.
Each IT team accumulates its own life hacks and tricks, finds its favorite tools and processes. The speakers will talk about how their teams are solving typical problems faced by developers.

How do you do code review? How do you decide if you should start using FastAPI in your next project, or try Django for now? How do you document your code? We will ask our experts what they are doing and share our stories and findings in the chat.
I have more than 12 years of Python experience behind me, most of which was devoted to Python and preaching good coding practices.

From monolithic accounting systems to authentication microservices, it was a rough ride littered with rotting husks of legacy codebases. This path allowed me to accumulate bumps and some good advice which I shared previously on conferences and meetups. But there is always more to tell and to share.
