In this workshop, we will use transfer learning to retrain a ResNet model using PyTorch to recognize dog breeds using the Stanford Dog dataset. The training jobs will be submitted to the Azure Machine Learning service to run on Azure compute. Once the model is trained, we will deploy it as a web service and send a few pictures to test! Along the way, you’ll use Azure Notebooks, Visual Studio Code, and Azure Machine Learning service. Learning objectives: - Train models using Jupyter Notebooks and PyTorch - Deploy models as web services and test - Learn how to use Azure and Visual Studio Code

AsyncIO is a powerful mechanism for building high-performance services, but it has long been thought of as “too complicated”. But it’s easier than you might think, and with Python 3.7, it’s easier than ever to get started using just the standard library! We'll cover the basics of AsyncIO, take a look at the latest features in 3.7, build friendly and expressive APIs, analyze best practices for third-party libraries, and discuss integrating async code with synchronous libraries and codebases.

In this workshop, we will start with a bare-bones Django application. We’ll talk about 12 Factor Django apps and why you’d want one, then configure our application for deploy on Heroku. We’ll add a custom domain name, configure CI and Github Integration for our project. Next, we’ll add some human complexity and talk about how to collaborate with others and how to control and share access on Heroku. Then, we’ll walk through some more complex code examples and how to get them running on Heroku. Come prepared with: - Python 3.7 installed - Git installed - Django pip installed

Audience Level: Beginner to Intermediate Even if you are a seasoned Python wizard it takes some effort to get your bearings when working with geographical data.  In this workshop, we'll start with some beginner projects to build geospatial applications. - How to identify the location of an image file with PIL - How to find places on a map with NLTK - How to read/write geospatial file types with tools like geopandas - How to visualize point clouds from GPS traces or LiDAR data with PPTK - How to store and query vector tiles with XYZ By the end of our time together you will have gone from Hello World to having a roadmap for where to learn more about geospatial tools and techniques.

Support for Python on Google Cloud has never been better. Join us for a tour of Python runtimes, services and client libraries, including App Engine, Cloud Functions, Cloud Run, and more. We'll also discuss tools for monitoring and debugging your Python application, and best practices for using Python on Google Cloud. This is explicitly a sponsored product tour - we promise to focus on solving real problems with these tools and to include lots of interactive hands-on demos and example code.

"Audience Level: Beginning to Intermediate Not all APIs offer a GraphQL endpoint, but it is a wonderful way to consume and explore an API. We will cover creating a GraphQL endpoint on top of a RESTful API using Flask, Graphene, and Square APIs. Through this workshop you’ll learn about Graphql: How to create schemas using Graphene When to use Queries vs Mutations What a Resolver is and how to construct them"

In this workshop, we'll give a technical introduction to the various techniques that PyTorch uses to scale a Pythonic machine learning workflow from research to production. We'll talk about how we use Python's dynamism and reflection capabilities to build a high-performance compiler infrastructure for machine learning. After, we'll demo how you can use these tools to ship a machine translation model to production today!

Abstract: Continuing with tradition, our sponsor workshop session features three awesome half-hour Python tech talks at they relate to Google. Hear about Python tools we’ve built in-house, using Python with Google developer tools to build your web & mobile applications with, or best practices on how we use Python internally at Google. You’re invited to stop by and hear from a cadre of world-class Google engineers from around the world! :-) 1- What’s New with TensorFlow 2.0 Speaker: Brad Miro, Google, New York Abstract Learn about the updates being made to TensorFlow in its 2.0 version. We’ll give an overview of what’s available in the new version as well as do a deep dive into an example using its central high-level API, Keras. You’ll walk away with a better understanding of how you can get started building machine learning models in Python with TensorFlow 2.0 as well as the other exciting available features! Speaker Bio Brad is passionate about educating the world about artificial intelligence both by empowering developers and improving societal understanding. He is currently a Developer Programs Engineer at Google where he specializes in machine learning and big data solutions. Outside of work, Brad can be found singing, skiing, playing board games and locating the best restaurants in NYC. 2 - Extreme Python Operator Overloading using AST Manipulation Speaker: Brian Lee, Google, Cambridge Abstract Python's `__add__, __iter__, __getitem__, __enter__`, and other magic "dunder" methods grant extraordinary flexibility in constructing new libraries and domain-specific languages on top of Python. It's very easy to create new context managers, overload object slicing, implement custom initializers/destructors, and more. With this power, library authors have wrapped C libraries like libxml2 (lxml) or blas/lapack (NumPy) with more Pythonic APIs. However, there are core Python features and syntax that can't be overridden, like for/while loops, conditionals, and built-ins like zip and enumerate. It's not even obvious how these should be defined, since they can't be defined on a per-class basis like every other dunder method. In this talk, we'll discuss how to use AST manipulation to override the behavior of Python control flow and other builtins, and why one might want to do such a thing. These AST manipulation utilities are used by TensorFlow's AutoGraph functionality, which we'll briefly discuss. Speaker Bio Brian is a Pythonista of 8 years and works at Google on TensorFlow AutoGraph and Minigo, among other things. 3 - Ask a Google Engineer Anything Moderator: Wesley Chun, Google, Sunnyvale Abstract This is an "AMA" session, giving all of you a chance to ask a Google engineer burning questions on your minds. That doesn’t mean we’ll be able to answer, however we’ll do our best! First popularized at OSCON back in 2010 then debuting at PyCon in 2013, these sessions are useful in helping developers become familiar with Alphabet, Googlers, their roles, products, and technologies, as well as be able answer technical questions that have them curious. It's been over 6 years since that first one at PyCon so it's about that time again. For half-hour, we’ll corral as many Googlers as we can get at PyCon to participate in this informative yet entertaining Q&A session. Speaker Bio WESLEY CHUN (@wescpy) is the author of Prentice Hall's bestselling "Core Python" (corepython.com) series, co-author of "Python Web Development with Django" (withdjango.com), and has written for Linux Journal, CNET, and InformIT. In addition to being an engineer at Google and one of the hosts of the G Suite Dev Show (goo.gl/JpBQ40), he runs CyberWeb (cyberwebconsulting.com), specializing in Python training. Wesley was one of the original Yahoo!Mail engineers, holds degrees in CS, Math, and Music from the University of California, and is a Fellow of the Python Software Foundation.

We live in a world of ever-increasing data, complexity, and computer intelligence. We are constantly making decisions on how to make software processes faster, more efficient, or cheaper to operate. There is a lot of misguided wisdom, folklore, and superstition around software performance that can be as much help as hindrance. In our tutorial, we'll present some fundamental rules of software performance as a set of physical, intuitive "laws", with illustrative examples. Our goal is for every audience member to leave with enough of a grounding in these underlying laws to make rational performance decisions when selecting their programming tools, algorithms, and hardware. Audience: This tutorial is intended for audiences without a computer science background, or those with a computer science background who are interested in discussing and explaining performance concepts to those without it. Some programming experience in Python will be helpful, as will access to the tutorial notebooks and the ability to run them live. Mathematics will be discussed, but will not be required beyond a high school level to understand and engage.

Instagram employs Python in one of the world's largest settings, using it to serve 1 billion monthly active users. We chose Python because of its reputation for simplicity and practicality, which aligns well with our philosophy of “do the simple thing first.” Come learn about the challenges, learnings, and techniques used at Instagram to maintain and advance our million-LOC, thousand endpoint Django application. We will discuss how we empower engineers to build quickly while managing complexity and maintaining a high-quality codebase. Topics may include AST-based lint frameworks, tools for large-scale codebase refactors, adopting Python type annotations, types for Django HTTP APIs, safe hot-reloading of Python code, and more. This will be an informal setting; if you've ever wondered how Python works at scale, this is your chance to ask!

In this workshop, we discuss how we develop and maintain our open-source Python tools at Slack. We’ll also teach you how to build your own useful Slack bot and leave plenty of time for Q&A. Beginners are welcome! Developers with Slack experience will learn about recently released features and tools and have face time with the Dev Rel team.

Location matters in every problem you are trying to solve, and a geographic approach is often crucial to extracting meaning from data. In this workshop, learn about ArcGIS Notebooks, a built-in Python-scripting environment in web GIS (geographic information systems) that puts the power of spatial algorithms and analysis tools into the hands of problem solvers. With ArcGIS Notebooks, you can find and prepare data, develop iterative analysis workflows, train and optimize models, build information products, share results, and collaborate with the rest of your organization. You'll learn how: - Spatial can play a role in your data science notebooks - Ready-to-use datasets can augment your analysis - To visualize your analysis in beautiful maps - Train and do inferencing with a deep learning model on geospatial data

In banking we often find ourselves wanting to predict an outcome or variable for which no labels exist to indicate ground truth. Does this mean we cannot apply supervised machine learning techniques? No! In this talk, you will learn how we created proxy labels for recurrent transactions using python and Apache Spark. Some examples of recurring transactions are Netflix and Spotify subscriptions. The best part about the approach we used is that it did not require paying humans to manually create labels, saving both time and money while increasing accuracy since it bypasses human error. Because of the robustness of the proxy labels created, we were able to improve upon a previously rule-based process for determining recurring transactions. This ensures that customers do not experience interruption when their card is replaced and they are notified when subscription costs increase significantly, among many other benefits. ### Abstract #### Audience The target audience is machine learning engineers, data scientists, and finance/banking folks. However, anyone with an interest in machine learning or banking will benefit from the talk. #### Objectives The audience will come away with an understanding of an approach to create labels for unlabeled data and get exposure to a situation in which python and Apache Spark provide business value. #### Notes The project has evolved greatly since this article was written, but still provides useful context for understanding value proposition of predicting recurring transactions. https://finovate.com/feature-friday-capital-one-helps-users-reset-recurring-charges-after-card-reissue/
