A recent eBay Tech Blog article presented the Unified AI platform called Krylov. In this article, we show how Krylov users interact with the platform to build and manage powerful workflows in a pythonic and efficient way.

In this tutorial, you’ll learn how to setup your NVIDIA Jetson Nano, run several object detection examples and code your own real-time object detection program in Python from a live camera feed.  Several DNN models are supported, including SSD-Mobilenet and SSD-Inception, which are pre-trained on the 90-class MS COCO dataset and can detect a variety of objects.  

This post shows how to create a simple application to track the Coronavirus spreading using Python. At this end of this tutorial we will get a html page that shows a map with infected locations, including a slider to track the virus spreading based on date.

A follow up to a previous post we wrote in the midst of our Python 2 to 3 project, describing our strategy and rollout plan. Now that we’ve fully rolled out to Python 3 (as of early September), we wanted to talk about how our production deployment went and reflect a little on the project.

SciPy is an open-source scientific computing library for the Python programming language. Since its initial release in 2001, SciPy has become a de facto standard for leveraging scientific algorithms in Python, with over 600 unique code contributors, thousands of dependent packages, over 100,000 dependent repositories and millions of downloads per year. In this work, we provide an overview of the capabilities and development practices of SciPy 1.0 and highlight some recent technical developments.
