     Happy to invite you to the Gradio Blocks Party - a community event in which we will setup spaces for models using the new Gradio Blocks feature. Blocks allows you to build web-based demos in a flexible way using the Gradio library. The event will take place from May 11th to 31st. We will be organizing this event on github and the huggingface discord channel.

+     Gradio is a Python library that allows you to quickly build web-based machine learning demos, data science dashboards, or other kinds of web apps, entirely in Python. These web apps can be launched from wherever you use Python (jupyter notebooks, colab notebooks, Python terminal, etc.) and shared with anyone instantly using Gradio's auto-generated share links. To learn more about Gradio see the Get Started Guide: https://gradio.app/getting_started/
