flytekit.deck.Deck

class flytekit.deck.Deck(name, html='')

Deck enable users to get customizable and default visibility into their tasks.

Deck contains a list of renderers (FrameRenderer, MarkdownRenderer) that can generate a html file. For example, FrameRenderer can render a DataFrame as an HTML table, MarkdownRenderer can convert Markdown string to HTML

Flyte context saves a list of deck objects, and we use renderers in those decks to render the data and create an HTML file when those tasks are executed

Each task has a least three decks (input, output, default). Input/output decks are used to render tasks’ input/output data, and the default deck is used to render line plots, scatter plots or Markdown text. In addition, users can create new decks to render their data with custom renderers.

This feature is in beta.
