BentoML-0.8.1

on GitHub

What's New?

• Service API Input/Output adapter #783 #784 #789, by @bojiang

  • A new API for defining service input and output data types and configs
  • The new InputAdapter is essentially the API Handler concept in BentoML prior to version 0.8.x release
  • The old API Handler syntax is being deprecated, it will continue to be supported until version 1.0
  • The main motivation for this change, is to enable us to build features such as new API output types(such as file/image as service output), add gRPC support, better OpenAPI support, and more performance optimizations in online serving down the line

• Model server docker image build improvements #761

  • Reduced docker build time by using a pre-built BentoML model server docker image as the base image
  • Removed the dependency on apt-get and conda from the custom docker base image
  • Added alpine based docker image for model server deployment

• Improved Image Input handling:

  • Add micro-batching support for ImageInput (former ImageHandler) #717, by @bojiang
  • Add support for using a list of images as input from CLI prediction run #731, by @bojiang
  • In the new Input Adapter API introduced in 0.8.0, the LegacyImageInput is identical to the previous ImageHandler
  • The new ImageInput works only for single image input, unlike the old ImageHandler
  • For users using the old ImageHandler, we recommend migrating to the new ImageInput if it is only used to handle single image input
  • For users using ImageHanlder for multiple images input, wait until the MultiImageInput is added, which will be a separate input adapter type

• Added CORS support for AWS Lambda serving #752, by @omrihar
