PySDK 0.9.1

Release Date: 08/04/2023

IMPORTANT: This release has critical bug fixes and incompatible changes with version 0.9.0. It is strongly recommended to upgrade from version 0.9.0 to version 0.9.1.

New Features and Modifications

  1. AI models of YOLOv8 family are redesigned to improve performance.

    New YOLOv8 models in the DeGirum public cloud zoo are incompatible with PySDK version 0.9.0, so in order to use YOLOv8 models you need to upgrade to version 0.9.1.

  2. Inference timeout handling is improved.

    • HTTP transactions of AI server with the cloud zoo had infinite timeouts in previous PySDK versions. This can lead to arbitrary long delays in case of poor connection between AI server and cloud zoo. In new version all such HTTP transactions now have finite timeouts.

    • Model-specific inference timeout is now passed to the cloud server, so the cloud server uses it instead of generic 180 second timeout. This greatly improves the cloud inference responsiveness.

Bug Fixes

  1. The following error message appears when you use PySDK version 0.9.0 and start AI server on systems equipped with ORCA1 AI hardware accelerator: Firmware image file '' is invalid or corrupt.

    This effectively prevents any usage of ORCA1 AI hardware accelerator with PySDK version 0.9.0, so you need to upgrade to version 0.9.1.
