Prerequisites

OSS is activated, and Machine Learning Studio is authorized to access OSS. For more information, see Activate OSS and Grant the permissions that are required to use Machine Learning Designer.

Limits

• The model quantize component is available only in Machine Learning Designer of Machine Learning Platform for AI.

• You can use the model quantize component based only on the computing resources of Deep Learning Containers (DLC) of Machine Learning Platform for AI.

• If an object detection component is configured as an upstream component of the model quantize component, make sure that the model-related configurations and the dataset configurations for the two components are the same.
