#put_trained_model_alias(arguments = {}) ⇒ Object

Creates a new model alias (or reassigns an existing one) to refer to the trained model

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :model_alias (String) —

    The trained model alias to update

  • :model_id (String) —

    The trained model where the model alias should be assigned

  • :reassign (Boolean) —

    If the model_alias already exists and points to a separate model_id, this parameter must be true. Defaults to false.

  • :headers (Hash) —

    Custom HTTP headers
