 """Create an Amazon SageMaker endpoint configuration. The endpoint configuration identifies the Amazon SageMaker model (created using the ``CreateModel`` API) and the hardware configuration on which to deploy the model. Provide this endpoint configuration to the ``CreateEndpoint`` API, which then launches the hardware and deploys the model. Args: name (str):
 Name of the Amazon SageMaker endpoint configuration to create. model_name (str):
 Name of the Amazon SageMaker ``Model``. initial_instance_count (int):
 Minimum number of EC2 instances to launch. The actual number of active instances for an endpoint at any given time varies due to autoscaling. instance_type (str):
 Type of EC2 instance to launch, for example, 'ml.c4.xlarge'. accelerator_type (str):
 Type of Elastic Inference accelerator to attach to the instance. For example, 'ml.eia1.medium'. For more information: https://docs.aws.amazon.com/sagemaker/latest/dg/ei.html tags(List[dict[str, str]]):
 Optional. The list of tags to add to the endpoint config. Example: For more information about tags, see https://boto3.amazonaws.com/v1/documentation\ /api/latest/reference/services/sagemaker.html#SageMaker.Client.add_tags Returns: str: Name of the endpoint point configuration created. """
