    Ideally this function should not be called directly, rather it should be called from the
    fit() function inside framework estimator.

    Args:
        framework (str): The name of the framework or algorithm.
        region (str): The AWS region.
        version (str): The framework or algorithm version. This is required if there is
            more than one supported version for the given framework or algorithm.
        py_version (str): The Python version. This is required if there is
            more than one supported Python version for the given framework version.
        instance_type (str): The SageMaker instance type. For supported types, see
            https://aws.amazon.com/sagemaker/pricing. This is required if
            there are different images for different processor types.
        accelerator_type (str): Elastic Inference accelerator type. For more, see
            https://docs.aws.amazon.com/sagemaker/latest/dg/ei.html.
        image_scope (str): The image type, i.e. what it is used for.
            Valid values: "training", "inference", "inference_graviton", "eia".
            If ``accelerator_type`` is set, ``image_scope`` is ignored.
        container_version (str): the version of docker image.
            Ideally the value of parameter should be created inside the framework.
            For custom use, see the list of supported container versions:
            https://github.com/aws/deep-learning-containers/blob/master/available_images.md
            (default: None).
        distribution (dict): A dictionary with information on how to run distributed training
        training_compiler_config (:class:`~sagemaker.training_compiler.TrainingCompilerConfig`):
            A configuration class for the SageMaker Training Compiler
            (default: None).
        model_id (str): The JumpStart model ID for which to retrieve the image URI
            (default: None).
        model_version (str): The version of the JumpStart model for which to retrieve the
            image URI (default: None).
        tolerate_vulnerable_model (bool): ``True`` if vulnerable versions of model specifications
            should be tolerated without an exception raised. If ``False``, raises an exception if
            the script used by this version of the model has dependencies with known security
            vulnerabilities. (Default: False).
        tolerate_deprecated_model (bool): True if deprecated versions of model specifications
            should be tolerated without an exception raised. If False, raises an exception
            if the version of the model is deprecated. (Default: False).
        sdk_version (str): the version of python-sdk that will be used in the image retrieval.
            (default: None).
        inference_tool (str): the tool that will be used to aid in the inference.
            Valid values: "neuron, neuronx, None"
            (default: None).
        serverless_inference_config (sagemaker.serverless.ServerlessInferenceConfig):
            Specifies configuration related to serverless endpoint. Instance type is
            not provided in serverless inference. So this is used to determine processor type.

    Returns:
        str: The ECR URI for the corresponding SageMaker Docker image.

    Raises:
        NotImplementedError: If the scope is not supported.
        ValueError: If the combination of arguments specified is not supported or
            any PipelineVariable object is passed in.
        VulnerableJumpStartModelError: If any of the dependencies required by the script have
            known security vulnerabilities.
