               variables. (Default: None).

              retrieve the default environment variables. (Default: None).
          model_version (str): Optional. The version of the model for which to retrieve the
              default environment variables. (Default: None).
          tolerate_vulnerable_model (bool): True if vulnerable versions of model
              specifications should be tolerated (exception not 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 models should be tolerated
              (exception not raised). False if these models should raise an exception.
              (Default: False).
          include_aws_sdk_env_vars (bool): True if environment variables for low-level AWS API call
              should be included. The `Model` class of the SageMaker Python SDK inserts environment
              variables that would be required when making the low-level AWS API call.
              (Default: True).
          sagemaker_session (sagemaker.session.Session): A SageMaker Session
              object, used for SageMaker interactions. If not
              specified, one is created using the default AWS configuration
              chain. (Default: sagemaker.jumpstart.constants.DEFAULT_JUMPSTART_SAGEMAKER_SESSION).
          instance_type (str): An instance type to optionally supply in order to get environment
              variables specific for the instance type.
          script (JumpStartScriptScope): The JumpStart script for which to retrieve environment
              variables.
      Returns:
          dict: The variables to use for the model.
  
      Raises:
