        Args:
            image_uri (str or PipelineVariable): A Docker image URI.
            model_data (str or PipelineVariable): The S3 location of a SageMaker
                model data ``.tar.gz`` file (default: None).
            role (str): An AWS IAM role (either name or full ARN). The Amazon
                SageMaker training jobs and APIs that create Amazon SageMaker
                endpoints use this role to access training data and model
                artifacts. After the endpoint is created, the inference code
                might use the IAM role if it needs to access some AWS resources.
                It can be null if this is being used to create a Model to pass
                to a ``PipelineModel`` which has its own Role field. (default:
                None)
            predictor_cls (callable[string, sagemaker.session.Session]): A
                function to call to create a predictor (default: None). If not
                None, ``deploy`` will return the result of invoking this
                function on the created endpoint name.
            env (dict[str, str] or dict[str, PipelineVariable]): Environment variables
                to run with ``image_uri`` when hosted in SageMaker (default: None).
            name (str): The model name. If None, a default model name will be
                selected on each ``deploy``.
            vpc_config (dict[str, list[str]] or dict[str, list[PipelineVariable]]):
                The VpcConfig set on the model (default: None)
                * 'Subnets' (list[str]): List of subnet ids.
                * 'SecurityGroupIds' (list[str]): List of security group ids.
            sagemaker_session (sagemaker.session.Session): A SageMaker Session
                object, used for SageMaker interactions (default: None). If not
                specified, one is created using the default AWS configuration
                chain.
            enable_network_isolation (Boolean or PipelineVariable): Default False.
                if True, enables network isolation in the endpoint, isolating the model
                container. No inbound or outbound network calls can be made to
                or from the model container.
            model_kms_key (str): KMS key ARN used to encrypt the repacked
                model archive file if the model is repacked
            image_config (dict[str, str] or dict[str, PipelineVariable]): Specifies
                whether the image of model container is pulled from ECR, or private
                registry in your VPC. By default it is set to pull model container
                image from ECR. (default: None).
            source_dir (str): The absolute, relative, or S3 URI Path to a directory
                with any other training source code dependencies aside from the entry
                point file (default: None). If ``source_dir`` is an S3 URI, it must
                point to a tar.gz file. Structure within this directory is preserved
                when training on Amazon SageMaker. If 'git_config' is provided,
                'source_dir' should be a relative location to a directory in the Git repo.
                If the directory points to S3, no code is uploaded and the S3 location
                is used instead.

                .. admonition:: Example

                    With the following GitHub repo directory structure:

                    >>> |----- README.md
                    >>> |----- src
                    >>>         |----- inference.py
                    >>>         |----- test.py

                    You can assign entry_point='inference.py', source_dir='src'.
            code_location (str): Name of the S3 bucket where custom code is
                uploaded (default: None). If not specified, the default bucket
                created by ``sagemaker.session.Session`` is used.
            entry_point (str): The absolute or relative path to the local Python
                source file that should be executed as the entry point to
                model hosting. (Default: None). If ``source_dir`` is specified, then ``entry_point``
                must point to a file located at the root of ``source_dir``.
                If 'git_config' is provided, 'entry_point' should be
                a relative location to the Python source file in the Git repo.

                Example:
                    With the following GitHub repo directory structure:

                    >>> |----- README.md
                    >>> |----- src
                    >>>         |----- inference.py
                    >>>         |----- test.py

                    You can assign entry_point='src/inference.py'.
            container_log_level (int or PipelineVariable): Log level to use within the
                container (default: logging.INFO). Valid values are defined in the Python
                logging module.
            dependencies (list[str]): A list of absolute or relative paths to directories
                with any additional libraries that should be exported
                to the container (default: []). The library folders are
                copied to SageMaker in the same folder where the entrypoint is
                copied. If 'git_config' is provided, 'dependencies' should be a
                list of relative locations to directories with any additional
                libraries needed in the Git repo. If the ```source_dir``` points
                to S3, code will be uploaded and the S3 location will be used
                instead.

                .. admonition:: Example

                    The following call

                    >>> Model(entry_point='inference.py',
                    ...       dependencies=['my/libs/common', 'virtual-env'])

                    results in the following structure inside the container:

                    >>> $ ls

                    >>> opt/ml/code
                    >>>     |------ inference.py
                    >>>     |------ common
                    >>>     |------ virtual-env

                This is not supported with "local code" in Local Mode.
            git_config (dict[str, str]): Git configurations used for cloning
                files, including ``repo``, ``branch``, ``commit``,
                ``2FA_enabled``, ``username``, ``password`` and ``token``. The
                ``repo`` field is required. All other fields are optional.
                ``repo`` specifies the Git repository where your training script
                is stored. If you don't provide ``branch``, the default value
                'master' is used. If you don't provide ``commit``, the latest
                commit in the specified branch is used.

                .. admonition:: Example

                    The following config:

                    >>> git_config = {'repo': 'https://github.com/aws/sagemaker-python-sdk.git',
                    >>>               'branch': 'test-branch-git-config',
                    >>>               'commit': '329bfcf884482002c05ff7f44f62599ebc9f445a'}

                    results in cloning the repo specified in 'repo', then
                    checking out the 'master' branch, and checking out the specified
                    commit.

                ``2FA_enabled``, ``username``, ``password`` and ``token`` are
                used for authentication. For GitHub (or other Git) accounts, set
                ``2FA_enabled`` to 'True' if two-factor authentication is
                enabled for the account, otherwise set it to 'False'. If you do
                not provide a value for ``2FA_enabled``, a default value of
                'False' is used. CodeCommit does not support two-factor
                authentication, so do not provide "2FA_enabled" with CodeCommit
                repositories.

                For GitHub and other Git repos, when SSH URLs are provided, it
                doesn't matter whether 2FA is enabled or disabled. You should
                either have no passphrase for the SSH key pairs or have the
                ssh-agent configured so that you will not be prompted for the SSH
                passphrase when you run the 'git clone' command with SSH URLs. When
                HTTPS URLs are provided, if 2FA is disabled, then either ``token``
                or ``username`` and ``password`` are be used for authentication if provided.
                ``Token`` is prioritized. If 2FA is enabled, only ``token`` is used
                for authentication if provided. If required authentication info
                is not provided, the SageMaker Python SDK attempts to use local credentials
                to authenticate. If that fails, an error message is thrown.

                For CodeCommit repos, 2FA is not supported, so ``2FA_enabled``
                should not be provided. There is no token in CodeCommit, so
                ``token`` should also not be provided. When ``repo`` is an SSH URL,
                the requirements are the same as GitHub  repos. When ``repo``
                is an HTTPS URL, ``username`` and ``password`` are used for
                authentication if they are provided. If they are not provided,
                the SageMaker Python SDK attempts to use either the CodeCommit
                credential helper or local credential storage for authentication.

                file which should be executed as the entry point to model
                hosting. If ``source_dir`` is specified, then ``entry_point``

                If the directory points to S3, no code will be uploaded and the S3 location
                will be used instead.

            predictor_cls (callable[string, sagemaker.session.Session]): A
                function to call to create a predictor (default: None). If not
                None, ``deploy`` will return the result of invoking this
                function on the created endpoint name.
            env (dict[str, str] or dict[str, PipelineVariable]): Environment variables to
                run with ``image_uri`` when hosted in SageMaker (default: None).
            name (str): The model name. If None, a default model name will be
                selected on each ``deploy``.
            container_log_level (int or PipelineVariable): Log level to use within
                the container (default: logging.INFO). Valid values are defined
                in the Python logging module.
            code_location (str): Name of the S3 bucket where custom code is
                uploaded (default: None). If not specified, default bucket
                created by ``sagemaker.session.Session`` is used.
            sagemaker_session (sagemaker.session.Session): A SageMaker Session
                object, used for SageMaker interactions (default: None). If not
                specified, one is created using the default AWS configuration
                chain.
            dependencies (list[str]): A list of paths to directories (absolute
                or relative) with any additional libraries that will be exported
                to the container (default: []). The library folders will be
                copied to SageMaker in the same folder where the entrypoint is
                copied. If 'git_config' is provided, 'dependencies' should be a
                list of relative locations to directories with any additional
                libraries needed in the Git repo. If the ```source_dir``` points
                to S3, code will be uploaded and the S3 location will be used

                .. admonition:: Example

                    The following call

                    ...       dependencies=['my/libs/common', 'virtual-env'])

                    results in the following inside the container:

                    >>>     |------ virtual-env

                This is not supported with "local code" in Local Mode.
            git_config (dict[str, str]): Git configurations used for cloning
                files, including ``repo``, ``branch``, ``commit``,
                ``2FA_enabled``, ``username``, ``password`` and ``token``. The
                ``repo`` field is required. All other fields are optional.
                ``repo`` specifies the Git repository where your training script
                is stored. If you don't provide ``branch``, the default value
                'master' is used. If you don't provide ``commit``, the latest
                commit in the specified branch is used.

                .. admonition:: Example

                    The following config:

                    >>> git_config = {'repo': 'https://github.com/aws/sagemaker-python-sdk.git',
                    >>>               'branch': 'test-branch-git-config',
                    >>>               'commit': '329bfcf884482002c05ff7f44f62599ebc9f445a'}

                    results in cloning the repo specified in 'repo', then
                    checkout the 'master' branch, and checkout the specified
                    commit.

                ``2FA_enabled``, ``username``, ``password`` and ``token`` are
                used for authentication. For GitHub (or other Git) accounts, set
                ``2FA_enabled`` to 'True' if two-factor authentication is
                enabled for the account, otherwise set it to 'False'. If you do
                not provide a value for ``2FA_enabled``, a default value of
                'False' is used. CodeCommit does not support two-factor
                authentication, so do not provide "2FA_enabled" with CodeCommit
                repositories.

                For GitHub and other Git repos, when SSH URLs are provided, it
                doesn't matter whether 2FA is enabled or disabled; you should
                either have no passphrase for the SSH key pairs, or have the
                ssh-agent configured so that you will not be prompted for SSH
                passphrase when you do 'git clone' command with SSH URLs. When
                HTTPS URLs are provided: if 2FA is disabled, then either token
                or username+password will be used for authentication if provided
                (token prioritized); if 2FA is enabled, only token will be used
                for authentication if provided. If required authentication info
                is not provided, python SDK will try to use local credentials
                storage to authenticate. If that fails either, an error message
                will be thrown.

                For CodeCommit repos, 2FA is not supported, so '2FA_enabled'
                should not be provided. There is no token in CodeCommit, so
                'token' should not be provided too. When 'repo' is an SSH URL,
                the requirements are the same as GitHub-like repos. When 'repo'
                is an HTTPS URL, username+password will be used for
                authentication if they are provided; otherwise, python SDK will
                try to use either CodeCommit credential helper or local
                credential storage for authentication.
