            entrypoint (list[str] or list[PipelineVariable]): The entrypoint for the
                processing job (default: None). This is in the form of a list of strings
                that make a command.
            volume_size_in_gb (int or PipelineVariable): Size in GB of the EBS volume
                to use for storing data during processing (default: 30).

                After this amount of time, Amazon SageMaker terminates the job,
                regardless of its current status. If `max_runtime_in_seconds` is not
                specified, the default value is 24 hours.
            base_job_name (str): Prefix for processing job name. If not specified,
                the processor generates a default job name, based on the
                processing image name and current timestamp.

                The behavior of setting these keys is as follows:
                * If `ExperimentName` is supplied but `TrialName` is not a Trial will be
                automatically created and the job's Trial Component associated with the Trial.
                * If `TrialName` is supplied and the Trial already exists the job's Trial Component
                will be associated with the Trial.
                * If both `ExperimentName` and `TrialName` are not supplied the trial component
                will be unassociated.
                * `TrialComponentDisplayName` is used for display in Studio.
                * Both `ExperimentName` and `TrialName` will be ignored if the Processor instance
                is built with :class:`~sagemaker.workflow.pipeline_context.PipelineSession`.
                However, the value of `TrialComponentDisplayName` is honored for display in Studio.

        The ``ScriptProcessor`` handles Amazon SageMaker Processing tasks for jobs
        using a machine learning framework, which allows for providing a script to be
        run as part of the Processing Job.

        Args:
            role (str): An AWS IAM role name or ARN. Amazon SageMaker Processing
                uses this role to access AWS resources, such as
                data stored in Amazon S3.
            image_uri (str or PipelineVariable): The URI of the Docker image to use for the
                processing jobs.
            command ([str]): The command to run, along with any command-line flags.
                Example: ["python3", "-v"].
            instance_count (int or PipelineVariable): The number of instances to run
                a processing job with.
            instance_type (str or PipelineVariable): The type of EC2 instance to use for
                processing, for example, 'ml.c4.xlarge'.
            volume_size_in_gb (int or PipelineVariable): Size in GB of the EBS volume
                to use for storing data during processing (default: 30).
            volume_kms_key (str or PipelineVariable): A KMS key for the processing
                volume (default: None).
            output_kms_key (str or PipelineVariable): The KMS key ID for processing
                job outputs (default: None).
            max_runtime_in_seconds (int or PipelineVariable): Timeout in seconds (default: None).
                After this amount of time, Amazon SageMaker terminates the job,
                regardless of its current status. If `max_runtime_in_seconds` is not
                specified, the default value is 24 hours.
            base_job_name (str): Prefix for processing name. If not specified,
                the processor generates a default job name, based on the
                processing image name and current timestamp.
            sagemaker_session (:class:`~sagemaker.session.Session`):
                Session object which manages interactions with Amazon SageMaker and
                any other AWS services needed. If not specified, the processor creates
                one using the default AWS configuration chain.
            env (dict[str, str] or dict[str, PipelineVariable])): Environment variables to

            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.
            inputs (list[:class:`~sagemaker.processing.ProcessingInput`]): Input files for
                the processing job. These must be provided as
                :class:`~sagemaker.processing.ProcessingInput` objects (default: None).
            outputs (list[:class:`~sagemaker.processing.ProcessingOutput`]): Outputs for
                the processing job. These can be specified as either path strings or
                :class:`~sagemaker.processing.ProcessingOutput` objects (default: None).
            arguments (list[str] or list[PipelineVariable]): A list of string arguments
                to be passed to a processing job (default: None).
            wait (bool): Whether the call should wait until the job completes (default: True).
            logs (bool): Whether to show the logs produced by the job.
                Only meaningful when wait is True (default: True).
            job_name (str): Processing job name. If not specified, the processor generates
                a default job name, based on the base job name and current timestamp.
            experiment_config (dict[str, str]): Experiment management configuration.
                Optionally, the dict can contain three keys:
                'ExperimentName', 'TrialName', and 'TrialComponentDisplayName'.
                The behavior of setting these keys is as follows:
                * If `ExperimentName` is supplied but `TrialName` is not a Trial will be
                automatically created and the job's Trial Component associated with the Trial.
                * If `TrialName` is supplied and the Trial already exists the job's Trial Component
                will be associated with the Trial.
                * If both `ExperimentName` and `TrialName` are not supplied the trial component
                will be unassociated.
                * `TrialComponentDisplayName` is used for display in Studio.
                * Both `ExperimentName` and `TrialName` will be ignored if the Processor instance
                is built with :class:`~sagemaker.workflow.pipeline_context.PipelineSession`.
                However, the value of `TrialComponentDisplayName` is honored for display in Studio.
            kms_key (str): The ARN of the KMS key that is used to encrypt the
                user code file (default: None).
        Returns:
            None or pipeline step arguments in case the Processor instance is built with
            :class:`~sagemaker.workflow.pipeline_context.PipelineSession`
