  """Launch a self-executing Beam Python file on Google Cloud using the
  Dataflow Runner.

  Args:
      location: Location of the Dataflow job. If not set, defaults to `'us-central1'`.
      python_module_path: The GCS path to the Python file to run.
      temp_location: A GCS path for Dataflow to stage temporary job files created during the execution of the pipeline.
      requirements_file_path: The GCS path to the pip requirements file.
      args: The list of args to pass to the Python file. Can include additional parameters for the Dataflow Runner.
      project: Project to create the Dataflow job. Defaults to the project in which the PipelineJob is run.

  Returns:
      gcp_resources: Serialized gcp_resources proto tracking the Dataflow job. For more details, see https://github.com/kubeflow/pipelines/blob/master/components/google-cloud/google_cloud_pipeline_components/proto/README.md.
