  """Launch a BigQuery confusion matrix job and waits for it to finish.

  Args:
      project: Project to run BigQuery confusion matrix job.
      location: Location to run the BigQuery confusion matrix
        job. If not set, default to `US` multi-region. For more details, see
        https://cloud.google.com/bigquery/docs/locations#specifying_your_location
      model: BigQuery ML model for confusion
        matrix. For more details, see
        https://cloud.google.com/bigquery-ml/docs/reference/standard-sql/bigqueryml-syntax-confusion#eval_model_name
      table_name: BigQuery table id of the input table that
        contains the evaluation data. For more details, see
        https://cloud.google.com/bigquery-ml/docs/reference/standard-sql/bigqueryml-syntax-confusion#eval_table_name
      query_statement: Query statement string used to generate
        the evaluation data. For more details, see
        https://cloud.google.com/bigquery-ml/docs/reference/standard-sql/bigqueryml-syntax-confusion#eval_query_statement
      threshold: A custom threshold for your binary
        classification model used for evaluation. For more details, see
        https://cloud.google.com/bigquery-ml/docs/reference/standard-sql/bigqueryml-syntax-confusion#eval_threshold
      query_parameters: Query parameters for
        standard SQL queries. If query_parameters are both specified in here
        and in job_configuration_query, the value in here will override the
        other one.
      job_configuration_query: A json formatted string
        describing the rest of the job configuration. For more details, see
        https://cloud.google.com/bigquery/docs/reference/rest/v2/Job#JobConfigurationQuery
      labels: The labels associated with this job. You can
        use these to organize and group your jobs. Label keys and values can
        be no longer than 63 characters, can only containlowercase letters,
        numeric characters, underscores and dashes. International characters
        are allowed. Label values are optional. Label keys must start with a
        letter and each label in the list must have a different key.
          Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

  Returns:
      confusion_matrix: Describes common metrics applicable to the type of model supplied.
        For more details, see
        https://cloud.google.com/bigquery-ml/docs/reference/standard-sql/bigqueryml-syntax-confusion#mlconfusion_matrix_output
      gcp_resources: Serialized gcp_resources proto tracking the BigQuery job.
          For more details, see
          https://github.com/kubeflow/pipelines/blob/master/components/google-cloud/google_cloud_pipeline_components/proto/README.md.
