Объект модуля не имеет атрибута BigqueryV2 - Local Apache Beam

Я пытаюсь запустить конвейер локально (Sierra) с помощью Apache Beam, используя предоставленные лучом API-интерфейсы ввода-вывода для Google BigQuery.

Я настроил свою среду с помощью Virtualenv, как было предложено Быстрый старт по Beam Python, и я можно запустить пример wordcount.py. Я также могу правильно запустить настраиваемый конвейер с beam.Create и beam.ParDo.

Но я не могу запустить конвейер с BigQuery I / O. Есть идеи, что я делаю неправильно?

Скрипт python следующий.

import apache_beam as beam
from apache_beam.utils.pipeline_options import PipelineOptions
from apache_beam.io import WriteToText


class MyDoFn(beam.DoFn):
  def process(self, element):
    return element


def run():
  opts = {
    'project': 'gc-project-name'
  }
  p = beam.Pipeline(options=PipelineOptions(**opts))

  input_query = "SELECT name FROM `gc-project-name.dataset_name.table_name`"

  (p
   | beam.io.Read(beam.io.BigQuerySource(query=input_query))
   | beam.ParDo(MyDoFn())
   | beam.io.WriteToText('output.txt')
  )

  result = p.run()
  result.wait_until_finish()

if __name__ == '__main__':
  run()

Когда я запускаю его, я получаю следующую ошибку.
