Google cloud dataflow ImportError:没有名为options.value\u的模块提供程序

以下管道与DirectRunner一起工作，但与DataflowRunner一起引发以下异常。 如何调试此类错误？这对我来说似乎是相当不透明的

p = beam.Pipeline("DataflowRunner", argv=[
    '--project', project,
    '--staging_location', staging_location,
    '--temp_location', temp_location,
    '--output', output_gcs
])  
(p  
 | 'read events' >> beam.io.Read(beam.io.BigQuerySource(query=query, use_standard_sql=True))
 | 'write' >> beam.io.WriteToText(output_gcs)
)   
p.run().wait_until_finish()

提高

ImportError: No module named options.value_provider

value_provider是最近引入的一个模块，用于处理python SDK中的模板。但是，我在您的代码片段中没有看到任何模板，因此可能是包不匹配。您是否为SDK和worker使用匹配的版本？您可以查看worker启动日志以检查已安装的软件包的版本。

这里也有相同的问题。正如Maria所指出的，apache_beam和google云数据流包之间存在不匹配问题

为了明确起见，以下命令将解决此问题：

pip2 install --upgrade apache_beam google-cloud-dataflow

您使用的sdk版本是什么？您是对的。问题是SDK不匹配。在本地，我安装了apache_beam和google云数据流“pip”。卸载apache_beam解决了此问题。
