python - 找不到记录器“grpc._plugin_wrapping”的处理程序

Question

我收到以下错误：

No handlers could be found for logger "grpc._plugin_wrapping"（完整的错误文本）

类似于https://github.com/googlecodelabs/iot-data-pipeline/issues/6

我们正在使用 python2.7 和 google-cloud、google-cloud-language。

预计没有错误，代码以前可以工作。不知道什么是触发器。错误发生在client.analyze_entities()

from google.cloud import language
creds = {
  ...
} 
client = language.LanguageServiceClient(credentials=creds)

 class EntityExtractionModule(BaseModule):
     """
     Extract entities from text
     """
     def __init__(self, data):
         BaseModule.__init__(self, data)

     def run(self):

        document = language.types.Document(content=full_text, language='en', type='PLAIN_TEXT',)
        r = client.analyze_entities(
          document=document,
          encoding_type='UTF32',
        )
        requests_log["entities"] = r
