找不到记录器“grpc.\u plugin\u wrapping”的处理程序

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

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

我们正在使用python2.7和googlecloud,googlecloud语言。

预期没有错误,代码以前正在工作。不知道什么是导火索。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
