我正在尝试运行我的多标签文本分类预测模型，但出现以下错误消息：

TypeError                                 Traceback (most recent call last)
<ipython-input-6-8eeb93c56258> in <module>

我对谷歌给你的默认代码做了一些小改动：

   ...: from google.api_core.client_options import ClientOptions
   ...: from google.cloud import automl_v1
   ...: # from google.cloud.automl_v1.proto import service_pb2
   ...: 
   ...: def inline_text_payload(content):
   ...:   return {'text_snippet': {'content': content, 'mime_type': 'text/plain'} }
   ...: 
   ...: def pdf_payload(file_path):
   ...:   return {'document': {'input_config': {'gcs_source': {'input_uris': [file_path] } } } }
   ...: 
   ...: def get_prediction(content, model_name):
   ...:   options = ClientOptions(api_endpoint='automl.googleapis.com')
   ...:   prediction_client = automl_v1.PredictionServiceClient(client_options=options)
   ...: 
   ...:   payload = inline_text_payload(content)
   ...:   # Uncomment the following line (and comment the above line) if want to predict on PDFs.
   ...:   # payload = pdf_payload(file_path)
   ...: 
   ...:   params = {}
   ...:   request = prediction_client.predict(model_name, payload, params)
   ...:   return request  # waits until request is returned
   ...: 
   ...: def predecir(content, model_name):
   ...: 
   ...:   print(get_prediction(content, model_name))

我尝试安装以前版本的 google-cloud-automl 但没有解决方案。

我正在使用的当前版本是：

google-api-core==1.26.0
google-cloud-automl==2.1.0

【解决方案1】：

错误是无法识别位置参数。只需添加每个参数的名称。您可以查看predict reference中的参数。

request = prediction_client.predict(name=model_name, payload=payload, params=params)
