尝试将python的Google视觉响应转换为字典时出现属性错误DESCRIPTOR [英] Attribute error DESCRIPTOR while trying to convert google vision response to dictionary with python

问题描述

我在Windows上，使用 Python 3.8.6rc1 ， protobuf版本3.13.0 和 google-cloud-vision版本2.0.0

I am on Windows, using Python 3.8.6rc1, protobuf version 3.13.0 and google-cloud-vision version 2.0.0.

我的代码是:

from google.protobuf.json_format import MessageToDict
from google.cloud import vision
    
client = vision.ImageAnnotatorClient()
response = client.annotate_image({
            'image': {'source': {'image_uri': 'https://images.unsplash.com/photo-1508138221679-760a23a2285b?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=800&q=60'}},
        })
MessageToDict(response)

它在 MessageToDict(response)处失败，我有一个属性错误:"DESCRIPTOR" .似乎 response 不是有效的protobuf对象.有人能帮我吗?谢谢

It fails at MessageToDict(response), I have an attribute error: "DESCRIPTOR". It seems like the response is not a valid protobuf object. Can someone help me? Thank you

推荐答案

这并不能真正回答我的问题，但是我发现解决该问题并访问protobuf对象的一种方法是使用 response._pb ，因此代码变为:

This does not really answer my question but I find that one way to solve it and access the protobuf object is to use response._pb so the code becomes:

response = client.annotate_image({
            'image': {'source': {'image_uri': 'https://images.unsplash.com/photo-1508138221679-760a23a2285b?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=800&q=60'}},
        })
MessageToDict(response._pb)
