object of type 'repeatedcompositecontainer' is not json serializable

The error you encountered is

TypeError: Object of type 'RepeatedCompositeContainer'
is not JSON serializable

The Vision library returns plain protobuf objects, which can be serialized to JSON using:

from google.protobuf.json_format
import MessageToJson
serialized = MessageToJson(original)

I have an api to call this function.,I have a function to detect labels from an anycodings_python image.,How can I have a function pointer template as a template parameter?,How to retrieve the value of the selected option from a dynamically created select in a table

GoogleVision.py

import os

from google.cloud
import vision
from google.cloud.vision
import types
from google.protobuf.json_format
import MessageToJson

class GoogleVision():

   def detectLabels(self, uri):

   client = vision.ImageAnnotatorClient()
image = types.Image()
image.source.image_uri = uri

response = client.label_detection(image = image)
labels = response.label_annotations

return labels

I have an api to call this function.

from flask_restful
import Resource
from flask
import request
from flask
import json
from util.GoogleVision
import GoogleVision

import os

class Vision(Resource):

   def get(self):

   return {
      "message": "API Working"
   }

def post(self):

   googleVision = GoogleVision()

req = request.get_json()

url = req['url']

result = googleVision.detectLabels(url)

return result

The Python "TypeError: Object of type function is not JSON serializable" occurs when we try to serialize a function to JSON. To solve the error, make sure to call the function and serialize the object that the function returns.,We called the function, so we serialized the dict object rather than trying to serialize the function itself.,To solve the error, make sure to call the function and serialize its return value rather than the function itself.,You have to add parenthesis to call a function, e.g. get_employee(), otherwise we pass a reference to the get_employee function to the json.dumps method which is not what we want.

Copied!
   import json

def get_employee():
   return {
      'name': 'Alice',
      'age': 30
   }

#⛔️ TypeError: Object of type
function is not JSON serializable
json_str = json.dumps(get_employee) #👈️ forgot to call
function

Copied!import json


def get_employee():
    return {'name': 'Alice', 'age': 30}


# ✅ call function get_employee() and NOT get_employee
json_str = json.dumps(get_employee())

print(json_str)  # 👉️ '{"name": "Alice", "age": 30}'
print(type(json_str))  # 👉️ <class 'str'>

使用 Google 客户端库与视觉库交互。

我有一个从图像中检测标签的功能。

GoogleVision.py

import os

from google.cloud
import vision
from google.cloud.vision
import types
from google.protobuf.json_format
import MessageToJson

class GoogleVision():

   def detectLabels(self, uri):

   client = vision.ImageAnnotatorClient()
image = types.Image()
image.source.image_uri = uri

response = client.label_detection(image = image)
labels = response.label_annotations

return labels

url = req['url']

result = googleVision.detectLabels(url)

return result

Vision 库返回普通的 protobuf 对象，可以使用以下命令将其序列化为 JSON:

from google.protobuf.json_format
import MessageToJson
serialized = MessageToJson(original)
