Google cloud vision api::AttributeError:“WebDetection”对象没有“best\u guess\u labels”属性

我试图使用python从googlecloudvisionapi调用函数“detectweb”。它的最好的一个标签叫“我猜不出你”。当我试图调用这个方法时,它抛出了一个错误 “AttributeError:'WebDetection'对象没有“best\u guess\u labels”属性:

https://cloud.google.com/docs/authentication/getting-started

import os
os.environ["GOOGLE_APPLICATION_CREDENTIALS"]="WebDetection.json"

“detect web”的功能取自此链接--> https://cloud.google.com/vision/docs/detecting-web

下面是从上面链接复制的函数,供您随时参考。

def detect_web(path):
    """Detects web annotations given an image."""
    client = vision.ImageAnnotatorClient()

with io.open(path, 'rb') as image_file:
    content = image_file.read()

image = vision.types.Image(content=content)

response = client.web_detection(image=image)
annotations = response.web_detection

if annotations.best_guess_labels:
    for label in annotations.best_guess_labels:
        print('\nBest guess label: {}'.format(label.label))

if annotations.pages_with_matching_images:
    print('\n{} Pages with matching images found:'.format(
        len(annotations.pages_with_matching_images)))

    for page in annotations.pages_with_matching_images:
        print('\n\tPage url   : {}'.format(page.url))

        if page.full_matching_images:
            print('\t{} Full Matches found: '.format(
                   len(page.full_matching_images)))

            for image in page.full_matching_images:
                print('\t\tImage url  : {}'.format(image.url))

        if page.partial_matching_images:
            print('\t{} Partial Matches found: '.format(
                   len(page.partial_matching_images)))

            for image in page.partial_matching_images:
                print('\t\tImage url  : {}'.format(image.url))

if annotations.web_entities:
    print('\n{} Web entities found: '.format(
        len(annotations.web_entities)))

    for entity in annotations.web_entities:
        print('\n\tScore      : {}'.format(entity.score))
        print(u'\tDescription: {}'.format(entity.description))

if annotations.visually_similar_images:
    print('\n{} visually similar images found:\n'.format(
        len(annotations.visually_similar_images)))

    for image in annotations.visually_similar_images:
        print('\tImage url    : {}'.format(image.url))

detect_web("download.jpg")

我得到以下错误:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-71-6d38dd9b3a76> in <module>()
----> 1 detect_web("download.jpg")

<ipython-input-70-c127dc709a32> in detect_web(path)
     13     annotations = response.web_detection
     14 
---> 15     if annotations.best_guess_labels:
     16         for label in annotations.best_guess_labels:
     17             print('\nBest guess label: {}'.format(label.label))

AttributeError: 'WebDetection' object has no attribute 'best_guess_labels'

我试着调试,发现“best\u guess\u labels”不是Json文件的一部分。我不确定json文件是否损坏了,但是我试图重做这个练习,但是仍然得到相同的错误。

是什么导致了这个问题?

我一直在用 google-cloud-vision==0.34.0 用下面的代码,我没有任何错误,以及我得到一个 Best guess label: document

import argparse
import io
import re
from google.cloud import vision
import os
os.environ["GOOGLE_APPLICATION_CREDENTIALS"]="file.json"

def detect_web(path):
    """Detects web annotations given an image."""
    client = vision.ImageAnnotatorClient()

    with io.open(path, 'rb') as image_file:
        content = image_file.read()

    image = vision.types.Image(content=content)

    response = client.web_detection(image=image)
    annotations = response.web_detection

    if annotations.best_guess_labels:
        for label in annotations.best_guess_labels:
            print('\nBest guess label: {}'.format(label.label))

    if annotations.pages_with_matching_images:
        print('\n{} Pages with matching images found:'.format(
            len(annotations.pages_with_matching_images)))

    for page in annotations.pages_with_matching_images:
        print('\n\tPage url   : {}'.format(page.url))

        if page.full_matching_images:
            print('\t{} Full Matches found: '.format(
                   len(page.full_matching_images)))

            for image in page.full_matching_images:
                print('\t\tImage url  : {}'.format(image.url))

        if page.partial_matching_images:
            print('\t{} Partial Matches found: '.format(
                   len(page.partial_matching_images)))

            for image in page.partial_matching_images:
                print('\t\tImage url  : {}'.format(image.url))
if __name__ == '__main__':
    detect_web("file.jpg")
