Google Vision API文本检测Python示例使用项目:"google.com:cloudsdktool"不是我自己的项目 [英] Google Vision API text detection Python example uses project: "google.com:cloudsdktool" and not my own project
问题描述
我正在通过 github存储库研究Cloud Vision API的python示例.
我已经设置了项目并使用其密钥激活了服务帐户.我也叫gcloud auth
并输入了我的凭据.
I have already setup the project and activated the service account with its key. I have also called the gcloud auth
and entered my credentials.
这是我的代码(源自Vision API文本检测的python示例):
Here is my code (as derived from the python example of Vision API text detection):
import base64
import os
import re
import sys
from googleapiclient import discovery
from googleapiclient import errors
import nltk
from nltk.stem.snowball import EnglishStemmer
from oauth2client.client import GoogleCredentials
import redis
DISCOVERY_URL = 'https://{api}.googleapis.com/$discovery/rest?version={apiVersion}' # noqa
BATCH_SIZE = 10
class VisionApi:
"""Construct and use the Google Vision API service."""
def __init__(self, api_discovery_file='/home/saadq/Dev/Projects/TM-visual-search/credentials-key.json'):
self.credentials = GoogleCredentials.get_application_default()
print self.credentials.to_json()
self.service = discovery.build(
'vision', 'v1', credentials=self.credentials,
discoveryServiceUrl=DISCOVERY_URL)
print DISCOVERY_URL
def detect_text(self, input_filenames, num_retries=3, max_results=6):
"""Uses the Vision API to detect text in the given file.
"""
images = {}
for filename in input_filenames:
with open(filename, 'rb') as image_file:
images[filename] = image_file.read()
batch_request = []
for filename in images:
batch_request.append({
'image': {
'content': base64.b64encode(
images[filename]).decode('UTF-8')
},
'features': [{
'type': 'TEXT_DETECTION',
'maxResults': max_results,
}]
})
request = self.service.images().annotate(
body={'requests': batch_request})
try:
responses = request.execute(num_retries=num_retries)
if 'responses' not in responses:
return {}
text_response = {}
for filename, response in zip(images, responses['responses']):
if 'error' in response:
print("API Error for %s: %s" % (
filename,
response['error']['message']
if 'message' in response['error']
else ''))
continue
if 'textAnnotations' in response:
text_response[filename] = response['textAnnotations']
else:
text_response[filename] = []
return text_response
except errors.HttpError as e:
print("Http Error for %s: %s" % (filename, e))
except KeyError as e2:
print("Key error: %s" % e2)
vision = VisionApi()
print vision.detect_text(['test_article.png'])
这是我收到的错误消息:
This is the error message I am getting:
Http Error for test_article.png: <HttpError 403 when requesting https://vision.googleapis.com/v1/images:annotate?alt=json returned "Google Cloud Vision API has not been used in project google.com:cloudsdktool before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/vision.googleapis.com/overview?project=google.com:cloudsdktool then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.">
我希望能够使用我自己的项目作为示例,而不是默认项目(google.com:cloudsdktool).
I want to be able to use my own project for the example and not the default (google.com:cloudsdktool).
推荐答案
下载您创建的凭据并更新GOOGLE_APPLICATION_CREDENTIALS环境变量以指向该文件:
Download the credentials you created and update the GOOGLE_APPLICATION_CREDENTIALS environment variable to point to that file:
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/your/credentials-key.json
