我正在为Google Cloud Vision API执行“标签检测”教程。
当我将图像传递给命令时,我希望能找回一些json,告诉我图像中有什么。警告:oauth2client.util:build()至多需要2个位置参数(给出3个)
但是,我得到这个错误,而不是。

很多在这里。
但项目API 已启用。
所以这是错误信息的一部分是错误的。
看来,“最新版本的oauth2client v2.0.0发生了变化,它打破了与google-api-python-client模块的兼容性”。

我在应用此修正...
pip install --upgrade git+https://github.com/google/google-api-python-client
应用此修复后,我得到更少的错误...

看来,这个错误消息: “无可以找到处理程序的记录器“oauth2client.util” 实际上是掩盖更详细的警告/错误消息 ,我可以看到更详细d一个通过将此代码...

因此,没有我被困在此错误消息:
警告:oauth2client.util:建立()采用最多2位置参数(给出3)
有人建议,可以通过使用命名参数而不是位置表示法来避免此错误。

但是,我不确定究竟在哪里可以进行此更改。
我实际上没有在代码中看到oauth2client.util:build()函数。
下面是谷歌代码(略有修改):
>cat label_request.py
import argparse
import base64
import httplib2
from apiclient.discovery import build
from oauth2client.client import GoogleCredentials
import logging
logging.basicConfig()
def main(photo_file):
'''Run a label request on a single image'''
API_DISCOVERY_FILE = 'https://vision.googleapis.com/$discovery/rest?version=v1'
http = httplib2.Http()
credentials = GoogleCredentials.get_application_default().create_scoped(
['https://www.googleapis.com/auth/cloud-platform'])
credentials.authorize(http)
service = build('vision', 'v1', http, discoveryServiceUrl=API_DISCOVERY_FILE)
with open(photo_file, 'rb') as image:
image_content = base64.b64encode(image.read())
service_request = service.images().annotate(
body={
'requests': [{
'image': {
'content': image_content
},
'features': [{
'type': 'LABEL_DETECTION',
'maxResults': 1,
}]
}]
})
response = service_request.execute()
label = response['responses'][0]['labelAnnotations'][0]['description']
print('Found label: %s for %s' % (label, photo_file))
return 0
if __name__ == '__main__':
parser = argparse.ArgumentParser()
parser.add_argument(
'image_file', help='The image you\'d like to label.')
args = parser.parse_args()
main(args.image_file)
调用堆栈指示'build'方法可能会将参数传递给堆栈。你会修改第21行('service = build(...)'以使用命名参数。 – TehCorwiz
很好的建议。谢谢。构建方法似乎不喜欢命名参数。也许我会尝试恢复到版本google-client-api that works。 –
