使用 IBM Watson Visual Recognition 创建分类器时出现 503 Internal Server Error

Question

我是 Watson Visual Recognition 的初学者，正在尝试创建一个自定义分类器来对狗的图像进行分类。但是，当我尝试创建如下代码片段所示的分类器时，出现错误。

with open ('beagle.zip','rb') as beagles,open ('golden-retriever.zip','rb') as golden_retrievers,open `('husky.zip','rb') as huskies:`
       classifier = visrec.create_classifier(name = 'dog_classifier',positive_examples =     `{'beagles':beagles,'golden_retrievers':golden_retrievers,'huskies': 'huskies'})`

这里是错误：

    classifier = visrec.create_classifier(name = 'dog_classifier',positive_examples = {'beagles':beagles,'golden_retrievers':golden_retrievers,'huskies': 'huskies'})
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/ibm_watson/visual_recognition_v3.py", line 282, in create_classifier
    response = self.send(request)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/ibm_cloud_sdk_core/base_service.py", line 302, in send
    raise ApiException(response.status_code, http_response=response)

, Code: 503

我该如何解决这个问题？

Answer 1

503表示服务不可用。如果你试图击中它时可能会下降。

当前状态显示已启动 - https://cloud.ibm.com/status

您是否仍然遇到同样的错误？

API 文档 (https://cloud.ibm.com/apidocs/visual-recognition/visual-recognition-v3?code=python#createclassifier) 中的示例代码是

import json
from ibm_watson import VisualRecognitionV3
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator

authenticator = IAMAuthenticator('{apikey}')
visual_recognition = VisualRecognitionV3(
    version='2018-03-19',
    authenticator=authenticator
)

visual_recognition.set_service_url('{url}')

with open('./beagle.zip', 'rb') as beagle, open(
        './golden-retriever.zip', 'rb') as goldenretriever, open(
            './husky.zip', 'rb') as husky, open(
                './cats.zip', 'rb') as cats:
    model = visual_recognition.create_classifier(
        'dogs',
        positive_examples={'beagle': beagle, 'goldenretriever': goldenretriever, 'husky': husky},
        negative_examples=cats).get_result()
print(json.dumps(model, indent=2))

确保您已正确设置服务 url。端点应与您在其中创建视觉识别服务的区域相匹配。您可以验证 url 应该是什么，因为它将在您从中获取 API 密钥的同一位置可用。

在我写上一段时考虑到这一点，我意识到由于您是 Watson Visual Recognition 的新手，您可能尚未创建服务实例或生成 API 密钥。由于该服务已被弃用，您可能无法这样做。如果是这种情况，恐怕您将无法使用该服务。
