502 Bad Gateway - Aufruf Scoring api Endpunkt

ich den folgenden Code aus der Community Notebook mit Predict Outdoor-Ausrüstung Kauf mit IBM Watson Machine Learning:502 Bad Gateway - Aufruf Scoring api Endpunkt

... 
<code omitted for brevity> 
... 

import urllib3, requests, json 
 
headers = urllib3.util.make_headers(basic_auth='{}:{}'.format(username, password)) 
url = '{}/v2/identity/token'.format(service_path) 
response = requests.get(url, headers=headers) 
mltoken = json.loads(response.text).get('token') 

endpoint_online = service_path + "/v2/online/deployments/" 
header_online = {'Content-Type': 'application/json', 'Authorization': mltoken} 
payload_online = {"artifactVersionHref": saved_model.meta.prop("modelVersionHref"), "name": "Product Line Prediction"} 
 
response_online = requests.post(endpoint_online, json=payload_online, headers=header_online) 
 
print response_online 
print response_online.text 

scoring_href = json.loads(response_online.text).get('entity').get('scoringHref') 
print scoring_href

Die Antwort

<Response [201]> 
{"metadata":{"guid":"4148","href":"https://ibm-watson-ml.mybluemix.net/v2/online/deployments/4148","createdAt":"2017-06-13T07:54:16.062Z","modifiedAt":"2017-06-13T07:54:16.062Z"},"entity":{"scoringHref":"https://ibm-watson-ml.mybluemix.net/32768/v2/scoring/4148"}}

Nächster Versuch, ein Tor zu erzielen:

payload_scoring = {"record":["M", 23, "Single", "Student"]} 
response_scoring = requests.put(scoring_href, json=payload_scoring, headers=header_online) 
 
print response_scoring.text
