Вот как должен выглядеть код:
import requests, json
subs_key = API_KEY
uri_base = 'https://api.cognitive.microsoft.com/inkrecognizer/v1.0-preview/recognize'
headers = {'Content-type': 'application/json',
"Ocp-Apim-Subscription-Key": subs_key}
body = {}
response =requests.request('PUT', uri_base, json=body, data=None, headers=headers)
print('Response:')
parsed =json.loads(response.text)
print(json.dumps(parsed, sort_keys=True, indent=2))
А вам нужно будет добавить в тело 'language'
и 'strokes'
