如何使用Python在IBM Watson Visual Recognition中使用变量创建类(而不是分类器)？

from ibm_watson import VisualRecognitionV3
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator

authenticator = IAMAuthenticator('your_api_key')

visual_recognition = VisualRecognitionV3(
    version='2018-03-19',
    authenticator=authenticator
)

visual_recognition.set_service_url('https://gateway.watsonplatform.net/visual-recognition/api')

def create_custom_class(class_name, classifier_id):
    response = visual_recognition.create_class(
        classifier_id=classifier_id,
        class_name=class_name
    ).get_result()
    return response

response = create_custom_class('MyClass', 'your_classifier_id')
print(response)
