VisualRecognitionV3新分类器状态=失败

Question

我在Bluemix中使用了以下Python SDK示例代码和输入图像文件来创建新的分类器。代码如下：

visual_recognition = VisualRecognitionV3('2016-05-20',api_key=apikey)with 
open('./cars.zip', 'rb') as cars, open('./trucks.zip', 'rb') as trucks:
            print(json.dumps(visual_recognition.create_classifier('Cars', 
            positive_examples=cars, negative_example=trucks), indent=2)) 
            print(json.dumps(visual_recognition.list_classifiers(), indent=2))

运行日志显示status=failed。

我遗漏了什么？

1. 这对我很管用：

从watson_developer_cloud导入json导入实例为vr (api_ VisualRecognitionV3 =‘apikey’，version='2016-05-20')，打开(‘./trucks.zip’，'rb')为卡车，\打开(‘./cars.zip’，'rb')为汽车: visual_recognition.create_classifier('CarsvsTrucks'，cars_positive_examples=cars，apikey
