WatsonApiException：错误：预览API已于2019-09-30删除

Question

我正在尝试使用下面的代码访问IBM Watson Discovery API（免费试用）：

with open(filename, "r") as f:
    res = discovery.test_configuration_in_environment(environment_id=env_id, configuration_id=cfg_id, file=f).get_result()

您可以在此处查看完整的代码文件：https://github.com/udacity/AIND-NLP-Bookworm/blob/master/bookworm.ipynb。运行此程序时出现以下错误：

WatsonApiException: Error: The Preview API was removed on 2019-09-30., Code: 410 , X-dp-watson-tran-id: 569fbd407a75c23f850522571bddee26 , X-global-transaction-id: 569fbd407a75c23f850522571bddee26

任何已知的解决方法？

Answer 1

[根据发行说明和响应，您看到的Preview API已于2019年6月4日弃用-https://cloud.ibm.com/docs/discovery?topic=discovery-release-notes#4jun19-并于2019年9月30日被删除-https://cloud.ibm.com/docs/discovery?topic=discovery-release-notes

发现API仍然可用-https://cloud.ibm.com/apidocs/discovery/discovery，但不是预览方法。
