从python运行Forms Recognizer API时出现408错误

Question

我是Azure和Forms Recognizer的新手。我正在使用文档（python）中的示例代码。

我在同一地区拥有Forms Recognizer资源和培训文档。培训文档（5个单页PDF）本身位于Blob存储容器中（容器中没有其他文件）。运行该程序时，我得到以下信息：

Response status code: 408
Response body: {'error':
                   {'code': '1011',
                    'innerError': {'requestId': '7c88d722-8c2e-42e2-b248-edeebe467a85'},
                    'message': 'The operation exceeded allowed time limit and was canceled. The common reasons are that the data source is too large or contains unsupported content. Please check that your request conforms to service limits and retry with redacted data source.'}}

任何建议将不胜感激。
