了解清单摘要

清单摘要包含以下信息。

如果没有终止性清单文件错误列表，则会在训练期间创建清单摘要。要获取清单摘要文件 (manifest_summary.json) 的位置，请参阅获取验证结果。

有关特定清单内容错误的信息，请参阅终止性清单内容错误。

清单摘要文件格式

清单文件包含 2 个部分：statistics 和 errors。

statistics

statistics 包含有关训练和测试数据集中错误的信息。

errors 数组中的对象包含清单内容错误的错误代码和错误消息。

error_line_indices 数组包含训练或测试清单中存在错误的每个 JSON 行的行号。有关更多信息，请参阅 修复训练错误。

错误

跨越训练和测试数据集的错误。例如，当没有足够的可用标签与训练和测试数据集重叠时，就会发生 ERROR_INSUFFICIENT_USABLE_LABEL_OVERLAP。
