# 了解清单摘要
清单摘要包含以下信息。
+ 有关在验证期间发生的[终止性清单内容错误列表](tm-debugging.md#tm-error-category-combined-terminal)的错误信息。
+ 训练和测试数据集中的[非终止性 JSON 行验证错误列表](tm-debugging.md#tm-error-category-non-terminal-errors)的错误位置信息。
+ 错误统计信息，例如在训练和测试数据集中发现的无效 JSON 行总数。
如果没有[终止性清单文件错误列表](tm-debugging.md#tm-error-category-terminal)，则会在训练期间创建清单摘要。要获取清单摘要文件 (*manifest\$1summary.json*) 的位置，请参阅[获取验证结果](tm-debugging-getting-validation-data.md)。
**注意**
清单摘要中不会报告[服务错误](tm-debugging.md#tm-error-category-service)和[清单文件错误](tm-debugging.md#tm-error-category-terminal)。有关更多信息，请参阅 [终止性错误](tm-debugging.md#tm-error-categories-terminal)。
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](tm-debugging-aggregate-errors.md)。
## 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。
+ `training`：训练数据集中的统计信息和发现的错误。
+ `testing`：测试数据集中的统计信息和发现的错误。
`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](tm-debugging-fixing-validation-errors.md)。
### 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\$1INSUFFICIENT\$1USABLE\$1LABEL\$1OVERLAP](tm-debugging-aggregate-errors.md#tm-error-ERROR_INSUFFICIENT_USABLE_LABEL_OVERLAP)。
