# Understanding the manifest summary
The manifest summary contains the following information.
+ Error information about [List of terminal manifest content errors](tm-debugging.md#tm-error-category-combined-terminal) encountered during validation.
+ Error location information for [List of non-terminal JSON line validation errors](tm-debugging.md#tm-error-category-non-terminal-errors) in the training and testing datasets.
+ Error statistics such as the total number of invalid JSON Lines found in the training and testing datasets.
The manifest summary is created during training if there are no [List of terminal manifest file errors](tm-debugging.md#tm-error-category-terminal). To get the location of the manifest summary file (*manifest\$1summary.json*), see [Getting the validation results](tm-debugging-getting-validation-data.md).
**Note**
[Service errors](tm-debugging.md#tm-error-category-service) and [manifest file errors](tm-debugging.md#tm-error-category-terminal) are not reported in the manifest summary. For more information, see [Terminal errors](tm-debugging.md#tm-error-categories-terminal).
For information about specific manifest content errors, see [Terminal manifest content errors](tm-debugging-aggregate-errors.md).
## Manifest summary file format
A manifest file has 2 sections, `statistics` and `errors`.
### statistics
`statistics` contains information about the errors in the training and testing datasets.
+ `training` – statistics and errors found in the training dataset.
+ `testing` – statistics and errors found in the testing dataset.
Objects in the `errors` array contain the error code and message for manifest content errors. ``
The `error_line_indices` array contains the line numbers for each JSON Line in the training or test manifest that has an error. For more information, see [Fixing training errors](tm-debugging-fixing-validation-errors.md).
### errors
Errors spanning both the training and testing dataset. For example, an [ERROR\$1INSUFFICIENT\$1USABLE\$1LABEL\$1OVERLAP](tm-debugging-aggregate-errors.md#tm-error-ERROR_INSUFFICIENT_USABLE_LABEL_OVERLAP) occurs when there is isn't enough usable labels that overlap the training and testing datasets.
```
{
"statistics": {
"training":
{
"use_case": String, # Possible values are IMAGE_LEVEL_LABELS, OBJECT_LOCALIZATION and NOT_DETERMINED
"total_json_lines": Number, # Total number json lines (images) in the training manifest.
"valid_json_lines": Number, # Total number of JSON Lines (images) that can be used for training.
"invalid_json_lines": Number, # Total number of invalid JSON Lines. They are not used for training.
"ignored_json_lines": Number, # JSON Lines that have a valid schema but have no annotations. The aren't used for training and aren't counted as invalid.
"error_json_line_indices": List[int], # Contains a list of line numbers for JSON line errors in the training dataset.
"errors": [

"ignored_json_lines": Number, # JSON Lines that have a valid schema but have no annotations. They aren't used for testing and aren't counted as invalid.
"error_json_line_indices": List[int], # contains a list of error record line numbers in testing dataset.

## Example manifest summary
The following example is a partial manifest summary that shows a terminal manifest content error ([ERROR\$1TOO\$1MANY\$1INVALID\$1ROWS\$1IN\$1MANIFEST](tm-debugging-aggregate-errors.md#tm-error-ERROR_TOO_MANY_INVALID_ROWS_IN_MANIFEST)). The `error_json_line_indices` array contains the line numbers of non-terminal JSON Line errors in the corresponding training or testing validation manifest.
```
{
"errors": [],
"statistics": {
"training": {
"use_case": "NOT_DETERMINED",
"total_json_lines": 301,
"valid_json_lines": 146,
"invalid_json_lines": 155,
"ignored_json_lines": 0,
"errors": [
{
"code": "ERROR_TOO_MANY_INVALID_ROWS_IN_MANIFEST",
"message": "The manifest file contains too many invalid rows."
}
],
