Exporting Data

A dataset includes labeled and unlabeled data. You can select images or filter data based on the filter criteria and export to a new dataset or the specified OBS directory. In addition, you can view the task history to learn about the export records.

Only datasets of image classification, object detection, image segmentation, and free format types can be exported.

  • For image classification datasets, only the label files in TXT format can be exported.
  • For object detection datasets, only XML label files in Pascal VOC format can be exported.
  • For image segmentation datasets, only XML label files in Pascal VOC format and mask images can be exported.
  • For free format datasets, all files of the datasets can be exported.

Exporting Data to a New Dataset

  1. Log in to the ModelArts management console. In the left navigation pane, choose Data Management > Datasets. The Datasets page is displayed.
  2. In the dataset list, select the dataset of the object detection or image classification type and click the dataset name to go to the Dashboard tab page of the dataset.

    For a dataset of the free format type, you can click the dataset name to directly access the dataset details page and go to 4.

  3. On the Dashboard page of the dataset, click Label in the upper right corner. The dataset details page is displayed.
  4. On the dataset details page, select or filter data to be exported. Click Export To and choose New Dataset from the drop-down list.

  5. In the displayed Export to New Dataset dialog box, enter the related information and click OK.

    Name: name of the new dataset

    Storage Path: input path of the new dataset, that is, the OBS path where the data to be exported is stored

    Output Path: output path of the new dataset, that is, the output path after labeling is complete. The output path cannot be the same as the storage path, and the output path cannot be a subdirectory of the storage path.

    Export Content: The options are Export the selected samples and Export all samples meeting filtering criteria.

    Hard Example Filtering: Select whether to enable hard example filtering.

  5. In the displayed Export to OBS dialog box, enter the related information and click OK.

    Storage Path: path where the data to be exported is stored. You are advised not to save data to the input or output path of the current dataset.

    Export Content: The options are Export the selected samples and Export all samples meeting filtering criteria.

    Hard Example: Select whether to enable hard examples.

Viewing the Task History

When you export data to a new dataset or OBS, you can view the export task details in the View Task History dialog box.

  1. Log in to the ModelArts management console. In the left navigation pane, choose Data Management > Datasets. The Datasets page is displayed.
  2. In the dataset list, select the dataset of the object detection or image classification type and click the dataset name to go to the Dashboard tab page of the dataset.

    For a dataset of the free format type, you can click the dataset name to directly access the dataset details page and go to 4.

  3. On the Dashboard page of the dataset, click Label in the upper right corner. The dataset details page is displayed.
  4. On the dataset details page, select or filter data to be exported. Click Export To and choose View Task History from the drop-down list.
  5. In the View Task History dialog box, view the export task history of the current dataset. Information about Task ID, Created, Type, Path, Total, and Status is included.
