Introduction to Importing Data from OBS

Import Modes

You can import data from OBS through an OBS path or a manifest file.

OBS path: indicates that the dataset to be imported has been stored in an OBS path. In this case, select an OBS path that you can access. In addition, the directory structure in the OBS path must comply with the specifications. For details, see Specifications for Importing Data from an OBS Directory. This import mode is available only for the following types of datasets: Image classification, Object detection, Text classification, Table, and Sound classification. For other types of datasets, data can be imported only through a manifest file.
Manifest file: indicates that the dataset file is in the manifest format and the manifest file has been uploaded to OBS. The manifest file defines the mapping between labeling objects and content. For details about the specifications of manifest files, see Specifications for Importing a Manifest File.

Before importing an object detection dataset, ensure that the labeling range of the labeling file does not exceed the size of the original image. Otherwise, the import may fail.
