Creating a Dataset Import Task

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

dataset.import_data(path=None,  anntation_config=None, **kwargs)

Table 1 lists the import modes supported by datasets.

Sample Code

  • Example 1: Import an object detection dataset from an OBS path.
    from modelarts.session import Session
    from modelarts.dataset import Dataset
    session = Session()
    
    dataset = Dataset(session, dataset_id)
    annotation_config = dict()
    annotation_config['scene'] = "object_detection"
    annotation_config['format_name'] = "ModelArts PASCAL VOC 1.0"
    import_resp = dataset.import_data(path="/obs-gaia-test/data/image/image-detection/", annotation_config=annotation_config)
  • Example 2: Import an object detection dataset from a manifest file.
    annotation_config = dict()    # Task with data imported from a manifest file. annotation_config is used to import labels.
    import_resp = dataset.import_data(
                path="/obs-gaia-test/data/output/work_path/dataset-5932-Qdd1RUZ3wqBQrwrTr3v/annotation/V001/V001.manifest",annotation_config=annotation_config)
  • Example 3: Import a table dataset from an OBS path.
    import_resp = dataset.import_data(
                path="/obs-gaia-test/data/table/table1/", with_column_header=True)

Parameters

Table 2 Request parameters

Parameter

Mandatory

Type

Description

path

Yes

String

OBS path or manifest file path for importing data

  • If data is to be imported from a manifest file, ensure the manifest file is specified in the path.
  • If data is to be imported from an OBS path, ensure only image classification, object detection, image segmentation, text classification, sound classification, and table datasets are supported.
  • Newline characters (\n), carriage return characters (\r), and tab characters (\t) are not allowed.

annotation_config

No

Table 4

Data labeling format. If this parameter is set to None, no labels will be imported. If data is to be imported from a manifest file, import an empty dict object so that labels can be imported. The following labeling formats are supported:

  • Image classification
  • Object detection
  • Sound classification
  • Text classification

with_column_header

No

Boolean

Whether the first row of a table is the table header. This parameter is mandatory for table datasets.

  • True: The first row of a table is used as the table header.
  • False: The first row of a table is not used as the table header, but only as sample data.
