Querying a Dataset List

Obtain a dataset list by page.

list_datasets(session, dataset_type=None, dataset_name=None, offset=None, limit=None)

Sample Code

Example 1: Obtain a dataset list.

from modelarts.session import Session
from modelarts.dataset import Dataset
session = Session()
# Obtain a dataset list.
dataset_list = Dataset.list_datasets(session)
print(dataset_list) # Print the query result.

Example 2: Obtain a dataset list by dataset type.

# Obtain image classification datasets.
dataset_list = Dataset.list_datasets(session, dataset_type=0)
print(dataset_list)

Example 3: Obtain a dataset list by dataset name.

# Obtain the datasets with dataset contained in dataset names.
dataset_list = Dataset.list_datasets(session, dataset_name="dataset")
print(dataset_list)

Example 4: Obtain a dataset list by page.

# By default, 10 dataset records are returned at a time. You can set limit and offset for query by page.
dataset_list = Dataset.list_datasets(session, offset=0, limit=50) # Obtain the 1st to 50th records.
print(dataset_list)
dataset_list = Dataset.list_datasets(session, offset=1, limit=50) # Obtain the 51st to 100th records.
print(dataset_list)
