Examples

>>> import mindspore.dataset as ds
>>>
>>> dataset_dir1 = "path/to/imagefolder_directory1"
>>> dataset_dir2 = "path/to/imagefolder_directory2"
>>> ds1 = ds.ImageFolderDataset(dataset_dir1, num_parallel_workers=8)
>>> ds2 = ds.ImageFolderDataset(dataset_dir2, num_parallel_workers=8)
>>>
>>> # Create a dataset which is the combination of ds1 and ds2
>>> data = ds.zip((ds1, ds2))
