mindspore.dataset.transforms.c_transforms.PadEnd

class mindspore.dataset.transforms.c_transforms.PadEnd(pad_shape, pad_value=None)[source]

Pad input tensor according to pad_shape, input tensor needs to have same rank.

Parameters

pad_shape (list(int)) – List of integers representing the shape needed. Dimensions that set to None will not be padded (i.e., original dim will be used). Shorter dimensions will truncate the values.
pad_value (Union[str, bytes, int, float, bool]), optional) – Value used to pad. Default to 0 or empty string in case of tensors of strings.

Examples

>>> # Data before
>>> # |   col   |
>>> # +---------+
>>> # | [1,2,3] |
>>> # +---------|
>>> data = [[1, 2, 3]]
>>> numpy_slices_dataset = ds.NumpySlicesDataset(data, ["col"])
>>> numpy_slices_dataset = numpy_slices_dataset.map(operations=c_transforms.PadEnd(pad_shape=[4],
...                                                                                pad_value=10))
>>> # Data after
>>> # |    col     |
>>> # +------------+
>>> # | [1,2,3,10] |
>>> # +------------|
