class mindspore.dataset.vision.py_transforms.RandomVerticalFlip(prob=0.5)[source]

Randomly flip the input PIL Image vertically with a given probability.

Parameters

prob (float, optional) – Probability of performing vertically flip. Default: 0.5.

Raises

TypeError – If prob is not of type float.
ValueError – If prob is not in range of [0, 1].
RuntimeError – If shape of input image is not <H, W> or <H, W, C>.

Supported Platforms:: CPU

>>> from mindspore.dataset.transforms.py_transforms import Compose
>>>
>>> transforms_list = Compose([py_vision.Decode(),

>>> # apply the transform to dataset through map function
>>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list,
