class mindspore.dataset.vision.py_transforms.ToType(output_type)[source]

Convert the input numpy.ndarray image to the desired dtype.

Parameters: output_type (numpy.dtype) – The desired dtype of the output image, e.g. numpy.float32.
Raises: TypeError – If the input image is not of type numpy.ndarray.

Supported Platforms:: CPU

Examples

>>> import numpy as np
>>> from mindspore.dataset.transforms.py_transforms import Compose
>>>
>>> transforms_list =Compose([py_vision.Decode(),
...                           py_vision.RandomHorizontalFlip(0.5),
...                           py_vision.ToTensor(),
...                           py_vision.ToType(np.float32)])
>>> # apply the transform to dataset through map function
>>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list,
...                                                 input_columns="image")
