mindspore.dataset.vision.py_transforms.ToType

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

Convert the input NumPy image array to desired NumPy dtype.

Parameters: output_type (NumPy datatype) – The datatype of the NumPy output, e.g. numpy.float32.

Examples

>>> from mindspore.dataset.transforms.py_transforms import Compose
>>> import numpy as np
>>> 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")
