filename (str) – The path to the file to be written.
data (Union[numpy.ndarray, mindspore.Tensor]) – The one dimension uint8 data to be written.

Raises

TypeError – If filename is not of type str.
TypeError – If data is not of type numpy.ndarray or mindspore.Tensor.
RuntimeError – If the filename is not a common file.
RuntimeError – If the data type of data is not uint8.

Examples

>>> import mindspore.dataset.vision as vision
>>> import numpy as np
>>> # Generate a random data with 1024 bytes
>>> data = np.random.randint(256, size=(1024), dtype=np.uint8)
>>> vision.write_file("/path/to/file", data)
