tf.keras.utils.array_to_img(
    x, data_format=None, scale=True, dtype=None
)

Usage:

from PIL import Image
img = np.random.random(size=(100, 100, 3))
pil_img = tf.keras.preprocessing.image.array_to_img(img)

Args
x	Input data, in any form that can be converted to a Numpy array.
data_format	Image data format, can be either "channels_first" or "channels_last". Defaults to None, in which case the global setting tf.keras.backend.image_data_format() is used (unless you changed it, it defaults to "channels_last").
scale	Whether to rescale the image such that minimum and maximum values are 0 and 255 respectively. Defaults to True.
dtype	Dtype to use. Default to None, in which case the global setting tf.keras.backend.floatx() is used (unless you changed it, it defaults to "float32")

Returns
A PIL Image instance.

Raises
ImportError	if PIL is not available.
ValueError	if invalid x or data_format is passed.
