An image_tensor() object that is a super thin wrapper around a 4D
base::array(), representing image data in the format "b h w c"
(batch, height, width, channels). The actual image data is 6 black letters
on differently colored backgrounds, spelling out the word "einops". When
printing this object in the terminal it will automatically plot the images.
To subset, use the [ operator, and when used with a single index, it
will return a single image tensor.
Format
An image_tensor() object with 6 images, each of size 96 x 96
pixels, with 3 color channels (RGB). The images are stored in a 4D array
with dimensions (6, 96, 96, 3).
