def mx.io.np2rec(data, labels, transforms, dataset_params):
"""
Convert numpy representation of images to binary files.
Input Parameters -
----------
data - numpy array holding all the image data.
Supported array shapes -
(N,H,W) - image with uint8 data
(N,3,H,W) - image with RGB values (float or uint8)
(N,4,H,W) - image with RGBA values.
N is the number of the images.
H and W are the rows and columns of the image.
The pixel values should be in the range of [0...1] for float data type and [0...255] for int data type. Values outside this range will be clipped.
labels - numpy array holding labels for each of the images. Should be of length N.
transforms - gluon.transforms.Compose object
dataset_params - dict object whose description is given in the appendix
output_path - string object containing the path to the output location
Return type -
----------
rec_file_path - str object depicting the path of the output rec file
"""

Backward Compatibility
Post implementing the API the existing CLI tool will continue to exist, but users will also be directed to the new API and its accompanying documentation/tutorials.
