Description

I want to split a single npy file read by fn.readers.numpy in 100-bit units according to the first dimension, is there any function available?

Contributor guide

Research direction
Check the DALI documentation and source code for existing operators that support chunking or splitting of numpy data along the first dimension. Look at fn.readers.numpy parameters like 'pad last batch' or 'batch size' and consider using 'fn.experimental.inputs' or 'fn.transforms' to achieve chunking. If no built in function exists, consider implementing a custom operator using fn.experimental.decorators.
