Description
Similar to #415 , this code will split the dataset files into small pieces to avoid exceeding the memory limit of Ray, but this code requires users to run it in advance.
Usage
python tools/data_resplit.py --data-dir [path to source data] --resplit-dir [path to resplited dataset] [--ray-address [the address of the Ray cluster]]
