Andrej	f68ac2200d	Merge pull request #428 from kjslag/memmap-memory-leak ... fix np.memmap memory leak	2024-02-27 08:41:24 -08:00
Kevin Slagle	5156fef93c	fix np.memmap memory leak ... nn.memmap doesn't free memory that it accesses. Thus, the entire dataset gets stored in RAM as the dataset has been fully accessed. The simplest workaround on stackoverflow is to just recreate the memmap for each batch. The extra overhead is negligible. https://stackoverflow.com/questions/45132940/numpy-memmap-memory-usage-want-to-iterate-once/61472122#61472122	2024-01-25 11:41:01 -08:00

Oleksandr Kuvshynov	542ac51d1f	nanogpt: fix multiprocessing in load_dataset on os x ... The issue seems to be that _fixup_main_from_path in multiprocessing module in python is unable to find entry point, thus, adding ``` if __name__ == '__main__' ```	2023-06-17 20:35:38 -04:00
