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
