Web@kmaehashi thank you for your comment. Sorry for being slow on this, I followed exactly this explanation that you shared as well: # When the array goes out of scope, the allocated device memory is released # and kept in the pool for future reuse. a = None # (or del a) Since I will reuse the same size array. Why does it work inconsistently. WebSep 4, 2024 · When using cupy, cupy takes up a lot of memory by default (about 3.8G in my program), which is quite a waste of space. I would like to know how to set it to reduce this default memory usage. To Reproduce

Thank you for trying. Hmm, I will investigate. cupy.cuda.set_pinned_memory_allocator is used to cache a pinned host (CPU) memory, not GPU memory. cupy.cuda.memory is not a module for pinned memory, so pinned memory allocator is probably not related with this problem.
