WebApr 13, 2024 · 1. You are using unnecessarily large types. Some of your types are 64-bit, and you are mixing types, which is bad. Use a consistent 32-bit dtype throughout. That will cut your memory usage in half. Either int32 or float32 should be OK. 2. To cut your memory usage in half again, use the method here. http://www.idris.fr/eng/jean-zay/gpu/jean-zay-gpu-torch-multi-eng.html
