RuntimeError: CUDA out of memory #151
Description
RuntimeError: CUDA out of memory. Tried to allocate 256.00 MiB (GPU 0; 22.38 GiB total capacity; 21.52 GiB already allocated; 245.94 MiB free; 21.55 GiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation. See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF
when I used 4GPUs (P40),I got the error above. What could I do ? Is P40 suitable for this project?
