运行最低的显存要求大概是多少？我用RTX A4000 16GB 报显存不足

torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 14.00 MiB (GPU 0; 15.73 GiB total capacity; 15.12 GiB already allocated; 3.19 MiB free; 15.54 GiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation.
