RuntimeError: CUDA out of memory.

训练的时候出现错误“RuntimeError: CUDA out of memory. Tried to allocate 20.00 MiB (GPU 0; 7.92 GiB total capacity; 6.76 GiB already allocated; 66.50 MiB free; 6.87 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" 将BANTCH_SIZE设置为1依旧显示该错误，请问作者有解决的方案吗？
