torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 7.66 GiB (GPU 0; 8.00 GiB total capacity; 809.64 MiB already allocated; 5.02 GiB free; 1.18 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

이거 떴는데 알아보니 배치 사이즈 줄이면 되는 것 같은데 배치 사이즈를 어디서 줄임? 개초보임.
