运行微调时报错“torch.cuda.OutOfMemoryError: CUDA out of memory. ”

[alfiy]

运行微调时出现如下报错信息：
torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 14.48 GiB. GPU has a total capacity of 23.68 GiB of which 1.51 GiB is free. Including non-PyTorch memory, this process has 22.16 GiB memory in use. Of the allocated memory 21.79 GiB is allocated by PyTorch, and 18.10 MiB is reserved by PyTorch but unallocated. If reserved but unallocated memory is large try setting PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True to avoid fragmentation. See documentation for Memory Management (https://pytorch.org/docs/stable/notes/cuda.html#environment-variables)

我的是双GPU GTX3090

这是我的训练参数
