LoRA概念

LoRA的全称是LoRA: Low-Rank Adaptation of Large Language Models，可以理解为stable diffusion（SD)模型的一种插件，和hyper-network，controlNet一样，都是在不修改SD模型的前提下，利用少量数据训练出一种画风/IP/人物，实现定制化需求，所需的训练资源比训练SD模要小很多，非常适合社区使用者和个人开发者。

故障

OutOfMemoryError

OutOfMemoryError: CUDA out of memory. Tried to allocate 450.00 MiB (GPU 0; 5.79 GiB total capacity; 3.13 GiB already allocated; 422.62 MiB free; 3.60 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

Time taken: 33.77s

Torch active/reserved: 3948/4000 MiB, Sys VRAM: 5796/5927 MiB (97.79%)

显卡内存顶不住了，缩小图片尺寸。说明：显存大小比显卡性能重要，显存不够直接崩溃，显卡性能差点顶多慢点。
