如果要为实际用例训练实际模型,则可能需要研究并可能优化其中一些参数。 """Fine TuningThis code is largly co-opted. In the absence of a rigid validationprocedure, the best practice is to just copy a successful tutorial or,better yet, directly from the documentation."""importtransformerstrainer=trans...
LoRA (Low-Rank Adaptation)方法是微软研究团队在2021年推出的一种微调方法。从那时起,它已经成为一种非常流行的方法来微调大型语言模型,扩散模型(例如用于图像生成)和其他类型的AI模型。 LoRA是一种参数有效微调(PEFT)Parameter-efficient Fine-tuning (PEFT)。 在本文中,我们将用简单的英语解释LoRA是如何工...

Stable Diffusion LoRA models can help you to produce fine-tuned output. Here's how to use these Stable Diffusion models.
Paste your config if you want more help but for memory you need 64GB RAM that is dedicated to the finetune ! I had to upgrade to 128GB my system, last time usage was 68GB for finetuning with 24GB VRAM, you should have those : ...
The obvious benefit of LoRA is that it makes fine-tuning a lot cheaper by reducing memory needs. It also reduces catastrophic forgetting and works better with small datasets. Figure 1: LoRA Explained During training, LoRA freezes the original weights W and fine-tunes two small ma...
