我严格按照README安装了相关的包 pip install -r requirements.txt pip install git+https://github.com/unslothai/unsloth.git pip install bitsandbytes==0.43.1 pip install peft==0.10.0 pip install torch==2.2.2 pip install xformers==0.0.25.post1 启动参数

export CUDA_VISIBLE_DEVICES=2,3,4,5,6,7
torchrun --nproc_per_node=6 train.py \
               --train_args_file train_args/sft/qlora/llama3-8b-sft-qlora.json

我使用了6xA800 ValueError: You can't train a model that has been loaded in 8-bit precision on a different device than the one you're training on. Make sure you loaded the model on th e correct device using for exampledevice_map={'':torch.cuda.current_device() or device_map={'':torch.xpu.current_device()}` 这个错误是为什么呢

能看看train_args么

似乎是accelerate本身的问题，我不用unsloth就没有问题。
