LoRA训练Mistral失败

一、问题现象（附报错日志上下文）：
使用fastchat的LoRA训练Mistral，报错NotImplementedError: Could not run 'npu::npu_format_cast' with arguments from the 'CPU' backend.

二、软件版本:
-- CANN 版本 : 社区版Ascend-cann-toolkit_7.0.0.alpha001_linux-aarch64.run
--Tensorflow/Pytorch/MindSpore 版本: torch2.1.0
--Python 版本 (e.g., Python 3.7.5): 3.9.18
--操作系统版本 (e.g., Ubuntu 18.04): ubuntu 20.04
--卡：910B

三、测试步骤：

```shell
git clone https://github.com/lm-sys/FastChat.git
cd FastChat
pip install git+https://github.com/microsoft/DeepSpeed.git@master
pip install git+https://github.com/huggingface/accelerate.git@main
