一、准备工作

1.1 下载模型

Huggingface是一个开放的人工智能模型库，提供了大量经过预训练的模型供用户下载和使用。要下载模型访问Huggingface网站： https://huggingface.co/models。

如果huggingface无法下载，可以使用下面的地址下载：

• 模型下载地址：https://pan.quark.cn/s/a22f5a9e3490 （deepseek-r1-1.5b）
• 数据集准备：https://pan.quark.cn/s/a220f415b35c

确保模型目录 deepseekr1-1.5b 下包含以下关键文件：

config.json
pytorch_model.bin  # 或 model.safetensors（必须存在至少一个）
tokenizer.json     # 或其他分词器文件（如 tokenizer_config.json）

1.2 依赖安装

# 在安装命令后添加 -i 参数指定镜像源：
pip install transformers datasets -i https://mirrors.aliyun.com/pypi/simple/# Transformers 库需要依赖 PyTorch、TensorFlow 或 Flax 中的一个才能加载模型
# 通用安装命令（CPU版）
pip install torch
# 如果有NVIDIA显卡（CUDA，如果下载包无cuXXX后缀表示是CPU版本）
pip install torch torchvision torchaudio --index-url https://mirrors.aliyun.com/pypi/simple/# 其他依赖（device_map="auto"、quantization_config）
pip install bitsandbytes accelerate>=0.26.0 --index-url https://mirrors.aliyun.com/pypi/simple/# Windows 官方不提供预编译的 CUDA 版 bitsandbytes，windows场景：卸载现有版本，安装社区维护的预编译版本
# 关于其他版本可自行查看下载：https://github.com/jllllll/bitsandbytes-windows-webui/releases/
pip uninstall bitsandbytes -y
pip install https://github.com/jllllll/bitsandbytes-windows-webui/releases/download/wheels/bitsandbytes-0.43.0-py3-none-win_amd64.whl

ps：常用镜像源：

阿里云：https://mirrors.aliyun.com/pypi/simple/
豆瓣：  https://pypi.doubanio.com/simple/
华为云：https://repo.huaweicloud.com/repository/pypi/simple/

永久配置镜像源：

pip config set global.index-url  https://mirrors.aliyun.com/pypi/simple/
pip config list

查看 CUDA 版本（需提前安装 NVIDIA 驱动）：

nvidia-smi  # 右上角显示最高支持的 CUDA 版本（如 12.6）
