书生·浦语大模型实战营之XTuner 微调个人小助手认知
在本节课中讲一步步带领大家体验如何利用 XTuner 完成个人小助手的微调！
为了能够让大家更加快速的上手并看到微调前后对比的效果， 用 QLoRA 的方式来微调一个自己的小助手！ 可以通过下面两张图片来清楚的看到两者的对比。
- 微调前
- 微调后
可以看到，微调后的大模型能够被调整成想要的效果，下面让我们一步步的来实现这个有趣的过程吧！
开发机准备
InternStudio 中创建一个开发机进行使用
完成准备工作后我们就可以正式开始我们的微调之旅啦！
通过下面这张图来简单了解一下 XTuner 的运行原理
-
环境安装：若欲运用XTuner这一款操作简便、易于掌握的模型微调工具包进行模型微调任务，首当其冲的步骤便是对其进行安装。
-
前期准备：在顺利完成安装之后，接下来的关键环节是明确自身的微调目标。应深入思考期望通过微调实现何种具体功能，以及自身具备哪些硬件资源与数据支持。倘若已拥有与特定任务相关的数据集，且计算资源充足，那么微调工作自然能够顺利展开，正如OpenAI所展现的那样。然而，对于普通开发者而言，面对有限的资源条件，可能需要着重考虑如何有效地采集数据，以及采用何种策略与方法以提升模型性能。
-
启动微调：在确定微调目标之后，用户可在XTuner的配置库中检索并选取适宜的配置文件，进行相应修改。修改完毕后，只需一键启动训练过程即可。此外，训练得到的模型仅需在终端输入一行指令，便能便捷地完成模型转换与部署作业。
环境安装
# 如果你是在 InternStudio 平台，则从本地 clone 一个已有 pytorch 的环境：
# pytorch 2.0.1 py3.10_cuda11.7_cudnn8.5.0_0
studio-conda xtuner0.1.17
# 如果你是在其他平台：
# conda create --name xtuner0.1.17 python=3.10 -y
# 激活环境
conda activate xtuner0.1.17
# 进入家目录 （~的意思是 “当前用户的home路径”）
cd ~
# 创建版本文件夹并进入，以跟随本教程
mkdir -p /root/xtuner0117 && cd /root/xtuner0117
# 拉取 0.1.17 的版本源码
git clone -b v0.1.17 https://github.com/InternLM/xtuner
# 无法访问github的用户请从 gitee 拉取:
# git clone -b v0.1.15 https://gitee.com/Internlm/xtuner
# 进入源码目录
cd /root/xtuner0117/xtuner
# 从源码安装 XTuner
pip install -e '.[all]'
数据集准备
为了使模型能够明确自身的身份地位，并在被问及自身身份时以期望的方式作出回应，需要在微调数据集中大量引入这类数据。
首先，需要创建一个文件夹，用以存放此次训练所需的所有文件。
# 前半部分是创建一个文件夹，后半部分是进入该文件夹。
mkdir -p /root/ft && cd /root/ft
# 在ft这个文件夹里再创建一个存放数据的data文件夹
mkdir -p /root/ft/data && cd /root/ft/data
在 data 目录下新建一个 generate_data.py 文件
import json
# 设置用户的名字
name = '段老师'
# 设置需要重复添加的数据次数
n = 10000
# 初始化OpenAI格式的数据结构
data = [
{
"messages": [
{
"role": "user",
"content": "请做一下自我介绍"
},
{
"role": "assistant",
"content": "我是{}的小助手，内在是上海AI实验室书生·浦语的1.8B大模型哦".format(name)
}
]
}
]
# 通过循环，将初始化的对话数据重复添加到data列表中
for i in range(n):
data.append(data[0])
# 将data列表中的数据写入到一个名为'personal_assistant.json'的文件中
with open('personal_assistant.json', 'w', encoding='utf-8') as f:
# 使用json.dump方法将数据以JSON格式写入文件
# ensure_ascii=False 确保中文字符正常显示
# indent=4 使得文件内容格式化，便于阅读
json.dump(data, f, ensure_ascii=False, indent=4)
运行 generate_data.py 文件
# 确保先进入该文件夹
cd /root/ft/data
# 运行代码
python /root/ft/data/generate_data.py
查询personal_assistant.json文件
模型准备
在准备好了数据集后， 使用 InternLM 最新推出的小模型 InterLM-chat-1.8B 来完成此次的微调演示。
# 创建目标文件夹，确保它存在。
# -p选项意味着如果上级目录不存在也会一并创建，且如果目标文件夹已存在则不会报错。
mkdir -p /root/ft/model
# 复制内容到目标文件夹。-r选项表示递归复制整个文件夹。
cp -r /root/share/new_models/Shanghai_AI_Laboratory/internlm2-chat-1_8b/* /root/ft/model/
model 文件夹下保存了模型的相关文件和内容

(xtuner0.1.17) root@intern-studio-061925:~/ft/data#
配置文件选择
在准备好了模型和数据集后， 根据 选择的微调方法方法 查找最匹配的配置文件
XTuner 提供多个开箱即用的配置文件，用户可以通过下列命令查看：
# 列出所有内置配置文件
# xtuner list-cfg
# 假如我们想找到 internlm2-1.8b 模型里支持的配置文件
xtuner list-cfg -p internlm2_1_8b
目前只有两个支持 internlm2-1.8B 的模型配置文件
(xtuner0.1.17) root@intern-studio-061925:~/ft/data# xtuner list-cfg -p internlm2_1_8b
==========================CONFIGS===========================
PATTERN: internlm2_1_8b
-------------------------------
internlm2_1_8b_full_alpaca_e3
internlm2_1_8b_qlora_alpaca_e3
=============================================================
(xtuner0.1.17) root@intern-studio-061925:~/ft/data#
配置文件名的解释
以 internlm2_1_8b_qlora_alpaca_e3 举例：
尽管使用的数据集并非alpaca，而是我们自己通过脚本精心制作的小助手数据集，但鉴于采用QLoRA方法对internlm-chat-1.8b模型进行微调，最匹配的配置文件应当是internlm2_1_8b_qlora_alpaca_e3。因此，可以选择将该配置文件复制到当前目录，以便进行微调工作。
# 创建一个存放 config 文件的文件夹
mkdir -p /root/ft/config
# 使用 XTuner 中的 copy-cfg 功能将 config 文件复制到指定的位置
xtuner copy-cfg internlm2_1_8b_qlora_alpaca_e3 /root/ft/config
在 /root/ft/config 文件夹下有一个名为 internlm2_1_8b_qlora_alpaca_e3_copy.py 的文件
(xtuner0.1.17) root@intern-studio-061925:~/ft/data# ls /root/ft/config/internlm2_1_8b_qlora_alpaca_e3_copy.py

在微调过程中，最为关键的是准备一份高质量的数据集，这无疑是影响微调效果最为核心的要素。
微调过程常被人们称为“炼丹”，意在强调炼丹过程中的材料选择、火候控制、时间把握以及丹炉的选择都至关重要。在此比喻中，可以将XTuner视为炼丹的丹炉，只要其质量可靠，不会在炼丹过程中出现问题，一般而言便能够顺利进行。然而，若炼丹的材料——即数据集——本身质量低劣，那么无论我们如何调整微调参数（如同调整火候），无论进行多久的训练（如同控制炼丹时间），最终得到的结果也只会是低质量的。只有当使用了优质的材料，才可以进一步考虑炼丹的时间和方法。因此，学会构建高质量的数据集显得尤为重要。

As a workaround, the current "builder" registry in "xtuner" is used to build instance. This may cause unexpected failure when running the built modules. Please check whether "mmengine" is a correct scope, or whether the registry is initialized.
`low_cpu_mem_usage` was None, now set to True since model is quantized.

使用 deepspeed 来加速训练
除此之外，也可以结合 XTuner 内置的 deepspeed 来加速整体的训练过程，共有三种不同的 deepspeed 类型可进行选择，分别是 deepspeed_zero1, deepspeed_zero2 和 deepspeed_zero3
DeepSpeed优化器及其选择方法
DeepSpeed是一个深度学习优化库，由微软开发，旨在提高大规模模型训练的效率和速度。它通过几种关键技术来优化训练过程，包括模型分割、梯度累积、以及内存和带宽优化等。DeepSpeed特别适用于需要巨大计算资源的大型模型和数据集。
在DeepSpeed中，zero 代表“ZeRO”（Zero Redundancy Optimizer），是一种旨在降低训练大型模型所需内存占用的优化器。ZeRO 通过优化数据并行训练过程中的内存使用，允许更大的模型和更快的训练速度。ZeRO 分为几个不同的级别，主要包括：
deepspeed_zero1：这是ZeRO的基本版本，它优化了模型参数的存储，使得每个GPU只存储一部分参数，从而减少内存的使用。
deepspeed_zero2：在deepspeed_zero1的基础上，deepspeed_zero2进一步优化了梯度和优化器状态的存储。它将这些信息也分散到不同的GPU上，进一步降低了单个GPU的内存需求。
deepspeed_zero3：这是目前最高级的优化等级，它不仅包括了deepspeed_zero1和deepspeed_zero2的优化，还进一步减少了激活函数的内存占用。这通过在需要时重新计算激活（而不是存储它们）来实现，从而实现了对大型模型极其内存效率的训练。
选择哪种deepspeed类型主要取决于你的具体需求，包括模型的大小、可用的硬件资源（特别是GPU内存）以及训练的效率需求。一般来说：
如果你的模型较小，或者内存资源充足，可能不需要使用最高级别的优化。
如果你正在尝试训练非常大的模型，或者你的硬件资源有限，使用deepspeed_zero2或deepspeed_zero3可能更合适，因为它们可以显著降低内存占用，允许更大模型的训练。
选择时也要考虑到实现的复杂性和运行时的开销，更高级的优化可能需要更复杂的设置，并可能增加一些计算开销。

可以看到，通过 deepspeed 来训练后得到的权重文件和原本的权重文件是有所差别的，原本的仅仅是一个 .pth 的文件，而使用了 deepspeed 则是一个名字带有 .pth 的文件夹，在该文件夹里保存了两个 .pt 文件。当然这两者在具体的使用上并没有太大的差别，都是可以进行转化并整合。
