+
+
+
+
+## 环境搭建
+
+本项目使用 [xtuner](https://github.com/InternLM/xtuner) 训练,在 [internlm2-chat-7b](https://huggingface.co/internlm/internlm2-chat-7b) 上进行微调
+
+1. clone 本项目
+
+```bash
+git clone https://github.com/PeterH0323/Streamer-Sales.git
+cd Streamer-Sales
+```
+
+2. 创建虚拟环境
+
+```bash
+conda env create -f environment.yml
+conda activate streamer-sales
+pip install -r requirements-raw.txt
+```
+
+## 数据集准备
+
+本模型的数据集构建采用了 通义千问 & 文心一言 生成数据集,相关的配置详见 `dataset/gen_dataset/conversation_cfg.yaml`。
+
+**训练本模型的数据集的生成方式,以及数据集已开源,详见 `dataset` 文件夹**
+
+下面介绍如何用商用大模型生成自由数据集:
+
+1. 获取模型的 api key,填入 `dataset/gen_dataset/api_cfg.yaml` 对应的位置
+
+2. 数据集生成配置文件 `dataset/gen_dataset/conversation_cfg.yaml` 介绍
+
+```yaml
+# 对话设置
+conversation_setting:
+
+ each_product_gen: 3 # 每个产品调取3次,产生一些随机话题
+
+ each_conversation_qa: 5 # 每个话题生成的对话数量
+
+ # 数据集配置
+ system: "现在你是一位金牌带货主播,你的名字叫{role_type},你的说话方式是{character}。你能够根据产品信息讲解产品并且结合商品信息解答用户提出的疑问。"
+ first_input: "我的{product_info},你需要根据我给出的商品信息撰写一段直播带货口播文案。你需要放大商品的亮点价值,激发用户的购买欲。"
+
+ dataset_gen_prompt: 现在你是一位金牌带货主播,你的名字叫{role_type},你的说话方式是{character}。
+ 我的{product_info},你需要根据我给出的商品信息撰写一段至少600字的直播带货口播文案。你需要放大商品的亮点价值,激发用户的购买欲。
+ 输出文案后,结合商品信息站在消费者的角度根据[{customer_question}]提出{each_conversation_qa}个问题并解答。
+ 全部输出的信息使用我期望的 json 格式进行输出:{dataset_json_format}。注意 json 一定要合法。
+
+ dataset_json_format:
+ '{
+ "conversation": [
+ {
+ "output": 直播带货口播文案,格式化一行输出,不要换行。
+ },
+ {
+ "input": 消费者的问题,
+ "output": 主播回答
+ },
+ {
+ "input": 消费者的问题,
+ "output": 主播回答
+ },
+ ... 直到问题结束
+ ]
+ }'
+
+# 角色及其性格
+role_type:
+ 乐乐喵:
+ - 甜美
+ - 可爱
+ - 熟练使用各种网络热门梗造句
+ - 称呼客户为[家人们]
+ 霸道总裁:
+ - 有专业素养
+ - 强势领导力
+ 有文化底蕴的文人:
+ - 优雅
+ - 有艺术感
+ - 必要时引经据典
+
+# 商品信息结构体
+product_info_struct:
+ - 商品名是[{name}],
+ - 商品的亮点是[{highlights}]
+
+# prompt: 购买东西时候,客户常会问题的问题,举例10个, 只列举大类就行
+customer_question_type:
+ - 价格与优惠政策
+ - 产品质量与性能
+ - 尺寸与兼容性
+ - 售后服务
+ - 发货与配送
+ - 用户评价与口碑
+ - 包装与附件
+ - 环保与安全
+ - 版本与型号选择
+ - 库存与补货
+
+# 第一个 prompt: 帮我列举10种常用的消费品种类,并每种举例5个其子类
+# 每个类 prompt: 现在你精通任何产品,你可以帮我举例每个产品的6个亮点或特点,, 然后用python dict形式输出:{类名:[特点1, 特点2] ...} ,去掉特点12的字样,除python字典外的其他都不要输出,不要有任何的警告信息。 [xxx]
+product_list:
+ 个人护理与美妆: # 商品大类
+ 口腔护理: # 商品子类
+ 漱口水: [深度清洁, 消除口臭, 抗菌消炎, 提神醒齿, 旅行装方便, 口感舒适] # 子类列举商品名,及其特点距离
+ 牙刷: [软毛设计, 有效清洁, 不同刷头适应不同需求, 防滑手柄, 定期更换刷头, 便携式包装]
+ 牙线: [清除牙缝食物残渣, 预防牙周病, 细密设计适合各种牙缝, 便于携带, 独立包装卫生, 无损牙齿表面]
+ 牙膏: [清洁牙齿, 防止蛀牙, 清新口气, 多种口味选择, 易于携带, 温和不刺激]
+ ...
+```
+
+> [!NOTE]
+> 温馨提示
+>
+> 别让大模型大量生成严格格式的数据,JSON 首当其冲,prompt 提示词用得不好,很容易会出现 JSON 解析错误,导致 Api Token 白花了,最好是生成特定的文本格式,然后用正则去取用
+
+3. 使用脚本可以进行生成:
+
+model_type 可以是通义千问(qwen)、文心一言(ernie)
+
+```bash
+cd dataset/gen_dataset
+python gen_dataset.py ${model_type}
+```
+
+执行之后,会在 `dataset/trainval_dataset/response` 生成对应模型的数据集
+
+```bash
+./dataset/trainval_dataset/response
+├── ernie_乐乐喵_train.json
+└── qwen_乐乐喵_train.json
+```
+
+3. 进行数据清洗并合并,以及生成自我认知数据
+
+```bash
+python merge_dataset.py dataset/trainval_dataset/response dataset/trainval_dataset/train.jsonl
+```
+
+生成之后可以在 ${output_path} 设置的路径看到 jsonl 文件,脚本会自动加上 conversion 的个数,例如 `1479_train.jsonl` ,jsonl 数据集样例如下:
+
+```json

+
+
+## 训练
+
+1. 将 `./finetune_configs/internlm2_chat_7b/internlm2_chat_7b_qlora_custom_data.py` 中 数据集路径 和 模型路径 改为您的本地路径
+
+```diff
+# Model
+- pretrained_model_name_or_path = 'internlm/internlm2-7b'
++ pretrained_model_name_or_path = '/path/to/internlm/internlm2-7b' # 这步可选,如果事先下载好了模型可以直接使用绝对路径
+
+# Data
+- data_path = 'timdettmers/openassistant-guanaco'
++ data_path = '/path/to/data.jsonl' # 数据集步骤生成的 json 文件绝对路径
+prompt_template = PROMPT_TEMPLATE.default
+max_length = 2048
+pack_to_max_length = True
+```
+
+3. 使用命令进行训练:
+
+```bash
+xtuner train finetune_configs/internlm2_chat_7b/internlm2_chat_7b_qlora_custom_data.py --deepspeed deepspeed_zero2
+```
+
+注意:如果显存不够了,调小一点 `batch_size` 和 `max_length`,反之还剩很多,调大这两个值
+
+## 部署
+
+### Web 部署 Demo
+
+1. 将 pth 转为 hf
+
+```bash
+xtuner convert pth_to_hf ./finetune_configs/internlm2_chat_7b_qlora_custom_data.py \
+ ./work_dirs/internlm2_chat_7b_qlora_custom_data/iter_340.pth \
+ ./work_dirs/internlm2_chat_7b_qlora_custom_data/iter_340_hf
+```
+
+2. 将微调后的模型和源模型 merge 生成新的模型
+
+```bash
+export MKL_SERVICE_FORCE_INTEL=1 # 解决 Error: mkl-service + Intel(R) MKL: MKL_THREADING_LAYER=INTEL is incompatible with libgomp.so.1 library.
+xtuner convert merge /path/to/internlm2-chat-7b \
+ ./work_dirs/internlm2_chat_7b_qlora_custom_data/iter_340_hf \
+ ./work_dirs/internlm2_chat_7b_qlora_custom_data/iter_340_merge
+```
+
+3. 启动 web demo
+
+```bash
+streamlit run app.py --server.address=0.0.0.0 --server.port 7860
+```
+
+
+
+### LMDeploy
+
+1. 安装 lmdeploy
+
+```bash
+pip install lmdeploy[all]==0.4.0
+```
+
+2. 进行 4bit 量化
+
+```bash
+lmdeploy lite auto_awq ./work_dirs/internlm2_chat_7b_qlora_custom_data/iter_340_merge \
+ --work-dir ./work_dirs/internlm2_chat_7b_qlora_custom_data/iter_340_merge_4bit
+```
+
+3. 测试速度
+
+```bash
+python ./benchmark/get_benchmark_report.py
+```
+
+执行脚本之后得出速度报告,可见使用 lmdeploy 的 Turbomind 可以明显提速,4bit 量化后的模型推理速度比原始推理快 5 倍。
+
+```bash
++---------------------------------+------------------------+-----------------+
+| Model | Toolkit | Speed (words/s) |
++---------------------------------+------------------------+-----------------+
+| streamer-sales-lelemiao-7b | transformer | 60.9959 |
+| streamer-sales-lelemiao-7b | LMDeploy (Turbomind) | 147.9898 |
+| streamer-sales-lelemiao-7b-4bit | LMDeploy (Turbomind) | 306.6347 |
++---------------------------------+------------------------+-----------------+

+## TODO
+
+- [x] 生成多个产品数据集
+- [x] 根据产品生成话术,每个都是5个往来的对话
+- [ ] 每个话术分为3个角色,
+ - [x] 乐乐喵——可爱萝莉,
+ - [ ] 强哥——专业性极强的总裁
+ - [ ] 有文化底蕴的书生
+- [x] 模型推理加速
+- [ ] 接入 RAG 解读产品文档
+- [ ] 后续接入 Agent,支持网上搜索对比同类
+- [ ] 数字人 + 语音
+- [ ] 根据用户的反馈和行为,实时调整解说策略,并推荐产品
+- [ ] 多用户提问时候,建立 good quection 和 bad question 列表防止过度回复?
+
+## 后记
+
+本项目属于个人的一个学习项目,还有很多不足的地方,例如本模型在数据集方面的还没做很精细的调优,还有时候标点符号会错误。
+
+欢迎大家一起讨论,如果大家有数据集,可以在 issue 留言讨论。

+# Modified from transformers.model.llama.configuration_llama.LlamaConfig
+class InternLM2Config(PretrainedConfig):
+ r"""
+ This is the configuration class to store the configuration of a [`InternLM2Model`]. It is used to instantiate
+ an InternLM2 model according to the specified arguments, defining the model architecture. Instantiating a
+ configuration with the defaults will yield a similar configuration to that of the InternLM2-7B.
+
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+ documentation from [`PretrainedConfig`] for more information.
+
+
+ Args:
+ vocab_size (`int`, *optional*, defaults to 32000):
+ Vocabulary size of the InternLM2 model. Defines the number of different tokens that can be represented by the
+ `inputs_ids` passed when calling [`InternLM2Model`]
+ hidden_size (`int`, *optional*, defaults to 4096):
+ Dimension of the hidden representations.
+ intermediate_size (`int`, *optional*, defaults to 11008):
+ Dimension of the MLP representations.
+ num_hidden_layers (`int`, *optional*, defaults to 32):
+ Number of hidden layers in the Transformer encoder.
+ num_attention_heads (`int`, *optional*, defaults to 32):
+ Number of attention heads for each attention layer in the Transformer encoder.
+ num_key_value_heads (`int`, *optional*):
+ This is the number of key_value heads that should be used to implement Grouped Query Attention. If
+ `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
+ `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
+ converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
+ by meanpooling all the original heads within that group. For more details checkout [this
+ paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
+ `num_attention_heads`.
+ hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
+ The non-linear activation function (function or string) in the decoder.
+ max_position_embeddings (`int`, *optional*, defaults to 2048):
+ The maximum sequence length that this model might ever be used with. Typically set this to something large
+ just in case (e.g., 512 or 1024 or 2048).
+ initializer_range (`float`, *optional*, defaults to 0.02):
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+ rms_norm_eps (`float`, *optional*, defaults to 1e-12):
+ The epsilon used by the rms normalization layers.
+ use_cache (`bool`, *optional*, defaults to `True`):
+ Whether or not the model should return the last key/values attentions (not used by all models). Only
+ relevant if `config.is_decoder=True`.
+ tie_word_embeddings(`bool`, *optional*, defaults to `False`):
+ Whether to tie weight embeddings
