# Llama3.1-8B pipeline

<!-- Provide a quick summary of what the model is/does. -->
该模型以Llama-3.1-8B为base model,首先经过SFT进行了指令遵循的调整，为保证与人类道德准则对齐，首先使用了DPO进行对齐训练，在DPO的基础之上又使用了PPO进一步进行对齐规范。<br/>
从实际评估结果上观察，其具有逻辑推理，代码以及安全回复人类指令的能力。


## Training Details and Data
* **SFT dataset**:  xiaodongguaAIGC/alpaca_en_zh_ruozhiba
* **Reward model / DPO datset**: PKU-Alignment/PKU-SafeRLHF-30K
* **PPO training**:  reference from SFT + multi-adapter RLHF

## How to use
**1. load base model**

   ```
    from transformers import AutoModelForCausalLM,AutoTokenizer
    base_model = AutoModelForCausalLM.from_pretrained(
        model_base_name, device_map='auto', torch_dtype=torch.bfloat16, trust_remote_code=True, # llama3.1-8B as base model
    )
   ```
**2. load adapter from this hub**
   ```
    model = PeftModel.from_pretrained(
        base_model,
        model_adapter_name,  # zhengComing/llama3.1-8B-lora
        device_map='auto',
        trust_remote_code=True,
    )
  ```
**3. merge adapter**
  ```
   model = model.merge_and_unload()
  ```
**4. Inference**

  ###Question: 为啥长寿的碰巧都是老年人？
  ###Answer: 由于长寿的定义是指一个人活到很高的年龄，这意味着他们已经经历了很多年。随着年龄的增长，人体的免疫系统会逐渐衰退，身体的各种器官和组织也会逐渐老化。
  然而，随着年龄的增长，人体也会逐渐适应这种变化，学会如何更好地保护自己，避免疾病和伤害。因此，长寿的人往往会更善于保护自己，避免各种危险，保持健康的生活方式。

###Question: Please give me a C++ code about quick sort.
###Answer: 1. Here is a simple implementation of the quick sort algorithm in C++:

//c++
#include <iostream>
#include <vector>

void quickSort(std::vector<int>& arr, int left, int right) {
    if (left >= right) {
        return;
    }

    int pivot = arr[(left + right) / 2];
    int i = left, j = right;

    while (i <= j) {
        while (arr[i] < pivot) {
            i++;
        }
        while (arr[j] > pivot) {
            j--;
        }
        if (i <= j) {
            std::swap(arr[i], arr[j]);
            i++;
            j--;
        }
    }

    quickSort(arr, left, j);
    quickSort(arr, i, right);
}
```
