# InternLM-Chat 智能体

[English](README.md) | 简体中文

## 简介

InternLM2.5-Chat 在代码解释和通用工具调用方面的能力得到进一步提升。基于更强和更具有泛化性的指令理解、工具筛选与结果反思等能力，新版模型可以更可靠地支持复杂智能体的搭建，支持对工具进行有效的多轮调用，完成较复杂的任务。在配合代码解释器（code-interpreter）的条件下，InternLM2.5-Chat 在 MATH 上可以达到和 GPT-4 相仿的水平。基于在数理和工具方面强大的基础能力，InternLM2.5-Chat 提供了实用的数据分析能力。

以下是 InternLM2.5-Chat 在数学代码解释器上的结果。

|        模型         | 是否集成工具 | MATH |
| :-----------------: | :----------: | :--: |
|  InternLM2-Chat-7B  |      w/      | 45.1 |
| InternLM2-Chat-20B  |      w/      | 51.2 |
| InternLM2.5-7B-Chat |      w/      | 63.0 |
| gpt-4-0125-preview  |     w/o      | 64.2 |

## 体验

我们提供了使用 [Lagent](lagent_zh-CN.md) 来基于 InternLM2.5-Chat 构建智能体调用代码解释器的例子。首先安装额外依赖：

```bash
pip install -r requirements.txt
```

运行以下脚本在 MATH 测试集上进行推理和评估：

```bash
python streaming_inference.py \
  --backend=lmdeploy \  # For HuggingFace models: hf
  --model_path=internlm/internlm2_5-7b-chat \
  --tp=1 \
  --temperature=1.0 \
  --top_k=1 \
  --output_path=math_lmdeploy.jsonl \
  --do_eval
```

`output_path` 是一个存储推理结果的 jsonl 格式文件，每行形如：

````json

                }
            },

如果已经准备好了该文件，可直接跳过推理阶段进行评估：

```bash
python streaming_inference.py \
  --output_path=math_lmdeploy.jsonl \
  --no-do_infer \
  --do_eval
```
