本文介绍采用 [Transformers](#import-from-transformers)、[ModelScope](#import-from-modelscope)、[Web demos](#dialogue)
|
|
|
|
对 InternLM2-Chat 进行推理。
|
|
|
|
|
|
|
|
你还可以进一步了解 InternLM2-Chat 采用的[对话格式](./chat_format_zh-CN.md),以及如何[用 LMDeploy 进行推理或部署服务](./lmdeploy_zh-CN.md),或者尝试用 [OpenAOE](./openaoe.md) 与多个模型对话。

## 通过 Transformers 加载
|
|
|
|
|
|
|
|
通过以下的代码从 Transformers 加载 InternLM 模型 (可修改模型名称替换不同的模型)
|
|
|
|
|
|
|
|
```python
|
|
|
|
>>> from transformers import AutoTokenizer, AutoModelForCausalLM
|
|
|
|
>>> tokenizer = AutoTokenizer.from_pretrained("internlm/internlm2-chat-7b", trust_remote_code=True)
|
|
|
|
>>> model = AutoModelForCausalLM.from_pretrained("internlm/internlm2-chat-7b", trust_remote_code=True).cuda()
|
|
|
|
>>> model = model.eval()
|
|
|
|
>>> response, history = model.chat(tokenizer, "你好", history=[])
|
|
|
|
>>> print(response)
|
|
|
|
你好!有什么我可以帮助你的吗?
|
|
|
|
>>> response, history = model.chat(tokenizer, "请提供三个管理时间的建议。", history=history)
|
|
|
|
>>> print(response)
|
|
|
|
```
|
|
|
|
|
|
|
|
### 通过 ModelScope 加载
|
|
|
|
|
|
|
|
通过以下的代码从 ModelScope 加载 InternLM2-Chat 模型 (可修改模型名称替换不同的模型)
|
|
|
|
|
|
|
|
```python
|
|
|
|
from modelscope import snapshot_download, AutoTokenizer, AutoModelForCausalLM
|
|
|
|
import torch
|
|
|
|
model_dir = snapshot_download('Shanghai_AI_Laboratory/internlm2-chat-7b', revision='v1.0.0')
|
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_dir, device_map="auto", trust_remote_code=True,torch_dtype=torch.float16)
|
|
|
|
model = AutoModelForCausalLM.from_pretrained(model_dir,device_map="auto", trust_remote_code=True,torch_dtype=torch.float16)
|
|
|
|
model = model.eval()
|
|
|
|
response, history = model.chat(tokenizer, "hello", history=[])
|
|
|
|
print(response)
|
|
|
|
response, history = model.chat(tokenizer, "please provide three suggestions about time management", history=history)
|
|
|
|
print(response)
|
|
|
|
```
|
|
|
|
|
|
|
|
## 通过前端网页对话
|
|
|
|
|
|
|
|
可以通过以下代码启动一个前端的界面来与 InternLM2 Chat 7B 模型进行交互
|
|
|
|
|
|
|
|
```bash
|
|
|
|
pip install streamlit==1.24.0
|
|
|
|
pip install transformers==4.30.2
|
|
|
|
streamlit run ./web_demo.py
|
|
|
|
```
