硬件要求（模型推理）：
INT4 ： RTX3090*1，显存24GB，内存32GB，系统盘200GB
如果你没有 GPU 硬件的话，也可以在 CPU 上进行推理，但是推理速度会更慢。
模型微调硬件要求更高。一般不建议个人用户环境使用
环境准备
模型准备
git clone https://hf-mirror.com/THUDM/chatglm3-6b
手动下载以下几个模型（体验时几个模型不一定需全下载）
下载地址：https://hf-mirror.com/THUDM
THUDM/chatglm3-6b
下载源码
git clone https://github.com/THUDM/ChatGLM3.git;
cd ChatGLM3
创建conda环境
conda create -n chatglm3 python=3.10 -y
source activate chatglm3
修改本国内源
pip config set global.index-url http://mirrors.aliyun.com/pypi/simple
pip config set install.trusted-host mirrors.aliyun.com
安装依赖库
pip install -r requirements.txt
运行
streamlim方式启动
streamlim run composite_demo/main.py
第一次运行时可能存在部分依赖包没有完整的下载的情况，根据错误提示，分别安装缺失的依赖库：
上面的错误主要是huggingface_hub 的版本问题。指定版本huggingface_hub==0.21.4， 再次执行即可。

启动时模型加载可以离线下载，也可以自动下载，（根据自身网络情况准备）
- 自动联网下载，启动即可自动完成下载，不需要作任何更改
- 离线下载
如果事先已经准备好模型，需要更改模型家在路径，修改文件composite_demo/client.py，把地址改为自己模型的绝对路径即可：
MODEL_PATH = os.environ.get(‘MODEL_PATH’, ‘THUDM/chatglm3-6b’)
更改为：
MODEL_PATH = os.environ.get(‘MODEL_PATH’, ‘/u01/workspace/chatglm3/models/chatglm3-6b’),
/u01/workspace/chatglm3/models/chatglm3-6b请据实修改
MODEL_PATH = os.environ.get('MODEL_PATH', '/u01/workspace/chatglm3/models/chatglm3-6b')
PT_PATH = os.environ.get('PT_PATH', None)
PRE_SEQ_LEN = int(os.environ.get("PRE_SEQ_LEN", 128))
TOKENIZER_PATH = os.environ.get("TOKENIZER_PATH", MODEL_PATH)
成功加载后可以打开界面

部署 API 服务
启动 API 服务，服务的默认端口是 8000：
python openai_api_demo/api_server.py
启动服务端之后，可以通过curl验证
