用开源大模型食用指南 self-llm项目的 GLM-4-9B-Chat WebDemo 部署文档部署时遇到如下错误：

经排查报错原因是官方的bug导致，最新的包有问题。
重新安装下transformers的包并重启问题就可以解决
pip install transformers==4.40.2
注意：
1、下载模型的第一行代码导包书写有误，需要自行更改下。源代码如下：
import torch
from modelscope import snapshot_download, AutoModel, AutoTokenizer
import os
model_dir = snapshot_download('ZhipuAI/glm-4-9b-chat', cache_dir='/root/autodl-tmp', revision='master')
2、注意模型的路径，将路径改为绝对路径。
mode_name_or_path = '/root/autodl-tmp/ZhipuAI/glm-4-9b-chat'
