有没有佬知道、streamlit run webui.py的时候出现TypeError: ‘NoneType‘ object is not iterable咋解决哇_collecting usage statistics. to deactivate, set br

在阿里云服务器PAI上运行的，基于chatglm3-6b的langchain-chatglm具体错误如下：

#  streamlit run webui.py --server.address 127.0.0.1

Collecting usage statistics. To deactivate, set browser.gatherUsageStats to False.

  You can now view your Streamlit app in your browser.

尝试了github上的方法：

1、改python 运行

2、重装httpx: pip install httpx==0.25.0

都失败了。

二编#################

如果python startup.py -a报错长这样，显示驱动版本过旧，阿里云上部署的A10的云服务器就ok咯，本地化上部署可能是torch gpu版本不匹配,查询cpu型号，重新在pytorch官网上 pip install 对应版本可能就会成功（云服务器不能成功）。
