流光通过谷歌Colab通过LocalTunnel不再工作

Question

我在Colab上使用LocalTunnel。直到昨天它都一直工作得很好。但从那以后它就停止工作了。我的代码有这样的结构:

! pip install streamlit -q

然后

%%writefile app.py
import streamlit as st
st.write('# test')

最后

!streamlit run /content/app.py & npx localtunnel --port 8501

我现在得到这样的输出:

Traceback (most recent call last):
File "/usr/local/bin/streamlit", line 5, in <module>

当我跟随链接并点击&;continue&;按钮，页面没有加载，我得到:"504网关超时"。

我可以在输出中看到Enum LabelVisibilityOptions上有一个AttributeError。

我用上面非常简单的代码创建了一个新的笔记本，我得到了同样的错误。

你知道它是从哪里来的吗?如何解决这个问题?提前感谢您的输入!

我得到了同样的错误，我通过回到以前的Streamlit版本来解决它，像这样:

pip install streamlit==1.13.0

你可以在1.14.0版本的更改日志中看到一些关于Enum类的更改。
