有谁知道在使用 Google Colab 时如何访问 H2O Flow？

我的代码如下：

!pip install H2O

import h2o
h2o.init(bind_to_localhost=False, log_dir="./")
from google.colab.output import eval_js
print(eval_js("google.colab.kernel.proxyPort(54321)"))

此代码显示以下输出：

并单击https://0258qgrdz6tx-496ff2e9c6d22116-54321-colab.googleusercontent.com/会返回 HTTP 500 错误，并显示“未实现”消息而不是 H2O 流（Web UI）页面。

似乎消息是由Persist类返回的。

您可以使用 localtunnel 公开 H2O.ai 运行的端口：

安装本地隧道：

!npm install -g localtunnel

启动本地隧道：

!lt --port 54321

然后您可以导航到它返回的 url 并访问 H2O.ai 笔记本。
