使用Google Colab时如何访问H2O流量

有人知道在使用Google Colab时如何访问H2O流量吗?

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:

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