In JupyterLab from KubeFlow,When i open Tensorboard,it always in initializing

The most likely cause for this problem is that the backend of jupyterlab-tensorboard-pro has not been successfully installed
Or didn't find it in the KubeFlow environment. (Actually I didn't use it in KubeFlow before)

Some ideas:

  • try import jupyterlab_tensorboard_pro in jupyterlab terminal to check if it is found
  • use --debug to start jupyter, and search jupyterlab_tensorboard_pro in stdout to find some error message

I'll see if I can find a kubeflow environment to try this weekend

Can u speak Chinese?
I can import jupyterlab_tensorboard_pro with no error,but i can't open jupyterlab tensorboard pro,and i think it is difficult for me to start jupyter again in the kubeflow.

如果你能看懂中文的话，我是在[](https://github.com/tencentmusic/cube-studio/) 这个平台下使用的tensorboard-pro,具体复现过程：
部署完这个平台后，在“在线开发”、“代码开发”的notebook模块下，新建了一个notebook,镜像选取的是“notebook:jupyter-ubuntu-cpu-base”，然后安装咱们的tensorboard pro，之后能看到tensorboard pro模块，但打不开

i see the log in Dashboard:

从以上信息来看，确实是后端部分没有安装成功。

实际上，这类 jupyter 插件后端安装成功后，一般会有两个内容：

  1. 配置文件，在 etc/jupyter/jupyter_server_config.d/jupyterlab_tensorboard_pro.json，jupyter 后端会自动读取 etc/jupyter 这里的配置文件，来尝试加载插件，里面的内容：
{
  "ServerApp": {
    "jpserver_extensions": {
      "jupyterlab_tensorboard_pro": true
    }
  }
}
  1. python 包，路径在 lib/python3.8/site-packages/jupyterlab_tensorboard_pro

如果是我们自己 python 环境安装的话，这样就够了。

从你这里的情况来看，可能是:

  1. 配置文件没有正确写入
  2. 不过更可能是你在 jupyterlab 启动之后安装的插件，这个时候其实已经晚了，看看能不能持久化之后重启一下。

我看了下这个平台，目前我这里部署的话可能会面临一些问题，我之后再关注试试看，不过你可以先看看是不是我上面猜想的原因

明白了，不过还好这个平台上已经有镜像包含您的这个插件了，然后也可以正常使用了，但是我本地环境测试安装又出现这个问题了，我估计是在jupyterlab启动后安装造成的，回头我再试试看，谢谢解答！

这个问题的平台我后续继续关注一下，然后现在既然正常使用了这个 issue 我就先关闭了
