如何在 AWS EC2 上将 Tensorboard 扩展安装到 Jupyter Lab？

Question

我想将 Temsorboard 安装到 AWS EC2 上的 Jupyter 实验室，但它不起作用。 我有与此post 类似的问题。

出于安全考虑，我不想像某些人建议的那样打开防火墙的问题。所以这个答案并不能解决我的情况。而且我不明白为什么它不能这样做，因为我可以使用 anaconda 下载、安装、删除、更新任何软件包，总体而言，防火墙似乎不会对其他任何地方产生负面影响。

环境

• EC2 环境
• Ubuntu 18.04
• SageMaker 实例
• Anaconda 环境

我经常遇到这个问题，即没有安装扩展程序并且可以从扩展程序中运行。例如：在 GUI 中，我搜索了 tensorboard click to install than

Build Recommended
JupyterLab build is suggested:
jupyterlab_tensorboard needs to be included in build

点击BUILD

鉴于此消息：

error ws@7.2.1: The engine "node" is incompatible with this module. Expected version ">=8.3.0". Got "6.13.1"

还有这个：

[LabBuildApp] Node v6.13.1

看起来您正在使用一个过时的 node.js 版本。如果您担心安全性，您应该升级到受支持的 Node.js 版本。 Node 的当前 LTS 版本是 14.17.0（所以你落后了四个 LTS 版本 - 我会害怕使用这样的设置），最新版本是 16.3。我建议升级到节点 12（不太理想）或节点 14（最佳）。

升级 Node.js 时，您很可能还需要更新 JupyterLab，无论如何我都会在您运行时推荐：

[LabBuildApp] JupyterLab 1.2.6

而当前的 JupyterLab 版本是 3.0.16（3.1 即将发布）；我强烈建议至少升级到最新的 2.x 版本（或直接升级到 3.x 系列）；自 1.2.6 版本以来有许多安全修复。

还请注意，从 JupyterLab 3.0 开始，可以安装许多扩展，而根本不需要 Node.js。我现在知道 tensorboard 扩展是否属于这种情况 - 最好与作者核实一下。
