安装插件后，一直显示initializing

我安装了插件之后一直在initializing 我的环境是 python:3.7 TensorFlow-gpu=2.3.1 IPython : 8.13.2 ipykernel : 6.23.0 ipywidgets : 8.0.6 jupyter_client : 8.2.0 jupyter_core : 5.3.0 jupyter_server : 2.5.0 jupyterlab : 3.6.3 nbclient : 0.7.4 nbconvert : 7.4.0 nbformat : 5.8.0 notebook : 6.5.4 qtconsole : 5.4.3 traitlets : 5.9.0

安装插件之后显示了这个错误：

    If you are experiencing the build failure after installing an extension (or trying to include previously installed extension after updating JupyterLab) please check the extension repository for new installation instructions as many extensions migrated to the prebuilt extensions system which no longer requires rebuilding JupyterLab (but uses a different installation procedure, typically involving a package manager such as 'pip' or 'conda').

    If you specifically intended to install a source extension, please run 'jupyter lab build' on the server for full output.

运行了jupyter lab build之后又出现了这个错误：

[LabBuildApp] JupyterLab 3.6.3 [LabBuildApp] Building in /opt/conda/share/jupyter/lab [LabBuildApp] Building jupyterlab assets (production, minimized) Build failed. Troubleshooting: If the build failed due to an out-of-memory error, you may be able to fix it by disabling the dev_build and/or minimize options.

If you are building via the jupyter lab build command, you can disable these options like so:

jupyter lab build --dev-build=False --minimize=False

You can also disable these options for all JupyterLab builds by adding these lines to a Jupyter config file named jupyter_config.py:

c.LabBuildApp.minimize = False c.LabBuildApp.dev_build = False

If you don't already have a jupyter_config.py file, you can create one by adding a blank file of that name to any of the Jupyter config directories. The config directories can be listed by running:

jupyter --paths

Explanation:

• dev-build: This option controls whether a dev or a more streamlined production build is used. This option will default to False (i.e., the production build) for most users. However, if you have any labextensions installed from local files, this option will instead default to True. Explicitly setting dev-build to False will ensure that the production build is used in all circumstances.

• minimize: This option controls whether your JS bundle is minified during the Webpack build, which helps to improve JupyterLab's overall performance. However, the minifier plugin used by Webpack is very memory intensive, so turning it off may help the build finish successfully in low-memory environments.

An error occurred. RuntimeError: JupyterLab failed to build See the log file for details: /tmp/jupyterlab-debug-tkis9x15.log

这个插件使用了 scss，根据 jupyterlab 的 issue, 不支持 jupyter lab build，直接安装应该是不需要 jupyter lab build 这个过程的。

一直 initializing 一般是 tensorboard 后端启动的过程报错了，可以开启 debug 日志看看？

yarn install 报错
