我想使用jupyterlab-nvdashboard从 JupyterLab 监控 GPU 性能。虽然 github 中没有提到它，但我发现 conda-forge 频道中也提供了该扩展，我从那里安装了它。
conda install -c conda-forge jupyterlab-nvdashboard
安装没有错误，最后一个环境列表条目显示 jupyterlab-nvdashboard-0.6.0 与依赖项 pynvml-11.0.0 一起安装：
2021-10-21 12:15:21 (rev 8)
+jupyterlab-nvdashboard-0.6.0 (conda-forge/noarch)
+pynvml-11.0.0 (conda-forge/noarch)
我正在运行最新版本的 jupyter-lab >= 3.0
$ jupyter --version
Selected Jupyter core packages...
IPython : 7.28.0

这是我在尝试安装 labextension 时遇到的错误。
$ jupyter labextension install jupyterlab-nvdashboard
An error occurred.
ValueError: The extension "jupyterlab-nvdashboard" does not yet support the current version of JupyterLab.
