Answer 1

感谢您发现问题并发布了解决方法。 wit-widget 1.7.1-alpha.3并不打算作为wit-widget的“最新”软件包公开，因为它有问题。 wit-widget最新标签已恢复为1.7.0。

Answer 2

问题：

机智小部件1.7.1alpha3

解决方法：

SSH进入实例并禁用扩展名：

jupyter labextension list
Config option `kernel_spec_manager_class` not recognized by `ListLabExtensionsApp`.
JupyterLab v1.2.16
Known labextensions:
   app dir: /opt/conda/share/jupyter/lab
        @jupyter-widgets/jupyterlab-manager v1.1.0  enabled  OK
        @jupyterlab/celltags v0.2.0  enabled  OK
        @jupyterlab/git v0.11.0  enabled  OK
        jupyterlab-plotly v1.5.1  enabled  OK
        jupyterlab_gcpscheduler v1.0.4  enabled  OK
        nbdime-jupyterlab v1.0.0  enabled  OK
        plotlywidget v1.5.1  enabled  OK
        wit-widget v1.7.1-alpha.3 enabled OK

jupyter labextension disable wit-widget 
# Ignore `Config option `kernel_spec_manager_class` not recognized by `DisableLabExtensionsApp` message.

jupyter labextension list (Verify wit-widget is disabled)
service jupyterlab restart
