jupyter笔记本ipython小部件显示为文本

Question

一个同事（和我自己）正在尝试编写一些python脚本来进行一些通用计算，而其他同事也需要使用这些脚本。为了使这些脚本易于使用，我们使用ipywidgets创建了一个简单的GUI。但是，这些小部件不是很稳定，有时它们可​​以显示并正常工作，但有时它们不显示而是将对象显示为文本：

ToggleButton(value=False, description='Design choice 1', icon='che…
ToggleButton(value=False, description='Design choice 2', icon='check', tooltip='Description')
Button(description='Continue to assign input values', icon='check', style=ButtonStyle(), tooltip='Click me' 

我们要实现的目标是建立一个简单的系统，以便我们的同事可以轻松地使用我们的脚本。为此，我们将要求他们安装miniconda，然后运行一个批处理文件以安装所有必需的软件/软件包（实质上是使用conda从文件中安装软件包列表）。但是，当我使用当前设置执行此操作时，它并不总是能正常工作。

在我的笔记本扩展中：

您知道我如何获得稳定的设置以使这些扩展正常工作吗？
