Question

我正在尝试使用Dash框架开发应用程序，但是在运行代码时，出现“回溯”错误。

我正在通过IDLE学习它，但是我已经尝试用Jupyter编写代码。我得到了不同的错误，但是似乎没有一个起作用。

import dash
import dash_core_components as dcc
import dash_html_components as html
app = dash.Dash()
app.layout = html.Div(children=[
    html.H1(children='Dash Tutorials'),
    dcc.Graph()
])
if __name__ == '__main__':
    app.run_server(debug=True)

这是我从IDLE获得的结果：

这是我从Jupyter Notebook得到的结果：
