python - Plotly-Dash：如何从 Dash WebApp 中删除状态图标？

Question

我正在使用 Dash plotly 为 IPL 构建 Web Dashboard。那里有一个显示网络服务器状态的状态图标。

我怎样才能从网页中删除它？我无法解释太多所以添加下面标记为黄色的图像

Answer 1

只需Debug=False在这里设置就可以了：

app.run_server(debug=False)

我将使用我以前的一篇文章来说明它。您将在下面找到完整的代码片段。

1 - app.run_server(debug=True)

2 - app.run_server(debug=False)

    df['model']=y_reg

    fig = go.Figure()
    fig.add_traces(go.Scatter(x=df['total_bill'], y=df['tip'], mode='markers', name = 'observations'))

    return(fig)

# Run app and display result inline in the notebook
app.enable_dev_tools(dev_tools_hot_reload =True)
app.run_server(mode='inline', port = 8040, dev_tools_ui=True, debug=False,
              dev_tools_hot_reload =True, threaded=True)
