我正在尝试学习python中的dash应用程序包,我从基本教程开始,如下所示,
import dash
import dash_core_components as dcc
import dash_html_components as html
app = dash.Dash()
app.layout = html.Div(' Dash Tutorials')
if __name__ == '__main__':
app.run_server(debug=True)
但是我收到以下错误,
* Restarting with stat
An exception has occurred, use %tb to see the full traceback.
SystemExit: 1
当我输入%tb时,显示以下内容,
---------------------------------------------------------------------------
SystemExit Traceback (most recent call last)

264 else:
--> 265 sys.exit(reloader.restart_with_reloader())
266 except KeyboardInterrupt:
267 pass
SystemExit: 1
我已经尝试了几种方法来解决这个问题。但我找不到解决方案。任何人都可以帮助我解决这个问题吗?
谢谢
在禁用调试模式的情况下运行它:
if __name__ == '__main__':
app.run_server(debug=False)
