Greetings, ever since I upgraded to Dash 1.0.0, I haven’t been able to get a single application working without an inexplicable SYstemExit occurring. For example, if I tried running a script using the code given in Part Two of the Dash tutorial, I would still have that issue. I’ve reproduced the cod…

Hm… could you try ‘app.run_server(debug=False)’?

Thank you for getting back to me! I figured out the problem, however. This only happened to me when I ran scripts in Spyder’s IPython console. When I ran scripts from command prompt, everything worked again. This is with the latest version of Spyder (v3.3.5).

I tried putting everything in a jupyter notebook ipynb file, putting the code in a .py file and running it in an ipynb file noteboo…

try ‘app.run_server(debug=False)’, the built in reloader doesn’t work when you run this in jupyter kernels.

I have the same problem. The problem only occurs when I set debug=True. No problem if debug=False. I am running the app in Spyder IPython console as well. For this reason I have not been able to set the debug to True to this day.

Cannot run even a simple application after upgrading to Dash 1.0.0
