QtPy Interface and Plotly Dash server

[Aetaugan]

Hi everyone,

I'm currently blocked in a strange situation. I'm using QtPy interface to run an instance class containing a Dash App server. The problem is when I start app.run_server(debug=True) the interface is loading again, stopping at the same time the Dash server and crashing the whole application.

#Function run() in Visualise class
def run(self):
      
      self.dataTreatment(app) #Parse Data for Dash
      self.graphsDash(app) #Create Dash components

print("----------------------------------------------------- 3 ---------------------------------------------")
      app.run_server(debug=True) #Start Dash server
print("----------------------------------------------------- 4 ---------------------------------------------")

#Function called from UI mainwindow class
visualise_instance = visualize.Visualise(args)
print("----------------------------------------------------- 1 ---------------------------------------------")
visualise_instance.run()
print("----------------------------------------------------- 2 ---------------------------------------------")

There is no call of UImainwindow class in visualize file, the file is not even imported. Actually, the process doesn't come back to the interface class.

I tried to run the class using threading and QThread manipulation but it always does the same thing.

Do you have any ideas?

Thanks

So apparently, this is due to the Dash debug mode. I don't know why, however.

Change this line

app.run_server(debug = True)

to

app.run_server()
