I can't reproduce this behavior.

Would you be able to provide a full example that replicates this issue?

from flask-apscheduler.

Here is useful link about this topic:
https://stackoverflow.com/questions/9449101/how-to-stop-flask-from-initialising-twice-in-debug-mode

The simplest thing to do here would be to add use_reloader=False to your call to app.run - that is: app.run(debug=True, use_reloader=False)

Alternatively, you can check for the value of WERKZEUG_RUN_MAIN in the environment:

if os.environ.get("WERKZEUG_RUN_MAIN") == "true":
    # The reloader has already run - do what you want to do here

However, the condition is a bit more convoluted when you want the behavior to happen any time except in the loading process:

if not app.debug or os.environ.get("WERKZEUG_RUN_MAIN") == "true":
    # The app is not in debug mode or we are in the reloaded process
