Same problem here...

Solution for Flask: pass use_reloader=False to app.run hence:

app.run(use_reloader=False)

Cheers 😄

Small additional comment -- I'm not sure if this is something Flask-, or my-project-specific (probably the former), but for line_profiler to work properly, your view function definitions should be in the following form:

@app.route("/")
@profile
def index():

i.e., the @profile decorator should be "within" the @app.route one, not the other way around.

@gregsadetsky Thank you for your reply. The reason for my error is run Flask in the debug mode, as follows: app.run(host='0.0.0.0', port=5000, debug=True) When I remove 'debug=True' the error disappeared.

Not line-profiler related.
