Dash suppress_callback_exceptions not working

问题

Here is how I implement it in my code. I have tried each way individually and using all of them as uncommented lines of code. No matter the combination of methods I use, I still have to manually turn suppress errors once my dashboard loads.

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
app.title = 'TEST'

app.config['suppress_callback_exceptions'] = True
app.config.suppress_callback_exceptions = True

I have also tried (without any luck):

app = dash.Dash(__name__, external_stylesheets=external_stylesheets,
                suppress_callback_exceptions = True)

and

import sys
class HaltCallback(Exception):
    pass

@app.server.errorhandler(HaltCallback)
def handle_error(error):
    print(error, file=sys.stderr)
    return ('', 204)

Are there any other possible ways I can try to suppress the callback exceptions? I'm making a dashboard for my boss, so I'd really like automate the error suppression upon loading it.

回答1:

Figured it out

if __name__ == '__main__':
    app.run_server(debug=False,dev_tools_ui=False,dev_tools_props_check=False)

Needed to just disable dev_tools_ui on the actual webpage
