Server timeout when opening dash with a long process

Dash Python
1

I am working on a dashboard with Dash. The problem is that the server has a default timeout of 60 seconds when I start the Dash, but the timeout is not there for callbacks. So, when I calculate everything during Dash initialization, I get the timeout.

When I try to run it like this,

X_train, y_train, X_test, y_test = titanic_survive()
model = LogisticRegression().fit(X_train, y_train)
explainer = ClassifierExplainer(model, X_test, y_test)
db = ExplainerDashboard(explainer, shap_interaction=False)
db.explainer_layout.register_callbacks(app)   
app.layout = db.explainer_layout.layout()

I get the timeout on start up. I thought, I might load the Dash with a landing page and put the computations into a button click.

app.layout = html.Div([
    html.Button('Submit', id='submit', n_clicks=0),
    html.Div(id='container-button-basic', children='')
])

X_train, y_train, X_test, y_test = titanic_survive()
model = LogisticRegression().fit(X_train, y_train)
explainer = ClassifierExplainer(model, X_test, y_test)

@app.callback(
    Output('container-button-basic', 'children'),
    Input('submit', 'n_clicks'),
)
def update_output(n_clicks):

    if n_clicks == 1:
        db = ExplainerDashboard(explainer, shap_interaction=False) 
        db.explainer_layout.register_callbacks(app)     
        return db.explainer_layout.layout()

However, when I do it like this, the “db.explainer_layout.register_callbacks(app)” doesn’t seem to work. I get the dashboard but it looks the register callback doesn’t work and all the plots are empty.

The ExplainerDashboard is a Python package explainerdashboard — explainerdashboard 0.2 documentation

I don’t have access to the server since I run this through Dataiku. So, I am not sure how to proceed.
