My code is attached below, very simple. I test the download function successfully with a small sample (1MB). However, I need to return a large file about 1 GB, it raise the Memory Error. What should I do ?
dbc.Button('Download', color='primary', id='btn_data',outline=True),
dcc.Download(id="download-image")
@app.callback(
Output("download_data", "data"),
Input("btn_data", "n_clicks"),
prevent_initial_call=True,
)
def func(n_clicks):
return dcc.send_file(
"./download/1218.csv"
)
