Obtain the graph of the autocorrelation function in ARIMA models

Question

I am implementing an ARIMA model in Python for forecasting US GDP.

I am interested in obtaining the graph for the autocorrelation function. I obtained the values for ACF but I can not see the graph even though I have written

>>>import statsmodels.api as sm
>>>sm.graphics.tsa.plot_acf

Enter and nothing appears. Just this

<function plot_acf at 0x0000000014E44358>

Thank you very much!

Answer 1

It looks like you forgot the parenthesis at the end:

import statsmodels.api as sm
sm.graphics.tsa.plot_acf()
