Implementing SARIMAX in Python gives 0%| | 0/256 [00:00<?, ?it/s]

Question

I am trying to implement the following code in Python from this article.

Here is my code snippet.

def optimize_SARIMA(parameters_list, d, D, s, exog):
    results = []
    for param in tqdm_notebook(parameters_list):
        model = SARIMAX(exog, order=(param[0], d, param[1]), seasonal_order=(param[2], D, param[3], s)).fit(disp=-1)
        
    aic = model.aic
    results.append([param, aic])
    result_df = pd.DataFrame(results)
    result_df.columns = ['(p,q)x(P,Q)', 'AIC']
    #Sort in ascending order, lower AIC is better
    result_df = result_df.sort_values(by='AIC', ascending=True).reset_index(drop=True)
    return result_df

p = range(0, 4, 1)
d = 1
q = range(0, 4, 1)
P = range(0, 4, 1)
D = 1
Q = range(0, 4, 1)
s = 4

parameters = product(p, q, P, Q)
parameters_list = list(parameters)
result_df = optimize_SARIMA(parameters_list, 1, 1, 4, yValues)

yValues for me is just a list of integers. It keeps outputting this to the console:

  0%|          | 0/256 [00:00<?, ?it/s]

I cannot figure out why this is.
