#lstm_model = make_lstm_model()
min_max_scaler = preprocessing.MinMaxScaler()
train = np.array(train).reshape(-1,1)

train_scaled = min_max_scaler.fit_transform(test_data)

train_X,train_Y = [],[]
for i in range(0 , len(train_scaled) - window_size):
train_X.append(train_scaled[i:i+window_size])
train_Y.append(train_scaled[i+window_size])

The parameter "test_data" can't be found, so I think it should be "residuals". And about "train = np.array(train).reshape(-1,1)", I don't know the meaning of the parameter "train" , it also should be "residuals".
