Can't use this to predict.

I'm sorry to bother you, I can't use your package to predict the results. I can use this package to predict arma(4,0)-grach(1,1), but when I bulid arma(4,0)-grach(1,2) there is something wrong, please help me, I'm really in a hurry.

`--------------------------------------------------------------------------- ValueError Traceback (most recent call last)

I use the example code and got the following error: Traceback (most recent call last): File "D:/！paper/第六篇/newtxt/exp/getdata/predict.py", line 25, in model.fit() File "C:\Users\wj\Anaconda3\lib\site-packages\armagarch-1.0.2-py3.6.egg\armagarch\empModel.py", line 161, in fit File "C:\Users\wj\Anaconda3\lib\site-packages\scipy\optimize\slsqp.py", line 208, in fmin_slsqp constraints=cons, *opts) File "C:\Users\wj\Anaconda3\lib\site-packages\scipy\optimize\slsqp.py", line 379, in _minimize_slsqp fx = func(x) File "C:\Users\wj\Anaconda3\lib\site-packages\scipy\optimize\optimize.py", line 293, in function_wrapper return function((wrapper_args + args))
