When I try this:
model = ARIMA(factors[:, i], (1, 1, 1))
forecast = model.fit().predict(np.shape(factors)[0] - 1, np.shape(factors)[0], typ='levels')
All it says is:
Something went wrong. Sorry for the inconvenience. Try using the built-in debugger to analyze your code. If you would like help, send us an email.
There is no error reported. Anyone please?
