I am trying to create a revenue prediction model:
print(type(data))
<class 'pandas.core.series.Series'>
train, test = temporal_train_test_split(data, test_size = 217)
fh = np.arange(len(test)) + 1
ari = AutoARIMA()
ari.fit(train)
pred = ari.predict(fh)
I keep getting this error message
None of [Int64Index([ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, ...
207, 208, 209, 210, 211, 212, 213, 214, 215, 216],
dtype='int64', length=217)] are in the [index]
Why is this happening and what is meant by index here?
