Croston Forecaster needs extra argument "fitted" [BUG]

[JensvandeZande]

Describe the bug
When trying to fit a Croston Forecaster it returns a TypeError: not enough arguments: expected 4, got 3

To Reproduce

from darts.datasets import AirPassengersDataset
from darts.models import Croston

passengers = AirPassengersDataset()
y = passengers.load()

train = y[:-12]
val = y[-12:]

model = Croston()
model.fit(train)

Expected behavior
A fitted model without errors

System (please complete the following information):

• Python version: [3.19.13]
• darts version [0.20.0]

I just tried and for me it works:

Could you try again in a blank virtual environment?

@JensvandeZande , statsforecasting released a new version with some breaking changes.

Try downgrading the package to see uf it fixes the issue:

pip install --upgrade statsforecast==0.6.0

Indeed, i missed this when carrying out the test above. This issue will be fixed in the new release of Darts: #1106
