Hi!

Try:

pip install prophet

and try again. I don't include prophet as a required library because it has a lot of known installation issues.

Hi Michael, could you please help with a further error with prophet? My data has 53 observations. After taking a first order differencing, now there are 52 observations. After I feed the data into the models by running the code below. Everything is good except an error with prophet:

Code:

f.set_validation_length(6)
models = ('mlr','knn','svr','xgboost','gbt','elasticnet','mlp', 'arima','prophet')
for m in models:
f.set_estimator(m)
f.tune() # by default, will pull grids from Grids.py
f.auto_forecast()

Error:

556 if floor is not None:
557     X["floor"] = floor

--> 558 X["y"] = self.y.to_list()
...
574 "does not match length of index "
575 f"({len(index)})"
576 )

ValueError: Length of values (52) does not match length of index (53)

Do you know what would possibly be the reason for the error?

Thank you so much!

This looks like a bug. Give me second to look into it.

I was able to reproduce the error and found the source of the issue. In the next update, this will be fixed. I could probably commit a new version today or tomorrow.
