AttributeError: 'Simple_Imputer' object has no attribute 'fill_value_categorical'' in PyCaret

I am using PyCaret and get an error.

AttributeError: 'Simple_Imputer' object has no attribute 'fill_value_categorical'

Trying to create a basic instance.

!pip install pycaret==1.0

from pycaret.regression import *
exp_reg = setup(data=df, target='Survived', session_id=2)

i reinstaled pycraret (!pip install pycaret) and it worked; no clue what happened.
