AttributeError: 'SimpleImputer' object 在 PyCaret 中没有属性 '_validate_data'

Question

I am using PyCaret and get an error.

AttributeError: 'SimpleImputer' object has no attribute '_validate_data'

Trying to create a basic instance.

# Create a basic PyCaret instance
import pycaret
from pycaret.regression import *
mlb_pycaret = setup(data = pycaret_df, target = 'pts', train_size = 0.8, numeric_features = ['home', 
'first_time_pitcher'], session_id = 123)

All my variables are numeric (I coerced two of them, which are boolean). My target variable is label and this is by default.

I also installed PyCaret , imported its regression, and re-installed scikit learn , imported SimpleImputer as from sklearn.impute import SimpleImputer

My traceback is the following:

Answer 1

The problem here is with the imputation. The default per pycaret documentation is 'simple' but in this case, you need to make that imputation_type='iterative' for it to work.

Answer 2

It's incompatibility of library, install pycaret again with: pip install pycaret pandas shap

Answer 3

Good day all. What helped me is installing pycaret=='2.3.10 ' and scikit-learn='0.23.2' at the same time. These two version are compatible and all works fine. I installed scikit-learn using conda as the older versions are not available through pip, and I installed Pycaret using pip3. I hope this helps all who have struggled to get this working like I did.
