It has been resolved! Thank you! Can I know how you solved it? I'm also getting this error now.

Hi,

scikit-learn is a dependency of the package and is installed when you install pyts. sklearn.preprocessing.PowerTransformer has been added in scikit-learn==0.20 and pyts requires scikit-learn>=0.22, so it should be available.

Can you please give the versions of the these packages?

import pyts; print("pyts", pyts.__version__)
import sklearn; print("scikit-learn", sklearn.__version__)
