You have two pathway to go about this:

If you are running statsmodels==0.11.0, statsmodels.tsa.filters._utils function was removed from the library.

Alternatively you may use statsmodels.tsa.seasonal.STL, which gives similar functionality. See its documentation: https://www.statsmodels.org/stable/generated/statsmodels.tsa.seasonal.STL.html#statsmodels.tsa.seasonal.STL

Downgrade to pip install statsmodels==0.10.2

Downgrading options doesn't solve the issue, although indeed that's what was suggested in the relevant Github issue: github.com/jrmontag/STLDecompose/issues/17

It's ok to use from statsmodels.tsa.seasonal import STL
