AttributeError: module 'skgrf.grf' has no attribute 'regression_train'

[Sten-Ostendorf]

I get this error when trying to use GRFForestRegressor to fit, if I try a local linear regressor i get the same error but for 'll_regression_train'. I've tried checking if all packages are the right version and follow the guidlines from all examples I can find, but it doesn't seem to work..
