I have also encountered the same issue. Didn't solve. Who can help us?

I expect this error is caused by using a more recent version of scikit-learn than 1.5.2 because version 1.6+ uses validate_data rather than _validate_data (with an underscore prefix). Try installing version 1.5.2 until Trevor releases the next version which will probably be compatible with the latest dependencies.
