Description

Parameter presort in sklearn.ensemble.GradientBoostingClassifier has been deprecated since sklearn v0.22, which may cause trouble when running the primitive 'sklearn.ensemble.GradientBoostingClassifier' with MLPrimitive==0.3.0.

This problem can be solved by restricting the dependency scikit-learn>=0.21,<0.22 in Cardea.

What I Did

When running benchmarking with python cardea/benchmark/benchmark_cli.py, it raised

Exception caught building MLBlock sklearn.ensemble.GradientBoostingClassifier
