class evalml.pipelines.CatBoostMulticlassClassificationPipeline(parameters, random_state=0)

CatBoost Pipeline for multiclass classification. CatBoost is an open-source library and natively supports categorical features.

For more information, check out https://catboost.ai/ Note: impute_strategy must support both string and numeric data
