Redundant parameter error with HomoSecureBoost

[Rono-BC]

Hi Everyone,

I'm using FATE v1.5.3

I'm getting an error when defining the parameters for a HomoSecureBoost model:

retcode": 100, "retmsg": "Component homo_sb_0, module HomoSecureboost, has redundant parameter max_depth"

I'm defining the parameters as follows:

 homo_lr_params = {
        'num_trees': 100,
        'task_type': 'classification',
        'learning_rate': 0.1,
        'max_depth': 5
    }

In the docs I see the DecisionTreeParam class which allows setting max_depth but I don't see where it should be passed?

Thanks in advance!

I figured out the answer. In case anyone else is wondering the same, max_depth is from the DecisionTreeParam class. Its parameters can bet set under tree_param as part of the params passed for a HomoSecureBoost model as below:

homo_sb_params = {
            'num_trees': 100,
            'task_type': 'classification',
            'learning_rate': 0.1,
            'tree_param': {
                'max_depth': 5,
            }
        }
