Arguments

--input_zarr_path

Path to the input Zarr zip store containing the features and labels. (default value: PARAMETER_VALUE)

--output_model_path

Path for the output joblib file containing the trained LightGBM model. (default value: PARAMETER_VALUE)

--n_estimators

Number of trees in the LightGBM model. (default value: 750)

--max_depth

The maximum depth of the trees. (default value: 18)

--learning_rate

The learning rate. (default value: 0.1)

--num_leaves

Maximum number of leaves. (default value: 31)

--class_weights
