[BUG] LightGBMRegressor Verbosity = 1, isProvideTrainingMetric= True do nothing

[sohaibsyed21]

SynapseML version

1.0.4

System information

• Language version (e.g. python 3.8, scala 2.12): Python 3.9
• Spark Version (e.g. 3.2.3): 3.5.1
• Spark Platform (e.g. Synapse, Databricks): Amazon EMR version 7.2.0

Describe the problem

Working on a feature selection function using LightGBMRegressor() and according to documentation there are parameters named 'verbosity' and 'isProvideTrainingMetric' that I would assume print out information for training and evaluation metrics as the model trains. However, this is not the case. There are no errors raised, simply missing output or logs that I assume should be there. An additional detail is that I am not setting up an iteration loop; this is a single pass fit.

Code to reproduce issue

    # Add a 'validation' column
    train_df_withVal = train_df.withColumn(
        'validation', 
        F.when(rand() < val_frac, 1).otherwise(0)
    )

    pandas_df_withVal = train_df_withVal.toPandas()
    pandas_df_withVal.to_excel(f"{model_output_archive_directory}/traindf_withVal.xlsx", index=False)


    model = LightGBMRegressor(**params, featuresCol='features',\
        labelCol=target_feature_name, seed=random_seed, featuresShapCol='shap_values',validationIndicatorCol='validation',verbosity=1,isProvideTrainingMetric= True).fit(train_df_withVal)

    model.saveNativeModel('/mnt/model')

I think so many people asked the same question, how to see the loss curve. I believe the verbosity does not relate to this. (although I also want that function
