[BUG] Custom eval_metric compatibility issues

Bug Report Checklist

  • I provided code that demonstrates a minimal reproducible example.
  • I confirmed bug exists on the latest mainline of AutoGluon via source install.
  • I confirmed bug exists on the latest stable version of AutoGluon.

Describe the bug I have given a custom eval_metric to the predictor, both by creating a custom metric with make_scorer and by providing the predictor with an uninstantiated root_mean_squared_log_error, but neither of these worked. The predictor seems to expect the scoring function to have a needs_proba attribute, which the latest version of sklearn does not have. This attribute has been deprecated since version 1.4 and is replaced by response_method. As far as I understand, version 1.2 should support version 1.5.2 of sklearn, so I see this as a bug.

Expected behavior I expect no errors.

To Reproduce

Dataset: https://www.kaggle.com/competitions/playground-series-s4e12

Code:

python
from sklearn.metrics import root_mean_squared_log_error
from autogluon.tabular import TabularPredictor
import pandas as pd

train = pd.read_csv('/kaggle/input/playground-series-s4e12/train.csv', index_col='id')

predictor = TabularPredictor(
    problem_type='regression',
    eval_metric=root_mean_squared_log_error,
    label="Premium Amount",
    verbosity=2
)

predictor.fit(
    train_data=train,
    time_limit=3600,
    presets='best_quality'
)
