Error when running catboost on valid training and target sets version 1.1.1

[xander-Ito-Low]

def train_model_pandas(self, train_df: pd.DataFrame, valid_df: pd.DataFrame = None):

labels = some function call that extracts labels successfully
# this part works
 training =  train_df.merge(labels, on="common key")

y = training[['target variable']]
Y = pd.get_dummies(y)
X = np.vstack(training['feature_scaled'].fillna(0))

I checked if any of these were null, they weren't and are of the same number of rows (422,8): target shape, (422,23) training shape. Target is pandas dataframe and X is numpy

#now call catboost here
#model training fails

self.__model = CatBoostClassifier(
    iterations = 10000,
    learning_rate=0.01,
    loss_function='MultiCrossEntropy'
).fit(X,Y)

Problem:

I get the following error:

94, in train_model_pandas ).fit(X,Y) File "/usr/local/lib/python3.10/site-packages/catboost/core.py", line 5128, in fit self._fit(X, y, cat_features, text_features, embedding_features, None, sample_weight, None, None, None, None, baseline, use_best_model, File "/usr/local/lib/python3.10/site-packages/catboost/core.py", line 2355, in _fit self._train( File "/usr/local/lib/python3.10/site-packages/catboost/core.py", line 1759, in _train self._object._train(train_pool, test_pool, params, allow_clear_pool, init_model._object if init_model else None) SystemError: <method '_train' of '_catboost._CatBoost' objects> returned a result with an exception set

catboost version: 1.1.1 Operating System: windows 10, pyspark kernel but I am using pandas for training due to the nature of predictions. CPU: NA GPU: NA

For more context, this worked on an ec2 instance but failed to work on EMR. Thanks. After looking at my screen all day, I realized that turning verbose to False worked.

1. Try to use the most modern stable release (1.2.5), it might be that this bug is already fixed in it.
2. Can you create a fully end-to-end reproducible code example?

3. I realized that turning verbose to False worked.

This is strange, verbose settings should not cause any such errors.
