Hi @prateekgml thanks for your question. I can’t access the kaggle url, also do you mind sharing your code for train_x and train_y so we can reproduce the issue? Thanks

Thanks for sharing your code @prateekgml. The reason you are seeing this error is that train_y should be a pandas.Series instead of a pandas.DataFrame.
