I meet the same question, could you let me know what you solve the problem?

I solved this problem by changing the way it accesses the target column.

In the file train.py, within the function 'perform_kfold_cv', change df.flags to df['flags']. The first returns the attribute of the dataframe, while the second accesses the data within the flags column
