def read_events_labels(file1, file2, data_path='/home/ibcn079/data/Data/'):
    a = pd.read_csv(data_path+file1,header=None)   #### I don't konw how to get it?
    a = a.values

    b = pd.read_csv(data_path+file2,header=None)  #### I don't konw how to get it?
    b = b.values

Thank you very much!
