报错：ValueError: labels must be unique if ordered=True; pass ordered=False for duplicate labels。

提示信息翻译：当 ordered=True 的时候，labels的值必须是唯一的，而我的labels_2里面有重复值，

解决办法：

a = pd.cut(df_10min_1[spectral_wind_profile.wd_hub], bins=bins_2, labels=labels_2,
                                          include_lowest=True, ordered=False)
