ValueError: cannot reindex from a duplicate axis

解决思路

def target_plot_interact(df, features, feature_names, target, num_grid_points=None, 
 grid_types=None, 
    percentile_ranges=None, grid_ranges=None, cust_grid_points=None, 
     show_percentile=False, 
    show_outliers=False, endpoint=True, figsize=None, ncols=2, annotate=False, 
     plot_params=None):
    """Plot average target value across different feature value combinations (feature grid 
     combinations)
    
    Parameters
    ----------
    
    df: pandas DataFrame
    data set to investigate on, should contain at least
    the feature to investigate as well as the target
    features: list
    two features to investigate

值错误:不能从重复的轴重新索引

解决方法

features: list，two features to investigate，经过分析，features是需要指定两个不同的特征，即x和y，而且x=y，之所以，出现上述错误，是因为定义的两个特征完全一致，导致不满足该函数方法！所之需要将其中一个特征名改为另一个即可！

features=[num_col2plot,num_col2plot02]
