Pandas的mode()函数用于计算DataFrame或Series中出现频率最高的值(即众数)。在早期的Pandas版本中,mode()函数确实包含了一个numeric_only参数,该参数用于指定是否仅对数值型列进行操作。然而,在Pandas的后续版本中,这个参数已经被弃用,因此在尝试使用它时会遇到错误,如“mode() got an unexpected keyword argument 'nu...
按DataFrame.select_dtypes选择数值列：
步骤1:检查代码中是否有使用到DataFrameGroupBy.mean方法。步骤2:如果有使用到该方法,确保你没有在调用时显式设置numeric_only参数为True或False。步骤3:在调用DataFrameGroupBy.mean方法时,添加numeric_only参数,并将其值设置为True或False。示例代码: import pandas as pd df = pd.DataFrame({'A': [1, 2, 3,...
When ordinal data (categorical dtype with defined order) presented in dataframe, it seems natural to expect that rank correlation still be computed when using numeric_only = False. For example, something like this should work: import pandas as pd df = pd.DataFrame({'workweek' : [4, 5, 6...
