类型错误：& 不支持的操作数类型：'float'和“布尔”使用 .loc 时

Question

给定以下 DataFrame -

json_path	报告组	实体/分组	实体 ID	调整后的值（今天，没有Div，美元）	调整后的 TWR（本季度，无 Div，美元）	调整后的 TWR（年初至今，无 Div，美元）	年化调整后TWR（自成立以来，无 Div，美元）	调整值（无 Div，美元）	TWR 审计说明
data.attributes.total.children。[0] .孩子。[0].孩子。[0]	巴拉克家族	威廉和鲁珀特信托	9957007	-1.44				-1.44
data.attributes.total.children.[0].children.[0].children.[0].children.[0]	兵营家庭	现金	-	-1.44				-1.44
data.attributes.total.children.[0].children.[0].children.[1]	Barrack Family	Gratia Holdings No. 2 LLC	8413655	55491732.66	-0.971018847	-0.971018847	11.52490309	55491732.66
data.attributes.total.children.[0].children.[0].children.[1].children.[0]	Barrack Family	投资级固定收益	-	18469768.6				18469768.6
data.attributes.total.children.[0].children.[0].children.[1].children.[1]	Barrack Family	高收益固定收益	-	3668982.44	-0.205356545	-0.205356545	4.441190127	3668982.44

我有一个 def dataset_creation() 函数，它使用 .loc 剔除不符合条件的数据帧行在将数据框保存为之前的条件perf_asset_class_df。随后，def twr_exceptions_logic() 函数应该删除 Entity/Grouping 列值 != 'Cash' 的行，并且如果调整后的 TWR（本季度，无 Div，美元），调整后的 TWR（年初至今，无 Div，美元）或年调整值TWR (Since Inception, No Div, USD)` is == " [empty]

功能：这里是功能，如所述 -

def databases_creation():
    df = data_cleansing()
    
#   CREATING DATAFRAME FOR PERF. BY ASSET CLASS (EX. ILLIQUID) - STANDARD REPORT PG.4
    perf_asset_class_df = df[df['json_path'].str.contains(r'(?:\.children\.\[\d+\]){4}')]

    return perf_asset_class_df

AND

def twr_exceptions_logic():
    perf_asset_class_df = databases_creation()

    m1 = perf_asset_class_df.loc[(perf_asset_class_df['Entity/Grouping']!= 'Cash')]
    m2 = perf_asset_class_df[['Adjusted TWR (Current Quarter, No Div, USD)',
                              'Adjusted TWR (YTD, No Div, USD)',
                              'Annualized Adjusted TWR (Since Inception, No Div, USD)']].eq('').any(1)
    perf_asset_class_df.loc[m1&m2]
    
    return perf_asset_class_df

问题： 我得到一个TypeError: unsupported operand type(s) for &: 'float' and 'bool' 指向 def twr_exceptions_logic()，特别是perf_asset_class_df.loc[m1&m2]

有人对我的代码可能出现问题的地方有任何提示/技巧吗？
