TypeError: '' not supported between instances of 'float' and 'str'

var_to_encode = ['Device_Type','Filled_Form','Gender','Var1','Var2','Mobile_Verified','Source']
for col in var_to_encode:data[col] = le.fit_transform(data[col])

报错：TypeError: '>' not supported between instances of 'float' and 'str'

修改为：

data[col] = le.fit_transform(data[col].astype(str))亲测可用
