我得到这种类型的错误：TypeError：'int'和'str'的实例之间不支持'<'

Question

from sklearn.preprocessing import LabelEncoder
var_mod = ['Gender','Married','Dependents','Education','Self_Employed','Property_Area']
le = LabelEncoder()
for i in var_mod:
    data[i] = le.fit_transform(data[i])

我尝试通过编码类别将所有类别变量转换为数字。但是，出现以下错误。

  

TypeError：“ int”和“ str”的实例之间不支持“ <”

Answer 1

通过以下示例：https://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.LabelEncoder.html

并检查此内容：

from sklearn import preprocessing

le = preprocessing.LabelEncoder()

var_mod = ['Gender','Married','Dependents','Education','Self_Employed','Property_Area']

le.fit(var_mod)

print(le.transform(['Self_Employed','Dependents']))

print(le.transform(['Gender','Married','Dependents','Education','Self_Employed','Property_Area']))
