我尝试在python中使用elasticsearch构建模型，但遇到此错误，我可以执行一次，但由于此错误，现在无法再次运行

import pandas as pd

df = pd.read_csv("salaries.csv")
df.head()

inputs = df.drop('salary_more_then_100k',axis='columns')

target = df['salary_more_then_100k']

from sklearn.preprocessing import LabelEncoder
le_company = LabelEncoder()
le_job = LabelEncoder()
le_degree = LabelEncoder()

inputs['company_n'] = le_company.fit_transform(inputs['company'])
inputs['job_n'] = le_job.fit_transform(inputs['job'])
inputs['degree_n'] = le_degree.fit_transform(inputs['degree'])

inputs

inputs_n = inputs.drop(['company','job','degree'],axis='columns')

inputs_n

target

from sklearn import tree
model = tree.DecisionTreeClassifier()

model.fit(inputs_n, target)

from eland.ml import MLModel
from elasticsearch import Elasticsearch

es = Elasticsearch(hosts='http://localhost:9200')

es_model = MLModel.import_model(es_client=es,
                                model=model,
                                model_id='salaries-model',
                                feature_names=list(df.columns),
                                es_if_exists='replace'
)

当我运行es_model行时，我得到这个错误-〉AttributeError：“Elasticsearch”对象没有属性“options”
我做错了什么，谁能告诉我
