报错ImportError: cannot import name 'BaseEstimator'

有遇到这个问题的嘛

貌似是sklearn库的问题，我卸了numpy scipy scikt-learn又重装也没得用
网上查不到这个报错”ImportError: cannot import name 'BaseEstimator'“

代码：
from sklearn.datasets import load_iris
from sklearn.model_selection import train_test_split

def datasets_demo():

#获取并打印数据集
iris = load_iris()
print("鸢尾花数据集:\n", iris)
print("查看数据集描述:\n", iris["DESCR"])
print("查看特征值名字:\n", iris.feature_names)
print("查看特征值名字:\n", iris.data, iris.data.shape)


x_train,x_text,y_train,y_text=train_test_split(iris.data,iris.target,text_size=0.2,random_state=22)
prinit("训练集特征值:\n",x_train,x_train.shape)
