导入from sklearn.datasets import load_boston 报错内容: `load_boston` has been removed from scikit-learn since version 1.2.解决办法: 1、将数据下载到本地使用 2、降低 scikit-learn版本:pip install sc…
`load_boston` has been removed from scikit-learn since version 1.2.,也就是1.2库中的load_boston方法被移除:给的解决办法: 2、可以使用如下方法解决: import pandasaspd import numpyasnp import sklearnfromsklearn import datasets #导入数据集合 data_url="http://lib.stat.cmu.edu/datasets/boston"raw_d...
应该是scikit-learn版本的问题,导致boston这个东西不能在这里使用,就出现这个错误; 问题解决 我们先将***换成这些(已经在报错里面明确给出来了): data_url="http://lib.stat.cmu.edu/datasets/boston"raw_df= pd.read_csv(data_url, sep="\s+", skiprows=22, header=None)data= np.hstack([raw_df.va...
from sklearn import datasets 是Python中用于从sklearn(即Scikit-learn库)导入datasets模块的语句。以下是该语句作用的详细解释: 语法作用: from sklearn import datasets:这条语句的作用是从sklearn库中导入datasets模块。sklearn是Python中用于机器学习的一个广泛使用的库,而datasets模块则提供了许多用于机器学习实验...
