name 'load_boston' is not defined

这个错误是因为你使用了load_boston函数，但是没有导入相应的库。load_boston函数是在sklearn.datasets模块中的，所以你需要导入sklearn.datasets库。你可以使用以下代码进行导入：

from sklearn.datasets import load_boston

然后你就可以使用load_boston函数了，例如：

boston = load_boston()

这样就可以成功加载波士顿房价数据集了。

name all_titles is not defined

This error message indicates that you are trying to reference a variable named "all_titles" that has not been defined in your code. To fix this error, you need to define the variable "all_titles" before referencing it in your code. For example, you could define "all_titles" as an empty list like this:

all_titles = []

Alternatively, you may have misspelled the variable name or it may not be in the correct scope. Double-check your code to make sure that the variable is defined where you expect it to be and that it is spelled correctly.
