报错`load_boston` has been removed from scikit-learn since version 1.2.

这个报错是因为从 Scikit-learn 1.2 开始,`load_boston` 已被移除。它是一个加载波士顿房价数据集的函数。如果你需要使用波士顿房价数据集,你可以使用以下代码:
``` python
from sklearn.datasets import fetch_openml
boston = fetch_openml(name='boston')
```
这个代码会从 OpenML 数据库中获取波士顿房价数据集,并将其作为一个 Bunch 对象返回。你可以使用`boston.data`来获取数据集的特征,使用`boston.target`来获取目标变量(即房价)。

I apologize for the confusion. You are correct, the `load_boston` function has been removed from scikit-learn since version 1.2. Instead, you can use the `fetch_openml` function to download the Boston dataset from the OpenML repository. Here's an example:
```python
from sklearn.datasets import fetch_openml
# Load the Boston dataset
boston = fetch_openml(data_id=531)
# Get the feature matrix and target vector
X = boston.data
y = boston.target
# Print the shape of the feature matrix and the first 5 rows
print(X.shape)
print(X[:5, :])
# Print the shape of the target vector and the first 5 elements
print(y.shape)
print(y[:5])
```
In this example, we use the `fetch_openml` function to download the Boston dataset. Then, we extract the feature matrix `X` and the target vector `y` from the downloaded dataset.
Please make sure you have scikit-learn version 1.2 or later installed in your Python environment to use this method. If you encounter any issues or have further questions, feel free to ask.
load_boston` has been removed from scikit-learn since version 1.2.
Yes, that's correct. The `load_boston` dataset has been removed from scikit-learn since version 1.2. This was due to the fact that the dataset is now widely available from other sources, such as the UCI Machine Learning Repository. In addition, scikit-learn now focuses more on machine learning algorithms and tools, rather than datasets. However, users can still access the `load_boston` dataset through other means, such as loading it from the UCI repository or using other libraries.
