你的第一个问题是关于 `load_boston` 函数已经从 scikit-learn 中移除的问题。这是一个事实,并且自版本1.2以来已经移除。这个函数是用于加载波士顿房价数据集的。如果你需要使用该数据集,你可以从其他途径获取数据并在 scikit-learn 中使用。

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.

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.
