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

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.
