"Note: The default value for the `n_init` hyperparameter above will change from 10 to `\"auto\"` in Scikit-Learn 1.4, so I'm setting it explicitly to 10 to keep this notebook stable."
"**Warning**:\n",
"* There was a change in Scikit-Learn 1.3.0 which affected the random number generator for `KMeans` initialization. Therefore the results will be different than in the book if you use Scikit-Learn ≥ 1.3. That's not a problem as long as you don't expect the outputs to be perfectly identical.\n",
"* Throughout this notebook, when `n_init` was not set when creating a `KMeans` estimator, I explicitly set it to `n_init=10` to avoid a warning about the fact that the default value for this hyperparameter will change from 10 to `\"auto\"` in Scikit-Learn 1.4."
