<p>Scikit-learn patching functionality in daal4py was deprecated and moved to a separate package, <a class="reference external" href="https://github.com/intel/scikit-learn-intelex">Intel(R) Extension for Scikit-learn*</a>.
All future patches will be available only in Intel(R) Extension for Scikit-learn*. Use the scikit-learn-intelex package instead of daal4py for the scikit-learn acceleration.</p>
