Will scikit-learn utilize GPU?

Tensorflow only uses GPU if it is built against Cuda and CuDNN. By default it does not use GPU, especially if it is running inside Docker, unless you use nvidia-docker and an image with a built-in support.

Scikit-learn is not intended to be used as a deep-learning framework and it does not provide any GPU support.

Why is there no support for deep or reinforcement learning / Will there be support for deep or reinforcement learning in scikit-learn?

Deep learning and reinforcement learning both require a richvocabulary to define an architecture, with deep learning additionallyrequiring GPUs for efficient computing. However, neither of these fitwithin the design constraints of scikit-learn; as a result, deeplearning and reinforcement learning are currently out of scope forwhat scikit-learn seeks to achieve.

Will you add GPU support in scikit-learn?

No, or at least not in the near future. The main reason is that GPUsupport will introduce many software dependencies and introduceplatform specific issues. scikit-learn is designed to be easy toinstall on a wide variety of platforms. Outside of neural networks,GPUs don’t play a large role in machine learning today, and muchlarger gains in speed can often be achieved by a careful choice ofalgorithms.

I'm experimenting with a drop-in solution (h2o4gpu) to take advantage of GPU acceleration in particular for Kmeans:

try this:

from h2o4gpu.solvers import KMeans#from sklearn.cluster import KMeans

as of now, version 0.3.2 still don't have .inertia_ but I think it's in their TODO list.

EDIT: Haven't tested yet, but scikit-cuda seems to be getting traction.

EDIT: RAPIDS is really the way to go here.

From my experience, I use this package to utilize GPU for some sklearn algorithms in here.

The code I use:

from sklearnex import patch_sklearnfrom daal4py.oneapi import sycl_contextpatch_sklearn()
