mlx-mol-cluster 0.2.0

Clustering molecules using Apple Silicon GPU

MLXMolCluster

Leverage Apple Silicon to cluster molecules using MLX.

At the time of writing, the project contains two clustering methods:

• Butina
• KMeans

Additional clustering methods will be added over time.

Examples have been written and can be found here.

Installation

Install from PyPI:

pip install mlx-mol-cluster

Or install directly from the GitHub repository:

pip install git+https://github.com/tlint101/MLXMolCluster.git

Example

The following is an example of clustering molecules using Butina on MLX.

# generate molecular fingerprints
fp_gen = rdFingerprintGenerator.GetRDKitFPGenerator(fpSize=1024)
rdkit_fps = [fp_gen.GetFingerprint(mol) for mol in mol_list]

# convert to mlx arrays
mlx_fp = fp_to_mlx(rdkit_fps)

# Butina cluster
butina_mlx = butina(mlx_fp)

A speed comparison can be seen at the tutorial section. The runs were performed on a M2 Pro chip (10 CPU, 16 GPU)

NOTE: The figure can be misleading. The figure shows the clustering speed of already generated molecular fingerprints. The main bottleneck of clustering remains on the generation of molecular fingerprints. This is done on the CPU before being converted to the GPU. Depending on the number of molecules, this can be time intensive.
