Best Open-Source Machine Learning Libraries in 2025
The era of machine learning is changing day by day, and innovation is being directed by open-source libraries.
TensorFlow
One of the most widely used open-source machine learning libraries is still TensorFlow.
PyTorch
Because PyTorch is user-friendly and has a dynamic computational graph, it has emerged as the preferred option for machine learning developers and researchers.
Scikit-learn
A popular open-source library called Scikit-learn was created for common machine learning tasks like dimensionality reduction, clustering, regression, and classification.
Keras
A deep learning library called Keras makes it simple for users to create neural networks. Originally created as a high-level TensorFlow interface, it expanded into a separate library in 2025.
As of 2025, the best-in-class tools for creating AI are still open-source machine learning libraries like TensorFlow, PyTorch, Scikit-learn, and Keras.
