A curated list of awesome machine learning frameworks, libraries and software (by language). Inspired by awesome-php.
IMPORTANT NOTE ON PRs:
As of April 2026, too many PRs are being generated by LLMs, this is no longer fun or manageable. If you want to contribute to this repo, email me at joseph dot misiti @ hey dot com to prove you're human with a link to your PR and I'll merge it. Thank you for your understanding.
Also, a listed repository should be deprecated if:
Repository's owner explicitly says that "this library is not maintained".
Not committed for a long time (2~3 years).
