A curated list of awesome machine learning frameworks, libraries and software (by language). Inspired by awesome-php. Other awesome lists can be found in the awesome-awesomeness list.

Not strictly limited to “machine learning” as it offers resources on data analysis, visualization, etc.
With a list of 576 resources, I am sure you will find something new!
