Top Python Libraries for Deep Learning, Natural Language Processing & Computer Vision


In a previous post, we had a look at the top python libraries for data science, data visualization, and machine learning. This time, we look at the top libraries for deep learning, natural language processing, and computer vision. These categories really don’t need any further clarification.

This separation and classification is arbitrary, in some instances more than others, but we have done our best to group tools together by intended use case, hoping this is most useful for readers.

Clearly not all NLP and CV work these days is performed using deep learning techniques, but as the trends move toward such techniques for state of the art results, we stand by this otherwise arbitrary categorization logic.

Our list is made up of libraries that our team decided together by consensus was representative of common and well-used Python libraries. Also, to be included a library must have a Github repository. The categories are in no particular order, and neither are the libraries included within each. We contemplated constructing an ordering arbitrarily by stars or some other metric, but decided against it in order not explicitly stray from placing any perceived value or importance of the libraries within. Their listing here, then, is purely random. Library descriptions are directly from the Github repositories, in some form or another.

Thanks again to Ahmed Anis for contributing to the collection of this data, and to the rest of the KDnuggets staff for their inputs, insights, and suggestions.

Note that the visualization below, by Gregory Piatetsky, represents each library by type, plots it by stars and contributors, and its symbol size is reflective of the number of commits the library has on Github on a logarithmic scale.

And, so without further ado, here are the 30 top Python libraries for deep learning, natural language processing & computer vision, as best determined by KDnuggets staff.
