We update the top AI and Machine Learning projects in Python. Tensorflow has moved to the first place with triple-digit growth in contributors. Scikit-learn dropped to 2nd place, but still has a very large base of contributors.

Getting into Machine Learning and AI is not an easy task. Many aspiring professionals and enthusiasts find it hard to establish a proper path into the field, given the enormous amount of resources available today. The field is evolving constantly and it is crucial that we keep up with the pace of this rapid development. In order to cope with this overwhelming speed of evolution and innovation, a good way to stay updated and knowledgeable on the advances of ML, is to engage with the community by contributing to the many open-source projects and tools that are used daily by advanced professionals.

Tensorflow has moved to the first place with triple-digit growth in contributors. Scikit-learn dropped to 2nd place, but still has a very large base of contributors.
Compared to 2016, the projects with the fastest growth in number of contributors were

  1. TensorFlow, 169% up, from 493 to 1324 contributors
  2. Deap, 86% up, from 21 to 39 contributors
  3. Chainer, 83% up, from 84 to 154 contributors
  4. Gensim, 81% up, from 145 to 262 contributors
  5. Neon, 66% up, from 47 to 78 contributors
  6. Nilearn, 50% up, from 46 to 69 contributors
Also new in 2018:
  1. Keras, 629 contributors
  2. PyTorch, 399 contributors

Fig. 1: Top 20 Python AI and Machine Learning projects on Github.
Size is proportional to the number of contributors, and color represents to the change in the number of contributors - red is higher, blue is lower. Snowflake shape is for Deep Learning projects, round for other projects.

We see that Deep Learning projects like TensorFlow, Theano, and Caffe are among the most popular.

The list below gives projects in descending order based on the number of contributors on Github. The change in number of contributors is versus 2016 KDnuggets Post on Top 20 Python Machine Learning Open Source Projects.

We hope you enjoy going through the documentation pages of each of these to start collaborating and learning the ways of Machine Learning using Python.
