I recently published an article in towardsdatascience.com with some of the most popular data science course repositories on GitHub.
The ranking of these repositories was based on the number of forks they got on GitHub.
The most popular one is Stanford TensorFlow Tutorials with 4,072 forks, which is associated with Stanford’s CS20 course: TensorFlow for Deep Learning Research.
You can read the rest of the article with short descriptions for this and other popular repositories here.
