Jovian.ai has a good collection of free courses and fun activities for Data Enthusiasts. It also offers a Python notebook running environment with limited hardware capabilities to learn and apply machine learning and data science job works. Review collected by and hosted on G2.com.

Notebook schedule run is not an option for Jovian.ai which I was looking out for. Also, the courses hopefully will get more and more with detailed courses about new technologies. Review collected by and hosted on G2.com.
