Leetcode gets a bit of mixed feelings on tech forums, but the qualities I care about are: standardized questions to test knowledge, quick feedback, and the ability to practice and learn concepts without being part of an educational institution or creating your own custom project. So I'm more interested in those aspects, rather than as an interview tool.

Does such a thing exist for AI or Machine Learning? Maybe interactive problem sets that focus on making and running models in PyTorch. Or execute specific code yourself (with a given random seed) and put in the final result of training a model after N epochs. I'm not really sure how this is best done, just brainstorming a bit here.

Thanks for any suggestions.
