Other than the SQL problem set, I didn't find any problem set / challenges on LeetCode that cover topics related to AI/ML. Wondering if any of you have come across one?

If not, how do you practice coding skill / modelling / data wrangling skill for AI/ML?

I think some good topics such a challenge could cover are:

• Pandas: Wrangling , selecting data, dealing with datetime or categorical variables
• Matplotlib & Seaborn: Plotting charts using these libraries
• Scikit Learn: Use the library to build some quick regression and Random Forest models
• Pytorch / Tensorflow : not sure how to practice this, but maybe the format could be complete a function as part of a given model, and prompter question to test out different functionalities
• Knowledge: True/False or multi-choice questions related to AI/ML

I know these contents are available in various places outside of Leetcode. But the value would be to have a curated collection that is gamified into challenges format. That would be super helpful for studying the topic.
