Disclaimer
Keep in mind that the course is in an inactive self-paced mode, the only material that's kept up-to-date is located in the mlcourse_ai_jupyter_book/book folder.
Small typos in Jupyter notebooks can be addressed directly from mlcourse.ai.
- click GitHub logo in the top-right corner
- click "Open Issue", this will bring you to a new GitHub issue called smth like "Issue on page /book/topic01/topic01_pandas_data_analysis.html"
- add a comment describing the typo/bug/fix (obligatory).
If you think, there is a more serious error in course materials (ex. incorrect math designation), you can open an Issue right away.
If you are about to open a Pull Request, test jupyter-book build on your branch as described here in Readme. There are no formal tests or CI/CD, but you should be able to see that jupyter-book builds and runs with no issues.
