i downloaded the ipynb exercise files but couldnt open it

Hi Szeyue! Thanks for reaching out! To launch the *.ipynb files, you can't just double-click on them; you have to upload and launch them in Jupyter, much like shown in the following lecture. https://learn.365datascience.com/courses/introduction-to-jupyter/welcome-to-the-course Hope this helps. Best, Martin
