How to load dataset at 'Google Colab' page to run the assignment successfully?

As Rashmi says, the point is that just copying the notebook itself is not enough. There is a whole tree of supporting files that you need along with the notebook, if you want to run the notebook in some different environment. There is a topic on the DLS FAQ Thread about how to download all the files. But note that the course has given you a working environment on the Coursera website, so it’s not our job to be your IT support staff if you choose to run things in a different environment. You’ll need to develop your own skills for solving that type of problem, otherwise it just never ends, right? :nerd_face:
