I’m working through the exercises in our data analytics course, but I’m having some trouble with Exercise 1 and Exercise 7.
In Exercise 1, I get the following error: “Failed test case: The keys in params dictionary do not match the expected values. The keys are correct, but the values do not match the expected ones.”
In Exercise 7, the error is: “Object required for grading not found. If you haven’t completed the exercise this is expected. Otherwise, check your solution as grader omits cells that throw errors.”
The confusing part is that the answers I get seem to be correct, but these messages still appear.
Also, I can’t retrieve the first version of the code (the original starting code) to compare and understand what might be wrong.
If anyone has encountered similar issues or has any advice, I’d really appreciate your help.
Hi! Thank you for reporting. We’ll be updating the grader for this assignment tomorrow to avoid the common problem in Exercise 1. To get a fresh copy of the lab (i.e. refreshing your workspace), please refer to the Jupyter Lab section of this post. Hope this helps.
Hi! Thanks for answering. The reason why I can’t refresh the Jupiter notebook is that when I was writing the exercises i somehow delelted the original file, probably i pressed something. If you could help me about that problem would be great.
