Hi!
First post and really enjoying the courses!
But I’m having trouble with the Capstone, Exercise 6 when submitting. When graded I get
“Unable to find object required for grading in your code.”
Really annoying as it matches the expected output and I don’t believe I’ve changed any of the variables and everything required is in the graded cell. Is there something else that should be looked out for, or is someone able to take a look?
Many thanks
I’m not a mentor for that course.
But generally, that error means you have modified something in the notebook that the grader does not enjoy. For example, adding, deleting, or modifying a cell in an unexpected way, can break the grader.
Yeah this is what I figured but as I say, can’t recall modifying anything in that way, and no added cells etc. Everything else has graded fine too so definitely something within this cell. Would be helpful if I could see the original exercise to see if I’ve inadvertently modified a variable name or something
I figured it, it was due to the way I had used sqrt
