Description (include relevant info but please do not post solution code or your entire notebook)
I faced the issues of There was a problem compiling the code from your notebook. Details: operands could not be broadcast together with shapes (3,) (200,) and received zero points. Anything that I should do before submissions?
What that means is that somewhere in your code for the assignment, your code is making the grader script crash with a runtime error. This is why it gives the same error for all of the exercises.
So you need to look for somewhere in your code that you have hard-coded the size of some variable or matrix.
The grader uses different test cases than the ones that are built into the notebook. So your code must work for any possible test case.
The problem is that if there is any exception that gets thrown on any of the sections, then the grader can’t complete execution and you get the same error message for every section.
So now you need to figure out how to “drill down” on Tom’s point about hard-coding of dimensions. If you pass all the tests when you run them locally in the notebook, then you must be hard-coding things to match the particular test cases. It could be a hard-coded dimension or another way to cause that type of error is to reference global variables from the body of your function, instead of referencing the formal parameters of the function.
