C2_W1_Assignment - Grading time out problem

Jay_M_Gonzalez · June 2, 2023, 10:55am

Hi all, I’m facing an issue when trying to submit my the assignment. First it takes ages to run the cells and when I try to submit it I get a time out error.

And this is the error I get when trying to run the test.

I have the code in my GB but not sure if I can post it here due to Code of Honor.
In a previous post, someone was having similar output from the tests, but I don’t think is the same case as I haven’t touched anything outside delimited code areas.

Thanks for your help.

I run the notebook in my local computer and still getting the same errors. It took plus 5 minutes to complete grading the work, or anything related with f_of_omega function.

    "In this assignment you will solve a simple optimization problem for a function of one variable. Given a dataset of historical prices of a product from two suppliers, your task is to identify what share of the product you should buy from each of the suppliers to make the best possible investment in the future. Stating the problem mathematically, you will construct a target function to minimize, evaluate its minimum and investigate how its derivative is connected with the result."

That’s the notebook code in case anyone wants to have a look.

Thanks

Hi @jonrico I wonder if you can help this learner with his issue, I see you are a mentor for this specialization.

Hi @Jay_M_Gonzalez

For your f_of_omega function, simply implement this equation for f as in the instruction

Remember that when you multiply an array with a scalar, it will give an array as a result as well. So that you do not need to run an iteration to calculate f.

Let me know if you still encounter another problem.

Thanks both for help, it’s working now
