I am getting the following error from the Grader for the third graded function of the second coding assignment of Course 5, Week 1: Code Cell UNQ_C3: Unexpected error (KeyError(‘da_next’)) occurred during function check. We expected function optimize to return Test 3 failed. Please check that this…

I actually did just figure it out. The problem is that the ‘rnn_backward’ function uses a ‘gradients’ dictionary that includes more variables than the one in the actual assignment. Specifically, it includes ‘da_next’. Crucially, this means that it is possible to check whether during the ‘optimize’ f…

Hello Geoffrey, Can you please share the screenshot of your output. Regards DP

Sure. I’ll include both the grader output and the code output. I don’t know if it’ll help at all, but here it is: [Screenshot 2023-08-22 231019] [Screenshot 2023-08-22 231113]

is this week 1 first assignment. there are 3 assignments in week 1, please mention assignment name

Your screenshot does help a lot in finding the error in finding solution, thank you

For the record, it is Course 5 – Week 1 – Assignment 2 – Exercise 3, but I have now explicitly added the name of the assignment (Dinosaur Island) to the title of the thread. EDIT: To clear up what seems to be some confusion, here is the prompt immediately before the code cell: [Screenshot 2023-08…

I don’t see any explanation of the problem in that thread. The poster replies immediately to his own question by saying he needs help with a different problem than the one he started asking about. I am also confused by your statement. I am pretty sure that I am defining the function correctly since…

Most of this problem is due to code in the notebook using a global variable that isn’t supported by the grader. Did you address this issue? I hope you have an understanding of global variables. Check the below comment to make you more understand about where you could have gone wrong. and if you st…

good you got it, it basically it is not an error but the grader requires us to the function code the way they want and when it is not implemented that way, the grader cell does not pass even if you have got the expected output.

I am curious what you needed to change in your notebook to resolve the issue.

Hello,

Please refer this post

If you are still not able to get from this hint, you are basically not defining one of your code with the right function. Let me know if still running into trouble.

P.S. note you need to define the forward and backward propagation accordingly in the both code lines.

Regards
DP
