Hello, I’m having trouble with the first assignment of week 2 where I get the error Tests failed on 1 cell(s)! These tests could be hidden. Please check your submission. and my grade stays at 88%. I’ve done all of the exercises the way it was asked and I didn’t change the structure or used global variables. How can I debug it? Thanks ---

Hi, Ethan. Welcome to the community! The version of the notebook might have been updated. Please update it and then run all the cells from the beginning. Here’s the [link](https://www.coursera.org/learn/neural-networks-deep-learning/supplement/iLwon/h-ow-to-refresh-your-workspace) ---

I followed the instructions but I’m still getting 88/100. Is there a way to know which test is failing? ---

Hello, I’m having this same problem on W2A1. My grade stays at 88% even though all of the tests are passed and I didn’t change the structure of the assignment, global variables, etc. Using the “Validate” button indicates that all tests are passed. I tried updating the notebook and saving before submission with no results. I did not hard-code any values. Any other thoughts on how this might be resolved? ```auto [ValidateApp | INFO] Validating '/home/jovyan/work/submitted/courseraLearner/W2A1/Python_Basics_with_Numpy.ipynb' [ValidateApp | INFO] Executing notebook with kernel: python3 Tests failed on 1 cell(s)!

Diana! It seems that you have hard-wired any of the values or might have used global variables within the function. Just go through it once. Hope, things would get resolved. ---

Hi, I have similar error in W3A1 where I am getting 75/100 since grader is unable to identify back\_prop function. Kindly help. ---

Just to close the loop here: I have contacted Shubham by DM and we have figured out the issue here. Somehow some incorrect code got added to one of the function cells. ---

Just to close the loop on the public thread here, we had a DM conversation so that we could share the code and found that the issue is one instance of hard-coding the parameter values inside a function body so that it happened to match the value passed in the test case. Not sure why the grader has to be mysterious about which function was the issue, but we’ve pointed this out the course staff in the past and apparently it’s not easy to get around the way the grader works in this instance. ---

Hello, I am having the same problem but in coures2 - week1 - gradient checking assignment of Deep learning specialization. All graded cells pass the autograder tests but marking comes back as 60/100 I did not modify any of the non graded cells nor used global variables. I tried to start fresh by clicking the question mark button and reboot server but got the same feedback from grader. This is the error code: [ValidateApp | INFO] Validating ‘/home/jovyan/work/submitted/courseraLearner/W1A3/Gradient\_Checking.ipynb’ [ValidateApp | INFO] Executing notebook with kernel: python3 Tests failed on 1 cell(s)!

We’ll need to look at your code, since the grader is not offering any help here. We can’t do that in a public thread, but please check your DMs for a message from me about how to proceed. You can recognize DMs (Direct Messages) in your feed by the “envelope” icon. ---
