Hello, I’ve been getting a weird result from the 3rd exercise. I get this despite having the correct output. --------------------------------------------------------------------------- AssertionError Traceback (most recent call last) <ipython-input-42-2a50df79e115> in <m…

Hi @luiy0004 Please make sure you follow the steps of the implementations and also you can follow these hint step [Screenshot_٢٠٢٢١٢١٥-١٢٤٢٤٨] Thanks! Abdelrahman

Hey @luiy0004 , This kind of behaviour is mostly seen when your implementation uses one or more global variables, which you are not supposed to use, unless stated otherwise. Please ensure that you haven’t done the same. Let us know if this helps. Cheers, Elemento

Dear Abdelrahman, I tried following the hints and got the exact same error. LUIY0004

Dear Elemento, I checked the hint variables against the other sections. The hint variables do not seem to be global variables. This is the hint code that produced the error: # UNQ_C3 # GRADED FUNCTION: compute_information_gain def compute_information_gain(X, y, node_indices, feature): ""…

Hi @luiy0004 If we look at the failed test we can see that the function is producing a nan. What is nan and how is it produced? One way is division by 0. After nan has been produced any arithmetic with nan is nan. I would check everywhere division is performed in compute_information_gain() and …

Dear SamReiswig, Checking for where NaN could have been worked. Division by 0 was being tested in the compute entropy function. Strangely, that function passed all tests before I corrected it. Thank you very much for your help. Yours sincerely, LUIY0004

I have same issue as luly004…I went to check compute_entropy(y)…then only ‘/’ happens at p1 = len(y[y==1])/len(y), I added a condition on top: if len(y)>0…but still doesn’t work…please help…thanks!

Hi @Hui_Chen2 , I can’t tell what wrong from the description. Can you send me your code in a direct message and I’ll take a look.

I am facing the same issue. Was it resolved?

Hi @SiddharthPandey ,

Can you send me your code in a direct message and I’ll take a look.

Problem when trying to submit the last lab in the course
