Grader Error: Not able to detect variables

Course Q&A TensorFlow: Advanced Techniques Specialization Custom Models, Layers and Loss Functions with TF

Hello everyone

I went through all the conversations about the grader bug. I have updated the lab version, passed all public tests and clearly defined all the variables. Even after getting the desired output, I still got a 03/10 for my submission.

The name of the assignment file is: C1W1_Assignment

Hi Chris @chris.favila, I think we have a similar problem like we have encountered before. I think it was updates…I ran the lab myself and it only gets 3/10.

3

Hi Gent! Unfortunately, I can’t replicate the issue. I tried submitting now and got 10/10. Already sent a direct message to Aaditya so I can get a copy of the notebook. You can also send yours to me if you want so we can check if there’s a common pattern that leads to the grader bug. Thanks!

4

I actually ran his notebook but it passed the tests on the coursera jupyter page so I thought there might be a problem, but also the problem might be on his notebook!

5

Ok will check! Thanks!

Hi Aaditya! It seems you’ve modified the URL variables. Please use the default strings provided in the boilerplate to get the perfect score. Please only modify lines with the # YOUR CODE HERE tag. Hope this helps!

Hello sir,

I tried using the default strings and did not modify any other lines except the # YOUR CODE HERE tag. I still got the same error.

8

Hmm… That is strange. Can you refresh your notebook one more time (do not put your solutions yet) and then send the blank notebook to me via direct message? Thanks.

9

Sorry forgot to mention to also send the notebook of your most recent attempt that is still getting the error. In your original solution, I just changed the URL strings and got the perfect score.

10

Hello, Sir.
Yes. You’re correct. From the blank notebook description, I thought that I needed to go to the particular dataset URL and modify the cell. I sincerely apologise for that. Maybe we can remove the link from the notebook and warn users not to change the URI string as a solution. Thank you very much for your time and efforts.

14

can you help???

how?? add a photo please

@Vipin21,
The original problem this topic was addressing was due to the URL value being changed in this cell:

Other reasons you might see a NameError: name 'white_df' is not defined error is if this cell was not uncommented, or if the cell was not run after it was uncommented.

Please make sure you have:

  • followed the instructions at the top of the cell to uncomment the cell
  • and then ONLY edit the part of the cell where it says # YOUR CODE HERE
  • then execute the cell

As long as you don’t change anything else, white_df should be defined, and you should pass the unit test if you properly filled in the # YOUR CODE HERE section.

Wendy thank you so much for the silly mistake I was doing, just cleared the test :grimacing:

Hello @Siya_Ghode
You are not suppose to share assignment used to grade your codes on post threads. It is against community guidelines. rather share a screenshot of your grader output showing why you failed the tests and also create a new post whenever you have any issue rather than posting on old threads as chances of misunderstanding/missing your posts getting higher.

Regards
DP
