TensorFlow: Advanced Techniques Specialization

I doing a TensorFlow: Advanced Techniques Specialization course but i did not able to complete Week 1: Multiple Output Models using the Keras Functional API lab the URL of the red wine dataset is not opened.

I moved this thread into the correct category for you Deepak, am I correct assuming it is for week 1 of course 1?

Week 1: Multiple Output Models using the Keras Functional API lab the URL of the red wine dataset is not opened it shows that server error


Are you still having the problem? I just checked the URL in my notebook and it’s working fine.

And the Dataset must be already downloaded in your environment: remember that for pass the grade yo d0n’t have to change de he URI.

URL of the white wine dataset

URI = ‘./winequality-white.csv’

Let us know if you are still experiencing problems.

Yes iam facing the same problem

Iam doing Custom Models, Layers, and Loss Functions with TensorFlow course in coursera I did not able to complete the week 1 assignment lab i thing there was problem in this link

URL of the red wine dataset

URL = ‘http://archive.ics.uci.edu/ml/machine-learning-databases/wine-quality/winequality-red.csv

The link given above is not opened



Here you can found the .csv

The full source link is the same that you sent. I can download without problems the .csv from the link.

But are you sure that you need to dowload the dataset, since I remember it wasn’t necessary. The Filke must be alreade saved in your workspace. And you only need to indicate

URL of the white wine dataset

URI = ‘./winequality-white.csv’

to acces it.

Yo can check if the file is in your workspace in the LAB_FILES section in the notebook (Upper right corner) The file must be under the directory release > W1_asignement,

I not able to complete week 1 lab


I think that you just should the change the value in URI by ‘./winequality-white.csv’ instead of the full path. and yo will have acces to the Dataset.

I not able to complete it can you help me

Hi Deepak, what problem do you have?

It’s difficult for me to help, I can assist you in specific questions or try to guide if you have some doubts.

Now the Coursera platform is experiencing a problem with the submission of the notebooks, can it be your problem?

______ This is a message related to the problem with the submission of the assignments.____

Hi Aahil! I’m sorry for this experience. We’ve already reported it to Coursera and they are looking into it. In the meantime, can you try this and see if your notebook is graded?

  1. From the blank notebook, click File -> Open.
  2. Tick the running notebook.
  3. Click Shutdown then Duplicate.
  4. Rename the old notebook (any filename).
  5. Rename the duplicate to the original filename (basically, just remove the -Copy1 string).
  6. Open this newly renamed notebook.
  7. You should be able to save this and also see the submit button after a minute.

You might see an error about checkpoints failing. I think that’s okay because that’s related to the permissions of the hidden .ipynb_checkpoints folder. That is not needed for grading.

Hope this works while the fix is ongoing. Please let me know. Thank you!

How to i reset this lab

Try it:

Coursera has informed us that this issue has been resolved. Please get the latest copy of the notebook and let us know if it fixes it. Before doing that, maybe rename the old notebook first.

If you are still having trouble with trying the “get latest solution” above, please comment below letting us know the error you are getting before trying the “additional things”.

And if it works, also let us know then as well.


Additional things to try:

As posted by @jonathanpsculley: This issue is due to the incorrect folder permissions (write used to be enabled for all users). This temporary fix worked for me:

  1. Rename the lab folder to something else. “W3A1” → “W3A1_old” for me.
  2. Create a new folder with the original lab name (“W3A1”). This new folder will now be owned by the user “jovyan” which fixes the issue.
  3. Use “Help” → “Get latest version” as described in the original post. The lab folder should still be owned by “jovyan”.

I had the same issue

copy this link, it will work

what I can see when you are copying the URI link, you have deleted a . from the given lab file.

I had the same issue, and follow this post, it works. hope it helps
