Could you share the public link to your notebook. From what I can see, I think tensorflow is trying to use GPU, but has python libraries for it missing. You could try submitting with just the CPU selected. Sorry, could not be of much help. ---

I have been able to solve the problem though, I created a new notebook and submitted from there apparently it worked, it seems like the main code is corrupted? ---

@Emms122 Could you describe what do you mean by created new notebook ? You just created copy of original one ? (for me it does not work) Or you created fresh notebook and copy all cells manually ? ---

@redradist . Oh I remember now. We are supposed to make a copy of the notebook first and then edit it with our answers. We submit this notebook to the grader, not the original one. Let me know if this solves the issue for you! ---

@vsnupoudel I’ve already tried to copy notebook and it do not work for me … I even created copy of the notebook on my local PC and then upload it to Coursera, but it still not working … What should I do ? How to reset the notebook ? ---

> Hi, You could refer to the first few answers here. Btw, can you confirm the notebooks exercises in Coursera environment or in Google colab environment? Above answer is for course environment. If it is colab, we do create a copy in drive, which creates a copy in our personal Google drive. We then edit this copy and upload it. ---

Hello guys, The notebook is in coursera and it passes the tests but not the grader, so there is probably some problem with updates and the grader times out. We had a similar problem sometime ago but i can’t remember what was the problem. Let me write an issue for the QA team so they can have a look at it. Thanks. ---

In the coursera environment the lab to be specific, I clicked on file then clicked on new notebook, but then I opened the link in a separate tab, and funny enough it worked after I submitted it, i hope it works for you as well. ---

Hello again! It seems the grader is timing out because of the training. Sometimes it passes, sometimes it simply times out. This wasn’t the case before. Now I am able to consistently get a grade by commenting out the `model.fit()` code block. Here are the steps I did: 1. Make sure to pass all public tests and get an accuracy \> 97%. 2. Click inside the last code cell of the notebook. 3. Select all lines in this code cell with `Ctrl+A` (Windows/Linux) or `Cmd+A` (Mac), then press `Ctrl+/` (Windows/Linux) or `Cmd+/` (Mac) to comment the entire block. It should look like this: ![commenttrain](https://global.discourse-cdn.com/dlai/original/3X/f/6/f6573eb475f4e890947e563d98db7c8fb46a6714.png) 1. From the menu bar, click `File > Save and Checkpoint`. **This is important.** 2. Once saved, click the `Submit Assignment` button. The grader should now ignore the training cell and give you a score. Please let me know if it also works for you. Hopefully it does! Thanks! ---

Hey, have u tried, opening a new notebook in a separate tab? did it show the Jupyter notebook logo at the top? instead of the coursera logo, that’s what i did for mine and it worked, though someone said “I commented out the last line of the last cell (model.eval) and it worked” you can try that ---
