The notebook crashes while (or shortly after) loading ‘model.pkl.gz’. This is immediately before UNQ 9.
When I submit the assignment, my UNQ_9 passes the grader (so - yay! passed the assignment), but the results for UNQ 10 are “There was a problem grading your submission. Check stderr for more details.”
What should I do?
This probably means you are not doing something right which is crashing the grader. Let me DM regarding this.
The model can take a long time to load. Unfortunately, the reason for this is not completely clear. Have a look at this thread. You could try loading the model, take a break of around 15 minutes, and see whether it has succesfully loaded. Alternatively, you can just go head with week 3.
Sorry about that, I wish I could help you to truly resolve this issue.
Hi @reinoudbosch ,
The problem isn’t that the model is taking so long to load. It’s that my webpage crashes before (or shortly after) it finishes.
I’ve never been able to test UNQ 9 or 10 for myself. The grader passes UNQ 9, so I figure it’s OK. My lab ID is ukqkbtnulctn. Is there a chance you could look at my UNQ 10 & let me know if there’s any sort of obvious slip-up/lack of understanding, or if this is just tied up with the model problem?
Unfortunately I cannot access your assignment through your lab ID. I would suggest you wait for @Mubsi to DM you. If there should be an issue unrelated to your code, he will be the best person to help you.
As @reinoudbosch, this is unpredictable behaviour and are unable to clearly figure out what causes it. I was able to run your assignment, even after successfully loading the model, the assignment sort of became unresponsive (I have seen this behaviour many times before with this assignment) and I too couldn’t get to UNQ C9 & 10.
As you mentioned, if you submit your assignment, you are able to pass till UNQ C9. I have fixed your mistake in UNQ C10, so you should be able to pass that as well now. Let me know if you are unable to.
I apologise for the inconvenience you have faced. I have taken a note of this and will try to improve this experience for you and others.
Hi @Mubsi ,
Thanks. I suppose that’ll teach me to read the instructions more carefully…
In my case, the loading process never ends.
@Mubsi I have a similar issue. The web page seems to crash when loading the pre-trained model. The grader returns: “There was a problem grading your submission. Check stderr for more details.” What shall I do? I do not see any issues so far and no error log is thrown. At this time, the submission was marked with 80/100 not passed.
I’ve tried it multiple times. So the issue lays in the loading the pre-trained weights from the file system. This in fact probably causes the issue for the grader.
Can you share the output of your grader ? Particularly of the exercises. I want to see which ones you have passed and which ones you failed.
Please tag me when you reply.
Hi @Mubsi ,
I got it to work Passed all of them now. The issue in the notebook did not affect the grader. Thanks for your fast response on that.
Glad to hear that. In that case, I think it is possible that something changed in your notebook which shouldn’t have had.
