LLM stops working after a while with a useless error message

Hello and thank you for the course and especially for the opportunity to use the LLM in the Lab. However, when I use the LLM, it only answers up to 8 of my questions and then stops working, giving no answers at all. On top of the screen there appears an indicator that an error has happened, but it does not contain any text, looking like this:

Maybe I have exceeded my usage quota for the LLM, but if so, it would be very helpful if the error message told me this and when I can use the LLM again. In any case, a detailed error message would be nice! Even better if I could continue using the LLM, depending ou your usage policy.

Thanks! Lene

I am also seeing this. It has plagued me on every assignment so far, but I have overcome it by relaunching. However, now, even after relaunch, I cannot send even one prompt.

I have said this in another thread, but I lost hours with battle of this course’s linked chat prompt. I used ChatGPT.com (it is free for small usage, and you get new credits every 3 hours) and passed with course’s information even the larger Traveling Salesman Problem.

I faced the same issue. It’s quite frustrating because you have to start the chat from scratch in a new thread and all context is lost. It’s a limit on the tokens, I believe, because I have had it stop working even after a single reply where my context was huge.

@chris.favila, is this something you can investigate?

Adding @lucas.coutinho here. Thanks.

Hi,

We’ve seen other learners with this issue as well, we have escalated it to Coursera. As soon as we have a return I let you all know.

Sorry for the inconvenience.

Best,
Lucas

I appreciate you sharing this tip. I am going to try this out.

This is still a constant issue for me.
