Grader ran out of memory

When I submit I get the following error:
Learner Error: Grader ran out of memory

I can’t scroll on this forum and find whoever has faced this similar issue.
Anyone knows how to overcome this ?

hi, @Sara_NA!

Please refer to this thread - one potential reason for the problem is the lack of compute resources during busy hours. However, I’ve found some threads where the issue was caused by an incorrect (too large) model architecture. But first please try submitting again during off-peak hours.
Let me know if this helps.

Dear @Dmitriy_Khvan
I tried again during the morning and it worked out.
Many thanks for your quick and prompt help!

Kind regards,
