Hi Jevgenijs. Thank you for the feedback. The AWS bug is still being investigated by our partners. Thank you for sharing the workaround as well from the other thread.
The submission confirmation of the Google form shows a message indicating the wait time for reactivating your account. Beyond that, learners can follow up.
As for the torch._C problem: From a few previous cases, it usually starts with an incorrect instance type or a pip install that wasn’t run. From what I know, the learners usually get through it by retrying with the correct instance type and making sure that the pip install cell (usually the first cell) is run. I see that the third topic you referenced had the same answer. I just marked it as the solution so other learners will see it. Will also add it to the FAQ.
I’m not sure about the full library requirements, but maybe I can ask the team after the holidays.
Thanks again for the feedback!
