I am unable to submit this assignment. I am taking this course via my organization. I had done this course previously in 2019. Whenever I try to submit the week 1 assignment of neural Networks and deep learning course I get shown an upgrade to submit button, clicking on it sends me to course page, after which I go back to the assignment, only to see the upgrade to submit button again.
So you can finally submit after you upgrade the assignment right?
No, that’s the thing. It keeps showing me upgrade to submit even after going through the upgrade process.
Hmm I dont know what to say, if you have performed the upgrade correctly then the next step should be to write to coursera help I guess.
