I wrote all the code and got the same output as the correct answer, but my grade is 0. Is there a way to fix this?
The assignments I could not get the score are:
Identifying Vulnerable Communities using the U.S Census API
NYC Restaurant Inspections
Hi @ainhyeok!
I already replied on your first post, I didn’t see this was the same situation.
In any case, sometimes when you get this “Unexpected error" simply submitting the solution again can solve the problem. Have you already tried that?
Hi, I cannot solve the two problems even though I submitted again. I don’t know how to solve it
That’s annoying 
I just tried to submit one of labs you mentioned and the grader works for me. So let’s try something else: refreshing your notebooks.
You can follow the instructions here under the “Coursera Jupyter Lab Environment” section, to do so.
Hopefully this will help, but if doesn’t, let us know here so we can find a solution for this 
I could not solve the problem yet.
Hello Chris @chris.favila,
What do we know about this “unexpected error”? What should we do about it?
Cheers,
Raymond
Hi. Can you send me your notebook so we can investigate the problem? You can click my name then the blue Message button. Thanks!
I can not send you my notebook because the period of lecture was ended up yesterday. So, I have to repay again if I solve this problem T_T
Hi. Can you let us know when you purchased the course (just the month will do)?
I see. So it’s a monthly subscription. I’ll ask the team about this this coming work week. Hope that’s okay.
