C3_W1_Assignment... Partial grading allowed?

I usually submit my code anytime I complete a part of it: UNQ_C1, UNQ_C2, etc…

I have completed just the first task UNQ_C1 and submitted for grading:

“The notebook you provided has a syntax error that prevents it from compiling.”

Do I need to complete all the other tasks before having a feedback on UNQ_C1?

I tried different solution:

vocab_dict[unk_token]
vocab_dict[word] if word in vocab_dict else unk_ID

or

vocab_dict.get(unk_token, 0)
vocab_dict.get(word, unk_ID)

both result in: All tests passed

but when I submit for grading it always give me same error:

“The notebook you provided has a syntax error that prevents it from compiling.”

I am running out of fantasy to solve the exercise.

Better I specify:

I rebooted the server

and

Get latest version

more than once…

Simply I went on with the exercises and now it shows 60/80 score.

Unfortunately I did not note at what point the system started working again.

Pretty frustrating btw, hope you will solve it cause it is a huuuuuuge looooong exercise and having feedback on what is being requested is of great help in this case.

Btw, the exercise is overcomplicated with a miriad of syntax details and indexes issues and alignment, that as a student I would love to avoid to better focus on the central and most important ideas.

These are the kind of problems I would like to tackle in a work environment maybe for a fee.
