Problem with grading for assignment 1

finished the notebook and even though the testing passed in all functions but one
I got grading problem with get_correlation with the note:
There was a problem grading your submission. Check stderr for more details.

even though in the notebook i received:
w1_unittest.test_get_corrections(get_corrections, probs, vocab) - All tests passed

What should I do?

Hi Keren_Levi,

Apologies for the much-belated reply. Did you manage to resolve this? If not, feel free to send me your notebook attached to a direct mail and I can have a look at what’s going on.
