I am unable to submit assignment
the auto grader is giving
“Sorry, your submission was incorrect. Please try again. Expecting value: line 1 column 1 (char 0)”
I have checked for any unwanted print statemnent.
I have also restarted the kernal and cleared all output.
There is no specific solution for this type of problem. Please check similar threads like this one and this.
Rerun all the cells and check all the output from all the Cell blocks.
There are two common causes for issues in this assignment:
-
Sometimes this sort of issue can be caused if you are using an out-of-date version of the notebook.
-
If your notebook has a lot of output data (like spectrograms, etc), then that can clog up the grader’s processing.
Try using “Kernel → Restart & Clear Output”, then “File → Save and Checkpoint”, and then submit your work again.
