Transfer learning week 2,course 4 grades 0/100

All function tests are passed but grader outputs 0/100.i am submitting using a the notebook provided by the coursera work space.
Grader output: Sorry, your submission was incorrect. Please try again. [Errno 2] No such file or directory: ‘/shared/submission/submission.json’

My guess is that you have accidentally damaged some part of the notebook that the grader depends on. The next thing to try is to follow the “get a clean copy” procedure from the FAQ Thread and then very carefully “copy/paste” over just your completed code from the “YOUR CODE HERE” sections to the clean notebook. Please let us know if that fixes the problem or not.

I guess it is also possible that this was some kind of transient server error. Before you try the “get a clean copy” procedure, you could try doing this sequence and see if it helps:

Kernel -> Restart and Clear Output
Save
Submit Assignment

You can submit as many times as you like and there is no penalty. The system is smart enough to remember your best score.

Thanks a lot it worked out. I’ve reset the workspace and copy pasted my old code and got a 100/100 !
