After multiple failed attempt to pass this assignment I wanted the original ipynb file back to try afresh.
Following a stack overflow solution I deleted the .ipynb file after making a copy of it in the directory. Now I can’t open the assignment.
Now the jupyter notebook is running.
I just completed “Tweet to tensor” which is Exercise 1 and in ipynb file it’s showing “All tests passed” but when I submitted the assignment it is showing “The notebook you provided has a syntax error that prevents it from compiling.”
