Seems like a platform error to me.
Please check notebook metadata and refresh the workspace if required / in doubt.
If that doesn’t help, please click my name and message your notebook as an attachment.
I submitted your code to the grader more than 20 minutes ago. It’s probably going to timeout.
Please keep in mind that this assignment will run pretty fast if you code the functions properly.
- There’s no need for an extra list in
parse_data_from_file. The field in the sentence index withinrowis already a string. An extra for loop makes your implementation really slow. - See this on
remove_stopwords.
It would help if you picked a python course since this specialization doesn’t cover it. Happy learning.
