Ever after successfully passing all tests,I’m receiving 0% grades & it is showing - Cell #UNQ_C1. Can’t compile the student’s code. Error: OSError(‘data/ex1data1.txt not found.’)

Kindly helphttps://www.coursera.org/learn/machine-learning/programming/jsE7w/week-2-practice-lab-linear-regression/lab?path=%2Fnotebooks%2FC1_W2_Linear_Regression.ipynb

This error means that a file you are supposed to read from during the assignment has not been, check if it is in the directories and if not try to reset the notebook assignment (because you might have deleted it or changed its name) and if even after that it is not found, try to find it online and upload it yourself.

It is provided in the lab workbook. In Jupiter notebook environment. In I try to download it & then give the absolute path Like ‘C:\user\download\path’ it is not even loading in the notebook. Kindly guide.
