Failed in running gradient_descent.py. #6

Hello, I have installed all the Software Libraries required, and removed the header (the first line of Advertising.csv), removed the ids (the first column of Advertising.csv), and then replaced the comas by tabs (real tabs, not 2/4/8 spaces). However, I still failed in running it.

Thank you very much.

You possibly just need to create the Illustrations folder two levels above the current working directory, indicated by ../../Illustrations/ so the plots can be saved.

_FileNotFoundError: [Errno 2] No such file or directory: '../../Illustrations/gradientdescent-2.eps'
