C1 W1 Lab3 cost function unable to view plots

Hi everyone, I am completely new to coding. Need help. I can’t see the plots in Lab 3. All I did was click on the Open Lab tab, but the plots were not shown.

Can someone please guide me through this? Thanks

Best regards,
Chyn Hwa

You need to click on the “Run” button (in the top menu) for every cell in the notebook, starting from the top. This runs the code in that cell.

You have to do this every time you open a notebook.

Note that you will not be able to succeed in this course without at least some basic Python programming skills.

I recommend you attend a Python tutorial, then come back to this course.

Thank you so much for your kind reply and recommendation. I shall take up Python for beginner course now. May I know whether the following course structure good sufficient as a prerequisite for this course? Appreciate it if you can pinpoint any specific courses on Coursera that will benefit me before I return to this course.

That’s a lot more than you need. You just need a basic Python tutorial, not a full expert specialization.

You should be able to find one for free online that you can complete in a few hours.

Great! Thank you for your valuable suggestion.
