As with your previous post, you have filed this under “General Discussion”, so we don’t know which course you are talking about. As Balaji pointed out, you need to move this thread to the correct Category and Sub-Category. You can use the little “edit pencil” on the title to move it. Or you can reply here and give us the name of the Specialization and Course and I can move it for you. If we don’t now which course, then we don’t know which mentors need to be the ones to help here.

It is MLS Course 1 week 2
i have updated it
please guide me

Where you are getting this error? I didn’t see Exercise 5 in C1_W2_Linear_Regression assignment. What is the full error?

Best,
Saif.

Can you explain to me why this is happening?


I enrolled many days ago but it still does not show the modules.
what should I do?

sorry, it was maths4ML C1_W2

Hello @Somasekhar_Donthu and @Avinaba_Ghosh! As this post category is shifted from MLS to M4ML, I kindly suggest that you wait for M4ML mentors to respond to your query.

Best,
Saif.

Hello @Avinaba_Ghosh
This is the forum in which the topics related to the course will be discussed. For this problem you need to contact Coursera Help Center .

@Somasekhar_Donthu I am a mentor for Maths for machine learning. So, I imagine you are speaking about the Linear algebra course, Week 2. Now for that week there are multiple exercises. Can you please elaborate in which one are you having issues?
