C1W2_Assignment: equations and formulas are not rendered correctly in the notebook

In the Jupyter notebook of <Programming Assignment - Gaussian Elimination>, all the equations and formulas are rendered as their raw markup language for example:

$$ \begin{align*} 2x_1 + 3x_2 + 5x_3&= 12 \ -3x_1 - 2x_2 + 4x_3 &= -2 \ x_1 + x_2 - 2x_3 &= 8 \

\end{align*} $$ 

And the [ and ]s around matrixes are shown as an empty square.

Maybe it’s caused by failures in loading some resources, since I found error messages in the browser’s inspection console like this:

stats.pusher.com/timeline/v2/jsonp/1?session=MjYzNjE2...
       Failed to load resource: net::ERR_CONNECTION_REFUSED
/api/userPreferences.v1/83953048~HONORS:1 
        
        
       Failed to load resource: the server responded with a status of 404 ()

I use Chrome as the browser and I just updated it today. How to fix this?

Thanks.

Yes, it sounds like you have some browser issues. The rendering of LaTeX is handled by the MathJax plugin. Do you have that installed and activated?

Also 404 errors may indicate that some security software between your browser and the website is causing problems. It could be A/V software on your computer or proxy servers or firewalls between your computer and AWS.

I tried to switch to using Safari to open the Jupyter Notebook and this fixed the rendering issues for the matrixes, there still exists some raw Latex code but I think they won’t affect my understanding of the main content of the assignment.

And yes I am using VPN service and I also tried to switch lines, so now the majority of the issues are also solved in Chrome.

So I think now I can proceed with the assignment.

Thanks for your reply @paulinpaloalto :slight_smile:
