How to enable MathJax in Jupyter 4 again

[Dietmar Winkler]

Hi,

I've noticed that since upgrading from ipython notebook 3.2.1 to jupyter 4 the LaTeX in my notebooks and the output of sympy is no longer rendered using MathJax.

Looking at the source I notice that in 3.2.1 this line was included:

<script type="text/javascript" src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML-full,Safe&delayStartupUntil=configured" charset="utf-8"></script>

which now in 4 has become:

<script type="text/javascript" src="/static/components/MathJax/MathJax.js?config=TeX-AMS_HTML-full&delayStartupUntil=configured" charset="utf-8"></script>

So that means one needs to have MathJax locally installed in order to use it. Is there anywhere a configuration setting to make Jupyter use the cdn again instead?

Thanks,
Dietmar

So it turns out (after a long search and trial and error session) it was a Firefox problem only on my side (but might just as well have been Chromeium or any other browser) because it was the evil cookies that did this. I had at some point in the past played around with MML rendering and that was stuck in a cookie.

Solution: Clear the cookie.

One can also test this quite easy by using the private mode just to see if MathJax then loads.

Thanks to @jasongrout on gitter for his patience and help.

I encountered the same problem. 

However cleaning the coockie does not work...

Clearing cookie doesn't help. 

Notebook server log in CLI gives this: 404 GET /static/components/MathJax/extensions/TeX/mhchem.js?rev=2.5.3 (127.0.0.1) 8.81ms referer=http://localhost:8888/notebooks/gdriveinsync/my_notebook.ipnb.

Any thoughts?

If you are using anaconda then there is/was a problem with the MathJax version installed. If you download mathjax and replace <anaconda path>/lib/python2.7/site-packages/notebook/static/components/MathJax with downloaded version all the errors should disappear. Well at least they did disappear for me.

Cheers,
Kris

I also had the problem. The folder /usr/local/lib//python2.7/dist-packages/notebook/static/components/MathJax/

extensions/TeX didn't exist at all. I replaced the existing MathJax folder by a https://github.com/mathjax/MathJax clone, after that everything worked as before (only the font seems slightly different to me).

@nilqed how did you install the notebook?

Well, on Ubuntu 14.04 I did: sudo pip install -U jupyter
Before that I had IPython 3.0dev.

Actually the MathJax folder was there, only the TeX extensions were lacking ... so all '\def ...' ignored.

Thanks! Cloning MathJax works.
