# Latex equations not rendered in Jupyterlab

I am using jupyter lab on my MacOS with following details;

jupyter core     : 4.6.3
jupyter-notebook : 6.1.4
qtconsole        : 4.7.7
ipython          : 7.18.1
ipykernel        : 5.3.4
jupyter client   : 6.1.7
jupyter lab      : 2.2.8
nbconvert        : 6.0.7
ipywidgets       : 7.5.1
nbformat         : 5.0.7
traitlets        : 5.0.4


As well as python version : 3.8.5.final.0 with the browser, safari version 14.0. But while using markdown mode, I tried to with mathematical equations; it is not rendering properly, please see screenshot.

I am a new user of jupyterlab and was wondering, do I need to install Mathjax separately. Because when I used to use vanilla jupyter notebook, I never encountered this issue. Help is appreciated.

Mathjax should be automatically used. Do you see any javascript errors in your browser console?

Appreciate your response. As suggested, I did look at the Javascript console, and there seems to be some error messages, please see screenshot;

I will admit honestly, I am not very sure what that message means. If possible, can you kindly help me here? Thanks

It looks like there are some problems with some custom extensions you may have installed.

If I were you, I’d follow the steps in the troubleshooting guide to try to narrow down where the problem is: https://jupyterlab.readthedocs.io/en/stable/getting_started/issue.html

Appreciate your response. Sure, I will look into it.

Hi i have the very same issue with jupyterlab 3, so i wonder if you found a solution or figured out which extension is problematic.

I’m having a similar problem. When checking my browser console I see I’m getting a ReferenceError “MathJax is not defined”. Any idea how could this be solved?
