Users cannot load modules inside a JupyterLab session. If you need access to modules, please request a desktop session instead of JupyterLab. Fill out the form as you normally would for JupyterLab. After you get to a desktop, open a terminal (next to Firefox in the top bar) and type these commands:

module load gcc jupyter_conda/.2020.11-py3.8
module load ... # your modules here

This should start up Firefox shortly. If you accidentally close the window, right click on the link in the terminal and choose “open link” to restart.

An example of using LaTeX inside a JupyterLab session is shown in the screenshot below.

Note: While you can load modules in the native terminal window within JupyterLab, it only applies to the terminal tab and has no effect on the notebook tab.
