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 anaconda
module load ... # your modules here
jupyter-lab

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.
