Drag the Terminal tab to the right side of the main work area to view both windows simultaneously. Now you have 2 tabs open: a text editor tab and a terminal tab. In the Launcher tab, click on the “Terminal” button, again to create a terminal. Now, click the “+” button in the File Browser to create a new Launcher. py, Jupyter recognizes that this is a Python file, and the text editor syntax highlights the code. Go to the File Browser tab and right-click the new text file we create and “Rename” it to hello.py. Save the file (“command+s” on Mac, “control+s” on Windows, or “File▶Save Text”). You may notice that the file has a dot instead of an “X” where you’d close it, this indicates that the file hasn’t been saved or has unsaved changes. We will not be covering JupyterLab extensions, but you can read more about them here. These customizations could pertain to themes or keyboard shortcuts, for example. Last is the Extensions Manager Tab where you can customize or enhance any part of JupyterLab. It allows you to quickly jump between sections of the document. ![]() The Table of Contents Tab is auto-populated based on the headings and subheadings used in the Markdown cells of your notebook.

Within this tab you will see the “+” button which allows you to create a new launcher. Clicking the File Browser Tab will collapse the sidebar or reopen it to this tab. The Collapsible Left Sidebar is open to the File Browser Tab at launch. They are hence isolated and independent from your Python/R/Julia instances outside of the virtual environment.Installing and Managing Python with Condaįormatted Text in the Notebook with MarkdownĪnnotations, Colorbars, and Advanced Layouts Creating the virtual environmentįirst create/choose a folder $/jlab_venv). If the workstation is outside of the campus, first connect to the VPN. The installation is made inside a python virtual environment, and this tutorial covers the installation of the following kernels: IPyKernel ( python), IRKernel ( R), IJulia ( julia), MATLAB kernel ( matlab), IOctave ( octave), stata_kernel ( stata) and sas_kernel ( sas). JupyterLab can be run on the curnagl cluster for testing purposes, only as an intermediate step in the porting of applications from regular workstations to curnagl. ![]()
