Jupyter Notebooks Introduction¶
Executing a notebook¶
The Digital Earth Australia link on your VDI desktop (described in Install step) will start Jupyter Notebooks in the dea_examples folder. Here you will find the notebooks from the User Guide below, as well as the notebook Digital Earth Australia.ipynb which provides a brief introduction to using Jupyter Notebooks.
To run a notebook follow these steps:
In the Notebook Dashboard navigate to find the notebook: clicking on its name will open it in a new browser tab.
You can run the notebook document step-by-step (one cell a time) by pressing shift + enter.
You can run the whole notebook in a single step by clicking on the menu Cell -> Run All.
To restart the kernel (i.e. the computational engine), click on the menu Kernel -> Restart. This can be useful to start over a computation from scratch (e.g. variables are deleted, open files are closed, etc…).
Closing a notebook¶
Simply closing the notebook browser tab, will not shut down its “computational engine” (called the kernel). To shut down a kernel, go to the associated notebook and click on menu File -> Close and Halt. Alternatively, the Notebook Dashboard has a tab named Running that shows all the running notebooks (i.e. kernels) and allows shutting them down (by clicking on a Shutdown button).
