Connecting to Jupyter Hub

This course contains many computer exercises. To avoid the trouble of helping all students set up a suitable computer environment, the computer exercises have been packaged in Jupyter Hub, which can be accessed through your web browser.

Here's how you connect to Jupyter Hub.

 

1. Logging in

Direct your browser to https://cloud-xx.control.lth.se, where xx is a number from 01 to 03. These correspond to one of 3 lab-computers. If you experience problems with your current computer (e.g. the computer being slow or not starting) simply choose another one.

You will be met with the following login-window. Log in using your normal LU credentials.

2. Starting your server

Start you server with the big, blue button that says it does exactly that.

3. Choosing the right lab

The computers run several labs for different parts of different courses. In the drop-down menu, choose the correct lab corresponding to the right part of this course. For exercises 1-4 and lab 1, we will run "frtn75-planning". You should not need the options under "More options". Click "start" once you found the right lab. The right drop-down menue indicates the version of the lab and should default to the latest (correct) one.

4. Opening your notebook

The actual exercises you will be doing will always be founded on notebooks corresponding to the exercise you want to be doing. On the left of the interface that just popped up you will find files and folders. The orange files are notebooks, double-click them to open them up. Other files and folders will be explained as they become relevant through the notebooks. The first time you do a computer exercise should be exercise 1, which will give you more information on how to navigate the environment.

5. Saving your work

Once you have finished working on a lab computer, we recommend you save the notebooks and code files locally. This is because if you log on to another computer the next time you work, your files will not be present. Even if you use the same computer every exercise, the files may be reset due to system updates or similar activities.

To download a file, simply right-click -> download. The next time you want to work on the files you can upload them into the environment with the upload button (right below the run-dropdown).
