USING JUPYTER ON A PUBLIC PLATFORM Go to http://jupyter.org/try. Click on Try Jupyter with Python box: You will either see a directory, or a message (see below) that there are too many people using it: If that's the message - as suggested, try later! Otherwise, you will see a directory, which you use to upload/download files and work on your lab. Warning: you have no control over your files once you logout. So if you are using this public platform, and have not finished your work, download it onto your device: File > Download as > Python notebook (.ipynb) and then upload when you plan to resume working.
