  2. Unable to create new cells using instructions from Lab - Jupyter Notebook - The Basics

    The instructions for Exercise 3 - Create new cells, do not seem to be valid anymore and need to be updated.
    Step 2 states From the menu, click on Insert, then Insert Cell Above or Insert Cell Below. Which menu is being referred to? There does not seem to be a menu called Insert that is visible.
    Step 3 states to use the keyboard shortcuts: [a] - Insert a Cell Above; [b] - Insert a Cell Below. Selecting a cell and pressing a or b does not seem to perform any action.

  3. IBM skills

    I keep getting the error (see attached) stating that my account is under deletion, and I have had this error for 3 months without any resolution.

    I have tried contacting support, I have message 1 every month since the error first showed, and there has been absolutely no response. The service has been appalling, no one has acknowledge messages and my assignments have been overdue because of this. The service needs to be far better, support is not good enough at all.

  16. Update conda please.

    When I install packages, I receive the following note:

    ==> WARNING: A newer version of conda exists. <==

    current version: 4.8.3

    latest version: 4.8.4

    Please update conda by running

    $ conda update -n base -c defaults conda

    Without the update, invoking the .head() method causes an error

    AttributeError: 'NoneType' object has no attribute 'items'

    However, print(df.head()) does output a header.

  18. Give students the code in .ipynb files to store locally rather than hosting them in a faulty cloud service

    IF

    1. This service is being paid for
    2. Your Jupyter Notebooks service is often down
    3. The course is paid for on a monthly basis (Time = Money)

    THEN

    You should provide the .ipynb files for student to store on their own device to complete lab sessions

    ELSE

    Respond to user queries/ Get it fixed quick

    AND

    Refund everyone for the time the service is down/intermittent.

    OR

    Provide the service at no cost.
