  2. Unable to "Open Tool", Start Lab Environment to open Jupyter Notebook - Databases and SQL for Data Science with Python

    I am currently unable to load the Jupyter Notebook. When I click on the "Open Tool" button for the Peer-Reviewed Assignment on week 5, it brings me to a page with "Please wait while we prepare to start your lab environment." and a loading circle. It loads for very long (might have been more than an hour) and does not come up with an error message. I have tried using different browsers, cleared my cookies, used incognito mode, and changed my internet connection. It still does not work. Please help. Thank you.

  3. banned in error

    Hello,
    I was working on the Network Labs of Unit 3 of the course "Data Visualization with Python", when it stopped running the code. After restart the kernel, and later the site, a message appeareared telling me that I've been banned for "inappropriate activity".
    As I was acting properly, I would presume that a bug, mistake or connection issue had made this happen, so I'll ask you if can fix this.
    Thank you very much, I would like to keep learning this way :)

    The message says "If you think you have been banned in error, please open a support…

  6. 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.

  9. 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.
