  4. `from sklearn.cross_validation import train_test_split` deprecated

    `from sklearn.cross_validation import train_test_split` is deprecated,

    it should be:

    `from sklearn.model_selection import train_test_split`

  5. Service Graph has been deprecated and replaced by Kiali

    View guestbook telemetry data -> Service Graph
    Establish port forwarding from local port 8088 to the Service Graph instance:
    kubectl -n istio-system port-forward $(kubectl -n istio-system get pod -l app=servicegraph -o jsonpath='{.items[0].metadata.name}') 8088:8088
    error: error executing jsonpath "{.items[0].metadata.name}": array index out of bounds: index 0, length 0
    Error from server (NotFound): pods "Error executing template: array index out of bounds: index 0, length 0. Printing more information for debugging the template:" not found

    As you can see above, istio-1.1.0-rc.5 does not even have Service Graph included. Please update course material.

  6. Update the training module labs with accurate content

    The labs for using DB2 Warehouse are step up for DBdash and the layout and procedure is different. The table has to be loaded and isn't the default table. I'm unable to load file and don't know the cause.

  7. Retake exam to prove you've learned from your mistakes

    Goal of exams is to test your own knowledge and understanding of an argument, so you should be able to try it again if you failed it before.
    You should be able to understand what you did wrong first time, learn from your mistakes and prove yourself you now has good knowledge of the argument.

  12. Fix the damned buttons on the quizzes!

    Apparently, your company is a "tad" slow when it comes to fixing the grayed out arrow selection buttons at the bottom of the pages. Users are complaining that this issue has affected the playform for over 2 years. Now I can't complete the quizzes. Get it together!

  14. Explain how to test URLs if using play-with-docker

    For those of us using Play-with-Docker, I think the only way to "visit" the URLs exposed by our containers is via local curl/wget? If so, I suggest adding that to the instructions. (Or if not, please enlighten us to another option.)

  15. update the course material

    Some of the commands listed in the lab is outdated and deprecated, I'd suggest review the content often and update it. Or at least put reference documentation in the course description so new learners can refer to up to date documentation. I'm available to discuss this further or help out.

  17. This question seems to have an error

    This question:

    SERVER OBJECTS (1/1 point)
    Which of the following is NOT a candidate for an object in the activities we defined for the host?

    Seems to have carried over the word "host" at the end from the prior question "Host Objects". The question probably should read:

    SERVER OBJECTS (1/1 point)
    Which of the following is NOT a candidate for an object in the activities we defined for the server?
