  1. FIX Jupyter Labs: 500 Internal Server Error code

    https://labs.cognitiveclass.ai/login/lti_actual

    Still receiving a 500 Internal Server Error code. I would thoroughly appreciate any expedited help in the matter, as I am trying to progress through some of these labs so as to not elongate ongoing monthly payment.

  2. Session refresh + timeout

    I'd like to suggest that a "refresh" button be setup in the UI in case previous sessions data interfere with current learning. This seems to be happening when the same lab is accessed with the same credentials after a period of hours. A narrower session timeout (perhaps 3, 6, certainly less than 10 hours) would also be nice. Containers forgotten running during interrupted sessions could be draining resources.

  3. improve response times

    I've been INCORRECTLY banned 10 days ago. I've tried several times to contact you for the removal of the ban and I'm still waiting.
    10 days without studying is compromising my due dates and jeopardizing my course.
    So my suggestion is that you improve response times for this kinds of problems. I'm stuck here and can't advance any further.

  6. Jupyter notebook does not load.

    I continue to have difficulty in loading of Jupyter notebook. Today I have tried multiple times to work with my Python lab and am just frustrated.

    The link https://labs.cognitiveclass.ai/tools/jupyterlab/lab/tree/labs/PY0101EN/PY0101EN-3-3-Functions.ipynb?lti=true does not take me to Jupyter note book, neither does clicking on the Jupyter notebook icon in the left menu bar.

    I have been trying to study for last one and half hours but have only achieved waste of time.

    Please help

    You have been banned from Skills Network Labs for inappropriate activity.

    Thanks.

    Best regards,

  12. to use poly.transform() for test dataset instead instead of fit_transform()

    I notice that the polynomial model is fit and transformed on the training dataset and then fit_transform() again used on the test dataset which actually shouldn't be done since we basically shouldn't fit anything on test dataset.

  19. Regarding UI\UX on loading page on Lab Envirnment

    In this loading page

    (https://labs.cognitiveclass.ai/tools/jupyterlab/lab/tree/labs/coursera/ML010
    1EN/ML0101EN-Reg-Simple-Linear-Regression-Co2-py-v1.ipynb?lti=true)

    If you apply overflow:hidden to body tag, the non-uniformity caused in width and height which creates a feel that the page is vibrating shall be resolved.

    This may improve the UX of this page
