I was having problems with the server shutting down mid program so I logged out. When I logged back in, all my work and files from the last three months were just gone! Where did they go?

The complete lab link is not accessible

Unable to access coursera notebooks...when i open it, this message comes and infinity loop continues.--> We need a bit more time than usual

Maybe update the R version for the R Kernel in the Jupyter Notebooks... Currently its running 3.5.1 which is nearly two years old and creates problems when trying to use certain packages.

I created a log in for Lab (using my LinkedIn profile) and this is different from my Coursera log in. How do i see the Coursera id in my Lab now.
How do i connect my Coursera ID to my Lab

Very interesting and invigorating exercises! However, the function Plotvec was not supported. Another possibility was that the fault was on my side.

Assalamu Aalikum.

I tried to access JupyterLab yet I received an error message which says "jupyterlab-1.labs.cognitiveclass.ai’s server IP address could not be found.".

I'm using it while practicing for a Coursera course and for some reason I get nothing expect this error message and the same goes for "zeppelin notebook" and "Rstudio IDE". How can I fix it?

Attached to this support request a screenshot for my screen while trying to access JupyterLab.

Thanks in advance.

Juppyter Lab doesn't work while Coursera charging me!

422 Unprocessable entity error shows up. Please help!

the answer is not answering this question. The correct code should be the code I written

I cannot install new packages to Rstudio IDE. the URL of CRAN is not accessible and cannot change CRAN mirror. Does anyone has the same problem?
Warning in install.packages :
unable to access index for repository http://cran.utstat.utoronto.ca/src/contrib:
cannot open URL 'http://cran.utstat.utoronto.ca/src/contrib/PACKAGES'

For Theia Cloud IDE with Docker, I cannot play with Swarm cause I cannot add worker nodes. It would be cool if I can add instances, as described here: https://github.com/IBM/intro-to-docker-lab/blob/master/lab3.md

In the exercises the dictionary created is titeled soundtrack_dic

However the questions then ask for a look up of soundtrack_dict. To avoid confusion it may be worth giving both dictionaries the same variable name
