unable to "share on github" from jupyter, github returns a "404 not found page" so you're using an old OAUTH link - please fix this, this was working before

I am unable to open the datasets in this link.

I need to be able to download the datasets in these links but it gives an error.

Unable to open Skills Network Labs. I get the following error message. I've tried logging off and reloading the site several times but with no luck. I get the following error message: 500 Internal Server Error Cici Mud Sorry, something went wrong. Please try again. If this does not work please open a support ticket.

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.

Hi there,

After clicking JupyterLab link.
Starting Docker Container message is displayed. And then Blank screen is displayed. PSA

Please guide to start JupyterLab and start using Jupyter Notebooks.

Thanks in advance.

I obtained an API key and URL for the lab. I am getting these errors:

Since this morning, I was not able to open any of the lab notebook for the Python for Data Science and AI course on Coursera.

I'm unable to start lab from edx and getting the error page.
Attached is the page for reference.

I am not able to see any lab exercises in the lab. Instead there is an ERROR.md file existing in my lab. The error message shows "If you're seeing this file, it's because we weren't able to find your real files. Please contact support using the tab on the side of the screen."

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.

i am doing a Python for Data Science course on edX and cannot open one of the notebooks as I keep getting "File "PY0101EN-1.3notebookquizzStringOperations.ipynb" has unsaved changes, close without saving?"

no matter if I press OK or Cancel, i still cannot open it and continue with my study. I have tried clearing cache and rebooting the machine. Tried closing unsaved and re-opening, still says i have an unsaved notebook that i am trying to close. Stuck here, any ideas?

Hi,
Since yesterday after running a few commands I am getting 502 bad gateway error again & again and not able to connect to the jupyterLab now. Stuck with my project, please suggest....!!

Coursera course assignments to Skills Network Labs are not opening. It says path not found - Could not find path: /labs/DV0101EN/DV0101EN-2-3-1-Pie-Charts-Box-Plots-Scatter-Plots-and-Bubble-Plots-py-v2.0.ipynb

I'm getting this error for almost a month now. Donno why IBM and Coursera sponsor such courses.
Screenshot of error is also attached. Pls resolve this issue at the earliest.

I'm unable to open Jupyter notebook. I keep getting this page and it never opens.

I would like to open a discussion about the working materials in the Jupyter Notebook labs. About the quality, the positive or negative remarks. Also, about some parts that are a bit unexplained or can be done differently. In other words, my idea is to post some feedbacks about the Jupyter Notebook labs.
