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?

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

Everything was working fine until yesterday(9 June 2020), Suddenly on 10 June, I lost access to jupyter notebooks on Skills Network Lab with "500 Internal Server Error". Fix this ASPA I'm losing my time.

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.

I need to use Python 3 for a Coursera lab, my JupyterLab only has Python, despite the Coursera Tutorial showing Python 3 available...

Jupyter Labs doesn't work! Coursera charges me for everyday.

My lab is using Python 2.7, how can I go about updating that to Python 3.8.2?

Thanks!

i receive many errors when i try to execute the SQL query

I keep on getting ' HTTP Error 403: Forbidden' every time i try to import a csv file into JupyterLab. This only occurred recently, I've had no problems before. This is true for chrome and explorer.

I am not able to find files (Jupyter Notebooks) under lab section on Jupyter Lab.

It says:
Cannot openCould not find path: /labs/DV0101EN/DV0101EN-1-1-1-Introduction-to-Matplotlib-and-Line-Plots-py-v2.0.ipynb

Also all the previous files are missing from labs directory.
How can I practice, if I do not get the jupyter files with exercises in it. There were other directories too, from other courses.
Please restore everything for me.

All my course material is vanished, I am not able to access the coursera course material and my jupyter notebook is also not opening up.

Despite Torchvision librairy is correctly installed (conda list show the package as 0.2.1 version), the import (ie "import torchvision.transforms as transforms") cause an error ("cannot import name 'PILLOW_VERSION'"). Tried to install a newer version of Torchvision (0.4.2) but cause another error.

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.

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

https://labs.cognitiveclass.ai/tools/jupyterlab/lab/tree/labs/DA0101EN/model-evaluation-and-refinement.ipynb

This is a example link, all the Lab in coursera cannot open, and all my old record and saves are gone..

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."
