When I tried to enter the practice lab, it said '422 unprocessabel entity'.

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.

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.

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

Hi, I can not access labs for Deep Neural Networks with PyTorch, It is showing "500 Internal Server Error". :(

I am unable to complete my course because jupyter notebooks lab is not working from the past few days and I am getting error 502 bad gate way. Please solve this issue as soon as possible.
'' https://labs.cognitiveclass.ai/login/lti '' this url is not even processing & showing error.

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

Thanks!

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.

There is an error message:
File Load Error for PY0101EN-3-3-Functions.ipynb
Unreadable Notebook: /resources/labs/PY0101EN/PY0101EN-3-3-Functions.ipynb NotJSONError("Notebook does not appear to be JSON: 'Stack trace:\n#0 /var/www/polr/vendor/m...")

Just make the basic tool work when you click on it. For three days in a row I get "Application Not Responding"

this service is constantly giving me Service Connection Error to Jupyter server. Error dialogue popping up every few seconds. annoying
