I am a beginner. Please help. When I pass the jupyter lab command the following error occurs:-

Please help!!! I am unable to use Jupyter Lab anymore and it is extremly problematic for me!
Thank You.
From my point of view, it may be faster, and easier is to reinstall Jupyter Lab (maybe create a new conda environment if needed).
One more thing, you might consider backing up your conda environment when everything is smooth:

That version of the scrapinghub package is evidently not compatible with Python 3.10.
Downgrade to Python 3.9, or upgrade the package to a new, compatible version if there is one which there may not be yet: https://github.com/scrapinghub/python-scrapinghub/issues/160
I created a new virtual environment, and installed a package (particularly, cvxpy). I ran some tests and it worked fine. Then, for no apparent reason, I started getting errors when running pip:

It says there is a circular import in pip itself - how can this be?
I tried to remove the virtual environment and re-install everything, but after some time, it happened again. How can I debug this strange circular import, in pip itself?

This is an Anaconda 3 installation on Windows. How can I get this to work correctly?
When I tried to install discord.py, I saw an error. When I simply enter the pip command, I see this error again . I tried other pip commands, result was same. I reinstalled python but it did not help.
