Encountered error while generating package metadata

[randomrushgirl]

Initially I created an environment with python == 3.7 but the problem was that when installing the requirements, ipython==8.6.0 which requires python 3.8 or higher. This was clashing with the "Programming Language :: Python :: 3.7" in setup.py.

So I tried creating the environment with python == 3.9 (to be on the safe side) and changed "Programming Language :: Python :: 3.9" in setup.py. This results in a new problem:

Do we keep python == 3.7 and deprecate the other packages?

Additionally found this documentation that specifies removing support for Python up through 3.7 for the IPython 8.x series:

https://ipython.readthedocs.io/en/stable/whatsnew/version8.html#removing-support-for-older-python-versions

UPDATE: When running on Google Colab it works with the following versions:

python == 3.10.1
ipython == 7.31.1
