The dependency information of the Python package needs to be updated

[penguin-wwy]

#460 added a dependency on urllib3>=2.0.7, but this version of urllib3 no longer supports Python 3.6 (https://github.com/urllib3/urllib3/blob/2.0.7/pyproject.toml). However, since the setup.py was not updated accordingly, Python 3.6 will still attempt to install versions after PR 245, resulting in the following error.
