ImportError: cannot import name 'Self' from 'typing'

[zhuoqun-chen]

typing.Self is included in python 3.11 and later, thus the import part in the examples, such as steering, should add additional check, for example,

try:
    from typing import Self, Sequence
except:
    from typing_extensions import Self, Sequence

to be backward compatible. Or you can update the doc and remind users that examples require 3.11 or later.

Oh, thanks for pointing this out, @zhuoqun-chen!

We usually use RoSys with Python 3.11, but according to pyproject.toml we allow for Python 3.10 as well.

@rodja What do you think: Should we keep supporting Python 3.10? We'd probably only need to add 3.10 to the pytest workflow and fix some minor issues like importing Self.
