cell_to_child_pos() version 4 of the Python API client about h3 HOT 3 OPEN

Unfortunately that function was introduced in version 4.1.0 and I do not believe a new Python binding version has been released since that. When the Python bindings are updated that function should be included, as it is part of the H3 API.

Thank you for the quick response. Couple of follow-ups:

• Is there an anticipated release date for 4.1.0 Python bindings?
• cell_to_local_ij() is available with 4.0.x but I'm not understanding the output. Can you point me to more documentation than what's here?

You can see some discussion of the coordinates here, but we don't have more docs that I know of. Essentially cell_to_local_ij gives you 2d axial coordinates you can use to traverse cells in a limited, local space (generally speaking, on the same or adjacent faces of the icosahedron). This is an advanced feature, and in general better avoided because of the limitations in the coordinate system it returns, but it can be very useful in some cases, e.g. applying ML or computer vision algorithms that require 2d matrix input.
