N-ary Broadcasting in Sparse
09 February 2018
So far, broadcasting in Sparse has been limited to two operands. This
weekend,
I'll be working on N-ary broadcasting, which will help in implementing the three-argument version of
numpy.where.
This is one of the features needed for XArray integration (see this GitHub issue). Coming up after that:
- Arbitrary fill-values.
NaN-skipping aggregations
Update (18 Feb): It seems that N-ary broadcasting is now in a fairly stable state and will land soon. Follow the discussion over at this pull request for progress. I'm sorry for the delay compared to what I may have originally implied earlier, but this was a much more complex problem than what I had originally envisioned and I only work on this project on weekends in my free time.
