numpy-groupies 0.12.3

v0.12.3

on Python PyPI

This release cuts the per-call Python overhead of the numba implementation and
adds an out= parameter for writing results into caller-provided buffers.

Faster calls

• Jitted fast-path entry: for the common case of 1-d integer indices and
  1-d data, bounds check, output-size detection, buffer allocation and the
  aggregation kernel now run inside a single compiled call — Python-level
  validation and allocation are skipped entirely on this path.
• Cheaper dispatch everywhere: all implementations resolve known function
  names through a single fused dispatch table, output dtype and fill-value
  plans are memoized across calls, and input validation relies on cheap
  attribute checks instead of the full dtype machinery.

New feature

• out=: the numba aggregate (named functions) and uaggregate accept
  an output array of matching shape and dtype and gather the result into it
  with a jitted kernel — useful to avoid allocations in hot loops.
