* ENH: unstructured_to_structured converts dtype argument (#22442)LeonaTaric2022-10-191-0/+2
| | | | | | | | | | | | Before: >>> field = unstructured_to_structured(np.zeros((20, 2)), dtype=[('x', float), ('y', float)]) # failed >>> field = unstructured_to_structured(np.zeros((20, 2)), dtype=np.dtype([('x', float), ('y', float)])) # success After: >>> field = unstructured_to_structured(np.zeros((20, 2)), dtype=[('x', float), ('y', float)]) # success >>> field = unstructured_to_structured(np.zeros((20, 2)), dtype=np.dtype([('x', float), ('y', float)])) # success Closes gh-22428

| | | | | | * if you believe the comments that this warning suppression should be safe to remove after `1.16`, then it should be safe to remove now?

* MAINT: Remove unnecessary 'from __future__ import ...' statementsJon Dufresne2020-01-031-2/+0
| | | | | As numpy is Python 3 only, these import statements are now unnecessary and don't alter runtime behavior.

| | * BUG: Always return views from structured_to_unstructured when possibleEric Wieser2019-05-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Also applies to unstructured_to_structured While producing correct resutls, the test added in this commit would previously make an unecessary copy, causing the assertion to fail. The cause was `astype` was being asked to convert from a subarray of shape `(x, y)` to one of `(x*y,)`, which it cannot do without making a copy. This changes the approach used to skip the step of flattening subarrays to 1d

| * | BUG: Fix structured_to_unstructured on single-field typesEric Wieser2019-04-151-1/+1

* | MAINT: Fix remaining misuses of bool(dt.names)Eric Wieser2019-08-191-3/+3
| | | | | | | | It's not clear that these have any visible effect, but we should be consistent with how we detect structured types.

* | BUG: recfunctions: Don't return None in place of empty sequencesEric Wieser2019-08-191-6/+6
|/ | | | | | Replacing empty tuples with `None` is a bad idea, and just results in an API that is hard to consume - especially since the behavior was never documented. This affects `get_names`, `get_names_flat`, and `get_fieldstructure`.

* BUG: recfunctions.join_by fails when key is a subdtypeEric Wieser2017-07-011-11/+47
| | | | | | | | | It seems that working with .descr is a generally terrible idea. Instead we introduce `get_fieldspec`, which returns a list of 2-tuples, encapsulating subdtypes. This also means that np.core.test_rational.rational survives a roundtrip - its .descr is 'V8', which ddoesn't survive
