* PERF: Speed-up common case of loadtxt()ing non-hex floats. (#19598)Antony Lee2021-08-051-0/+22
| | | | | | | | | | | | | * PERF: Speed-up common case of loadtxt()ing non-hex floats. `python runtests.py --bench bench_io` reports a ~5-10% perf gain. * TST: Add tests to check fromhex not called unintentionally. Adds regression tests to check that the logic surrounding when the default floatconv applies the fromhex conversion does not change. Co-authored-by: Ross Barnowski <rossbar@berkeley.edu>

* ENH: Allow genfromtxt to unpack structured arrays (#16650)Andrew Eckart2020-09-111-1/+46
| | | | | | | | | | | | | * ENH: Allow genfromtxt to unpack structured arrays genfromtxt failed to transpose output when unpack=True and `dtype` was structured (or None). This patch resolves the issue by returning a list of arrays, as in `loadtxt`.

* TST, BUG: Re-raise MemoryError exception in test_large_zip's process (gh-16890)Antonio Larrosa2020-07-181-8/+22
| | | | | | | | | | | | Since #15893, test_large_zip's actual test is run in a child process, so when this test raises a MemoryError exception, the exception is lost and the @requires_memory decorator can't catch it to return an xfail. This commit uses a boolean variable in shared memory to flag if the exception was raised, and in that case, re-raise it in the parent process. Fixes #16889

* BUG: Fix default fallback in genfromtxtSebastian Berg2020-05-181-0/+7
| | | | | | | | | This affected (for example?) if the `dtype=object` was used without a converter, meaning that the default one is used. And this is currently the last one, which is `string_` (and thus bytes). Closes gh-16189

* DEP: Do not allow "abstract" dtype conversion/creationSebastian Berg2020-02-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | These dtypes do not really make sense as instances. We can (somewhat) reasonably define np.dtype(np.int64) as the default (machine endianess) int64. (Arguably, it is unclear that `np.array(arr_of_>f8, dtype="f")` should return arr_of_<f8, but that would be very noisy!) However, `np.integer` as equivalent to long, is not well defined. Similarly, `dtype=Decimal` may be neat to spell `dtype=object` when you intend to put Decimal objects into the array. But it is misleading, since there is no special meaning to it at this time. The biggest issue with it, is that `arr.astype(np.floating)` looks like it will let float32 or float128 pass, but it will force a float64 output! Arguably downcasting is a bug in this case. A related issue is `np.dtype("S")` and especially "S0". The dtype "S" does make sense for most or all places where `dtype=...` can be passed. However, it is conceptionally different from other dtypes, since it will not end up being attached to the array (unlike "S2" which would be). The dtype "S" really means the type number/DType class of String, and not a specific dtype instance.

* MAINT: Remove implicit inheritance from object class (#15236)Jon Dufresne2020-01-051-8/+8
| | | | | | | Inheriting from object was necessary for Python 2 compatibility to use new-style classes. In Python 3, this is unnecessary as there are no old-style classes. Dropping the object is more idiomatic Python.
* 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.
