| * DEP: Do not allow "abstract" dtype conversion/creationSebastian Berg2020-02-063-11/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* BUG: np.load does not handle empty array with an empty descr (#15397)Sha Liu2020-01-272-8/+13
| | | | | | | The bug occurs since numpy 1.16. Before that empty descr corresponds to `np.dtype([])`. This fixes the problem by following numpy 1.15's behavior. Closes gh-15396

| | | | | | | 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.

|\ | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit c088383cb290ca064d456e89d79177a0e234cb8d and uses the same kind casting rule for the additional keyword arguments ``to_end`` and ``to_begin``. This results in slightly more leniant behaviour for integers (which can now have overflows that are hidden), but fixes an issue with the handling of NaN. Generally, this behaviour seems more conistent with what NumPy does elsewhere. The Overflow issue exists similar in many other places and should be solved by integer overflow warning machinery while the actual cast takes place. Closes gh-13103
