* 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: lib: Fix histogram problem with signed integer arrays.Warren Weckesser2019-10-151-5/+15
| | | | | | | | | | | | | | | | | | | | An input such as np.histogram(np.array([-2, 0, 127], dtype=np.int8), bins="auto") would raise the exception ValueError: Number of samples, -1, must be non-negative. The problem was that the peak-to-peak value for the input array was computed with the `ptp` method, which returned negative values for signed integer arrays when the actual value was more than the maximum signed value of the array's data type. The fix is to use a peak-to-peak function that returns an unsigned value for signed integer arrays. Closes gh-14379.

* BUG: Increment stacklevel for warnings to account for NEP-18 overrides (#13589)Stephan Hoyer2019-05-201-5/+6
| | | | | | | | | | | | | | * Increment stacklevel for warnings to account for NEP-18 overrides For NumPy functions that make use of `__array_function__`, the appropriate the stack level for warnings should generally be increased by 1 to account for the override function defined in numpy.core.overrides.

* ENH: set correct __module__ for objects in numpy's public APIStephan Hoyer2018-11-131-1/+5
| | | | | | | | | | | | | Fixes GH-12271 Tests verify that everything in ``dir(numpy)`` either has ``__module__`` set to ``'numpy'``, or appears in an explicit whitelist of undocumented functions and exported bulitins. These should eventually be documented or removed. I also identified a handful of functions for which I had accidentally not setup dispatch for with ``__array_function__`` before, because they were listed under "ndarray methods" in ``_add_newdocs.py``. I guess that should be a lesson in trusting code comments :).

| * BUG: Avoid signed overflow in histogramEric Wieser2018-08-181-3/+29
| | | | | | | | | | | | | | | | | | When dividing the range between first and last, the formula `(x - first) / (last - first)` is used, where `last >= first` This falls apart if the types of these variables are signed integers, in which case overflow can occur. The solution is to force the subtraction result to be unsigned. This is a regression in 1.15.0

* ENH: Disable fuzzing on histogram boundariesEric Wieser2018-04-301-21/+8
| | | | | | | | | | Previously a fuzzy rounded comparison was used for the rightmost bin of histogramdd. It's not clear why this was done, and it resulted in surprising behavior. This also removes the restriction that bin edges must be floats, and allows integer arrays to be passed (and returned) Fixes gh-10864
