* BUG: Histogramdd breaks on big arrays in Windows (#22561)Navpreet Singh2022-11-181-0/+11
| | | | | | | | | | | | | | | | | * BUG: Histogramdd breaks on big arrays in Windows Resolved the issue with line change from int to np.intp in numpy/numpy/lib/histograms.py * BUG: Histogramdd breaks on big arrays in Windows Resolved the issue with line change from int to np.intp in numpy/numpy/lib/histograms.py * Removed the binary files * Update test_histograms.py * Update test_histograms.py * Update test_histograms.py
* TST,MAINT: Replace most `setup` with `setup_method` (also teardown)Sebastian Berg2022-10-271-2/+2
| | | | | | | | In some cases, the replacement is clearly not what is intended, in those (where setup was called explicitly), I mostly renamed `setup` to `_setup`. The `test_ccompile_opt` is a bit confusing, so left it right now (this will probably fail)
* DEP: Remove `normed=` keyword argument from histogromsSebastian Berg2022-06-021-41/+0
| | | | | | The normed keyword argument has been deprecated for a long time. This removes it, replacing its position with the new density argument.

* MAINT: Remove implicit inheritance from object class (#15236)Jon Dufresne2020-01-051-3/+3
| | | | | | | 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.
* BUG: lib: Fix histogram problem with signed integer arrays.Warren Weckesser2019-10-151-0/+11
| | | | | | | | | | | | | | | | | | | | 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: Avoid signed overflow in histogramEric Wieser2018-08-181-0/+14
| | | | | | | | | | | | | | | | | | 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 Wieser2018-04-301-3/+26
| | | | | | | | | | | | | | | | | | | | 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

* MAINT: Remove all uses of run_module_suite.Charles Harris2018-04-061-9/+4
| | | | | That function is nose specific and has not worked since `__init__` files were added to the tests directories.
* TST: Switch to using pytest markersCharles Harris2018-04-041-1/+1
| | | | | | | | | | | Use standard pytest markers everywhere in the numpy tests. At this point there should be no nose dependency. However, nose is required to test the legacy decorators if so desired. At this point, numpy test cannot be run in the way with runtests, rather installed numpy can be tested with `pytest --pyargs numpy` as long as that is not run from the repo. Run it from the tools directory or some such.

800 self-contained lines are easily enough to go in their own file, as are the 500 lines of tests. For compatibility, the names are still available through `np.lib.function_base.histogram` and `from np.lib.function_base import *` For simplicity of imports, all of the unqualified `np.` names are now qualified
