* BUG: accept zeros on numpy.random dirichlet function (#23440)Paulo Almeida2023-04-111-0/+4
| | | | | Changed alpha value error to pass a null value. This way, dirichlet function (on the generator, not mtrand) won't raise a value exception at 0. Also added test.
* TST: Skip tests that are not currently supported in wasmHood Chatham2022-11-111-1/+2

* TST,MAINT: Replace most `setup` with `setup_method` (also teardown)Sebastian Berg2022-10-271-5/+5
| | | | | | | | 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)
* BUG: Fix boundschecking for `random.logseries`Sebastian Berg2022-10-181-5/+14
| | | | | | | | Logseries previously did not enforce bounds to be strictly exclusive for the upper bound, where it leads to incorrect behavior. The NOT_NAN check is removed, since it was never used: The current bounded version always excludes NaNs.
* ENH: Add the capability to swap the singleton bit generatorKevin Sheppard2022-08-111-0/+67
| | | | | | | Add a new version or seed that supports seeding any bit gen Add set/get_bit_generator as explicity methodds to support swapping closes #21808
* TST: Fix spellingKevin Sheppard2022-07-191-1/+1
|
* BUG/ENH: ALlow bit generators to supply their own ctorKevin Sheppard2022-07-191-0/+18
| | | | | | | Allow bit generators to supply their own constructors to enable Generator objects using arbitrary bit generators to be supported closes #22012
* Port error to RandomStateKevin Sheppard2021-02-261-0/+8
|
* BUG: Prevent RandomState from changingKevin Sheppard2021-02-261-0/+9
| | | | | | | | Apply vonmises fix only to Generator Add tests for correctness closes #17378 closes #17275
* BUG: shuffling empty array with axis=1 was brokenRalf Gommers2021-01-231-1/+5
| | | | | | | | | | | | | This would trigger: ``` NotImplementedError: Axis argument is only supported on ndarray objects ``` because empty arrays and array scalars would take the "untyped" path. The bug exists only for Generator, not in RandomState (it doesn't have axis keyword for `shuffle`), but update both because it keeps implementations in sync and the change results in more understandable code also for RandomState.
* TST: Make test suite work in FIPS (140-2) ModeNikola Forró2020-10-291-32/+32
| | | | | | | | | Tests using MD5 algorithms fail in FIPS Mode because MD5 is not FIPS compliant. Replace MD5 with SHA256 to overcome that. Signed-off-by: Nikola Forró <nforro@redhat.com>
* BUG: Validate output size in bin- and multinomialKevin Sheppard2020-07-141-0/+10
| | | | | | Check that size is not being broadcast closes #16833
* TST: random: Skip a test if integers are 32 bit.Warren Weckesser2020-04-271-0/+2
|
* TST: random: Add more repeatability tests for random integers.Warren Weckesser2020-04-271-0/+22
| | | | | | | Add repeatability tests for when the range of the integers is `2**32` (and `2**32 +/- 1` for good measure) with broadcasting. The underlying functions called by Generator.integers and random.randint when the inputs are broadcast are different than when the inputs are scalars.
* MAINT: Remove implicit inheritance from object class (#15236)Jon Dufresne2020-01-051-9/+9
| | | | | | | 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 uses of scalar aliasesEric Wieser2019-11-131-3/+3

* BUG: Fix segfault in `random.permutation(x)` when x is a string. (#14241)Maxwell Aladago2019-08-221-0/+15
| | | | | | | | | | | | | | | | | | | | | | * fixing segfault error in np.random.permutation(x) where x is str * removed whitespace * changing error type to ValueError * changing error type to ValueError * changing error type to ValueError * tests * changed error to IndexError for backward compatibility with numpy 1.16 * fixes numpy.randomstate.permutation segfault too * Rolled back to ValueError for Generator.permutation() for all 0-dimensional * fixes refuige erro and rolls backs to AxisError
