API: Make MaskedArray.mask return a view, rather than the underlying mask
|
| | |
| |
| |
| |
| |
| |
| |
| | |
This prevents consumers from reshaping the mask in place, which breaks things
As a result, `x.mask is x.mask` returns `False`, but this was already true of `x.data is x.data`.

The pickle module was being imported from numpy.core.numeric. It was
defined there in order to use pickle5 when available in Python3 and
cpickle in Python2. The numpy.compat module seems a better place for
that.

BUG: Make `arr.ctypes.data` hold onto a reference to the underlying array
|
| | |
| |
| |
| |
| |
| |
| |
| | |
We do this by going through ctypes.from_buffer, which keeps the object the buffer came from alive.
A bunch of hacks are required to produce a sufficiently simple buffer for ctypes to accept.

* ported the refguide_check module from SciPy for usage
in NumPy docstring execution/ verification; added the
refguide_check run to Azure Mac OS CI
* adjusted NumPy docstrings such that refguide_check passes

This should give an empty result, not an error. The problem
was that the empty list was interpreted as a list of strings.

Cover the string and numeric types. Structured types were
already covered.
|
| |
|
|
|
|
|

The type of the fill_value needs to be `bool_` in order to match
the result type of `==` and `!=`.
Closes #12248.

Fixes the regression introduced by #10211 where the masked array fill
value type was not properly converted by astype.

All imports of pickle from numpy modules are now done this way:
>>> from numpy.core.numeric import pickle
Also, some loops on protocol numbers are added over pickle tests that
were not caught from #12090
|
| |
|
|
|
| |
This was used internally only by a private function that is also unused.
The loop adding type aliases was shown by #12007 to have no effect.

After the pytest migration, test classes no longer inherit
from unittest.TestCase and and the fail method does not
exist anymore.
In all these cases, we can use assert_raises and assert_raises_regex instead

The TestMaskedArrayMethods.test_sort_flexible test was failing for for
the subarray checks on big endian systems. That was probably due to
subarrays being sorted as bytestrings. This fixes the test by simply
checking that the sort does not error rather than checking the result.
Closes #11716.

unnecessary import dependencies
pytesttester is used by every single subpackage, so making it depend on np.testing just creates cyclic dependencies that can lead to circular imports
Relates to #11457

Eliminates all mentions of `np.where(cond)`, instead pointing the reader to np.nonzero.
Also changes some example numbers to avoid collisions, making them easier to follow.
Some minor doc improvements for np.ma.where too.

BUG: Ensure __array_finalize__ cannot back-mangle shape

Since dtype and shape are properties, this needs a somewhat

Further progress in isolating matrix in preparation of its
deprecation. There is one place left with an explicit reference
to matrix (in MaskedArray.count), which is to be solved later.

That function is nose specific and has not worked since `__init__` files
were added to the tests directories.

Numpy can now be tested using the standard
`python -c"import numpy; numpy.test()"`
construct.
