|\ \ \ \ | | | | | | | | | | | | | | | | | | | | PEP8 and pyflakes fixups for numpy/ma/*.py and numpy/ma/tests/*.py Merge cleanups prior to 1.10 release.
| * | | | BUG: Fix imports in test_io.py and test_recfunctions.py.Charles Harris2015-07-042-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Those test functions were incorrectly importing test functions from numpy/ma/testutils that were actually not defined there, but rather in numpy/testing. That did not cause an error when testutils was '*' importing all the test functions, but it was deceptive as some of the functions might appear to support masked arrays when they do not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously views of structured arrays containing objects were completely disabled. This commit adds more lenient check for whether an object-array view is allowed, and adds similar checks to getfield/setfield Fixes #2346. Fixes #3256. Fixes #2599. Fixes #3253. Fixes #3286. Fixes #5762.

| | | | | | | | | | | | | | | | | | | | 'fweights' allows integer frequencies to be specified for observation vectors, and 'aweights' provides a more general importance or probabalistic weighting.

| * | | | ENH: PyArray_FromInterface checks descr if typestr is np.voidjaimefrio2015-03-081-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the 'typestr' member of the __array_interface__ dictionary defines a np.void dtype, check the 'descr' member, and if it is a valid dtype description and it is not the default one, use it to construct the dtype for the array to return. This fixes #5081, as as_strided no longer has to worry about changing the dtype of the return.
* | | | | BUG: loadtxt fails with complex data in Python 3.Charles Harris2015-03-111-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that the Python complex type constructor only accepts a pair of numbers or a string, unlike other numeric types it does not work with byte strings. The numpy error is subtle, as loadtxt opens the file in the default text mode, but then converts the input lines to byte strings when they are split into separate values. The fix here is to convert the values back to strings in the complex converter. Closes #5655.

* | | | | BUG: enable working around pickle compatibility issues on Py3 in npy filesPauli Virtanen2015-03-085-1/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add pickle compatibility flags to numpy.save and numpy.load. Allow only combinations that cannot corrupt binary data in Numpy arrays. Use the same default values as Python pickle.
* | | | | BUG: genfromtxt gave OverflorError for large integersThomas Robitaille2015-03-062-4/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix StringConverter to avoid OverflowError in genfromtxt. Before, int(2**66) would work (and return a ‘long’) but then np.array([2**66], dtype=np.integer) would not work and return an OverflowError which would propagate to genfromtxt. This commit fixes this by ensuring testing in advance whether an OverflowError will occur. In addition, this adds an explicit np.int64 entry on systems where integer means int32. Values larger than 2**63-1 will be cast as float. This includes a regression test and adds an entry to the release notes.

|/ / / | | | | | | | | | | | | | | | | | | | | | Per the mailing list discussion [1], I have implemented a new function `broadcast_to` that broadcasts an array to a given shape according to numpy's broadcasting rules. [1] http://mail.scipy.org/pipermail/numpy-discussion/2014-December/071796.html
* | | MAINT: Fix pmt test in numpy/lib/tests/test_financial.py.Charles Harris2015-02-171-24/+22
| | | | | | | | | | | | | | | | | | | | | The tests were using assert_almost_equal and setting the precision to 3 decimals. The reason for that low precision appears to have been the failure of the tests for a more reasonable precision. The fix was to use assert_allclose instead.
* | | BUG: Fix zero divide warning in financial.pmt.Fei Liu2015-02-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | The pmt function in financial.py does a zero divide when rate=0 because error because the alternatives in np.where() are evaluated befor the selection is made.first before going into the function however, the denominator can be zero at that time. Closes #4701.

|\ \ | | | | | | BUG: Fix genfromtext NameValidator arguments passed to easy_dtype.
| * | MAINT: Make argument determination in NameValidator more precise.Charles Harris2015-01-231-1/+5
| | | | | | | | | | | | | | | | | | | | | The function was useing `'u' in case_sensitive` to detect `upper`. Make that more precise with `case_sensitive.startswith('u'). Raise ValueError if case_sensitive has unrecognized value.
| * | TST: Fix bug in test_dtype_with_converters_and_usecols.Charles Harris2015-01-231-2/+2
| | | | | | | | | | | | | | | | | | | | | The case_sensitive argument to np.recfromcsv has a default value of 'lower'. That value was not previously correctly passed on, but is now, so the previous expected values in this test were incorrectly upper cased.
| * | BUG: Fix genfromtext NameValidator arguments passed to easy_dtype.Alan Briolat2015-01-231-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | np.genfromtxt validates field names twice: once in genfromtxt and once in easy_dtype. Whilst the arguments to genfromtxt are used in the first validation, they aren't passed to easy_dtype (which is used only when dtype != None) and therefore in this case the default validation (strip non-alphanum, replace spaces) gets confusingly applied, ignoring genfromtxt's arguments. This patch adds fixes genfromtxt by passing the appropriate arguments onwards to easy_dtype. That is probably the least invasive way to fix the issue.

* | | ENH:Add keyword nrows to genfromtxt.styr2015-01-231-0/+26
|/ / | | | | | | | | | | | | | | | | | | This allows one to specify the maximum number of row processed in in a call. The new functionality allows for reading more complex data formats. For instance, multiple calls can be used to read in multiple arrays stored in a single file. Closes #5084. Closes #5093.

|/ / | | | | | | | | | | | | | | | | | | | | This PR adds an implementation of `nanprod`. The actual function is a two-liner adapted from `nansum`. Most of this PR consists of documentation and tests (for which I took the opportunity to do some consolidation). A method with the same functionality exists in pandas, and I was surprised to discover that it's not in numpy.
