* API: Make datetime64 timezone naiveStephan Hoyer2016-01-158-432/+275
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes GH3290 With apologies to mwiebe, this rips out most of the time zone parsing from the datetime64 type. I think we mostly sorted out the API design in discussions last year, but I'll be posting this to the mailing list shortly to get feedback. Old behavior: # string parsing and printing defaults to your local timezone :( >>> np.datetime64('2000-01-01T00') numpy.datetime64('2000-01-01T00:00-0800','h') New behavior: # datetime64 is parsed and printed as timezone naive >>> np.datetime64('2000-01-01T00') numpy.datetime64('2000-01-01T00','h') # you can still supply a timezone, but you get a deprecation warning >>> np.datetime64('2000-01-01T00Z') DeprecationWarning: parsing timezone aware datetimes is deprecated; this will raise an error in the future numpy.datetime64('2000-01-01T00','h')

| | | | | | | | | | | | | | | | Adds the 'order' parameter to the __new__ override in MaskedArray construction, enabling it to be enforced in methods like np.ma.core.array and np.ma.core.asarray. Closes gh-6646.

| * | BUG: fix casting rules for generic datetime64/timedelta64 unitsStephan Hoyer2015-10-132-8/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes GH6452 There are two types of datetime64/timedelta64 objects with generic times units: * NaT * unit-less timedelta64 objects Both of these should be safely castable to any more specific dtype. However, more specific dtypes should not be safely castable to generic units. Otherwise, the result of `np.datetime64('NaT')` or `np.timedelta(1)` is entirely useless, because they can't be used in any arithmetic operations or comparisons. This is a regression from NumPy 1.9, where these sort of operations worked because the default casting rules with ufuncs were less strict.

| * | | BUG/TST: Fix for #6723 including test: force fill_value.ndim==0Gerrit Holl2015-12-072-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix issue #6723. Given an exotic masked structured array, where one of the fields has a multidimensional dtype, make sure that, when accessing this field, the fill_value still makes sense. As it stands prior to this commit, the fill_value will end up being multidimensional, possibly with a shape incompatible with the mother array, which leads to broadcasting errors in methods such as .filled(). This commit uses the first element of this multidimensional fill value as the new fill value. When more than one unique value existed in fill_value, a warning is issued. Also add a test to verify that fill_value.ndim remains 0 after indexing.

I find this behavior to be very useful. It is often more intuitive than supplying a list of arguments to `transpose` and also nicely generalizes NumPy's existing axis manipulation routines, e.g., def transpose(a, order=None): if order is None: order = reversed(range(a.ndim)) return moveaxes(a, order, range(a.ndim)) def swapaxes(a, axis1, axis2): return moveaxes(a, [axis1, axis2], [axis2, axis1]) def rollaxis(a, axis, start=0): if axis < start: start -= 1 return moveaxes(a, axis, start)
