on 32bit -- Series is int64 but cut produces int32 series

[yarikoptic]

Code Sample, a copy-pastable example if possible

failing on 32bit test

    def test_single_bin(self):
        # issue 14652
        expected = Series([0, 0])

        s = Series([9., 9.])
        result = cut(s, 1, labels=False)
        tm.assert_series_equal(result, expected)

        s = Series([-9., -9.])
        result = cut(s, 1, labels=False)
        tm.assert_series_equal(result, expected)

AssertionError: Attributes are different

Attribute "dtype" are different
[left]:  int32

(Pdb) p expected
0    0
1    0
dtype: int64
(Pdb) p result
0    0
1    0
dtype: int32

1    9.0

so I guess if Series should use int64 regardless of underlying architecture default type, then cut should also produce int64, I guess.... or should Series have arch-default int??

hmm, this should always be int64. (btw this is a new tests in 0.19.2-dev)

[yarikoptic]

re new tests: yeap -- trying to build current master thus version is 0.19.1+git174-g81a2f79 to correspond to 81a2f79 (count of commits 174 is off since counted since 0.19.0, since 0.19.1 was released from the release branch, so current master is not a child of it)

[jreback]

yeah for some reason our git describe is off, not really sure why

[jreback]

normally things like this would show up on windows, but this is ok there.

[yarikoptic]

so what should we do about this one? on my end I know only asmuch as do astype in the test to workaround ;)

[jreback]

@yarikoptic if you want to debug and see where the 32bit is coming from, great. we don't test on 32-bit systems any longer.
