Source: pandas
Version: 1.1.5+dfsg-2
Severity: normal
Control: affects -1 src:scipy
scipy 1.6.1 has been uploaded to experimental.
pandas fails autopkgtest with this scipy version.
e.g. see
https://ci.debian.net/data/autopkgtest/unstable/amd64/p/pandas/10621452/log.gz
The error is a discrepant dtype in TestAccessor.test_from_coo:
__________________________ TestAccessor.test_from_coo __________________________
self = <pandas.tests.arrays.sparse.test_array.TestAccessor object at
0x7fb78e8d9700>
@td.skip_if_no_scipy
def test_from_coo(self):
import scipy.sparse
row = [0, 3, 1, 0]
col = [0, 3, 1, 2]
data = [4, 5, 7, 9]
sp_array = scipy.sparse.coo_matrix((data, (row, col)))
result = pd.Series.sparse.from_coo(sp_array)
index = pd.MultiIndex.from_arrays([[0, 0, 1, 3], [0, 2, 1, 3]])
expected = pd.Series([4, 9, 7, 5], index=index, dtype="Sparse[int]")
> tm.assert_series_equal(result, expected)
E AssertionError: Attributes of Series are different
E
E Attribute "dtype" are different
E [left]: Sparse[float64, nan]
E [right]: Sparse[int64, 0]
/usr/lib/python3/dist-packages/pandas/tests/arrays/sparse/test_array.py:1196:
AssertionError
scipy 1.6.1 fixed some sparse matrix errors,
https://docs.scipy.org/doc/scipy-1.6.1/reference/release.1.6.1.html
One of the fixes affects coo dtype,
https://github.com/scipy/scipy/pull/13403
Perhaps it's triggering the pandas test failure though I'm not certain.
v1.2.2 is the latest pandas release
Has this error in test_from_coo been fixed in that latest release?
