dask 2022.01 uses a deprecated scipy API and now fails tests with
scipy 1.8.1:
_____________________________ test_one[chisquare] ______________________________
kind = 'chisquare'
@pytest.mark.parametrize(
"kind", ["chisquare", "power_divergence", "normaltest", "skewtest",
"kurtosistest"]
)
def test_one(kind):
a = np.random.random(size=30)
a_ = da.from_array(a, 3)
dask_test = getattr(dask.array.stats, kind)
scipy_test = getattr(scipy.stats, kind)
> result = dask_test(a_)

E AttributeError: scipy.stats.stats is deprecated and has no
attribute _power_div_lambda_names. Try looking in scipy.stats instead.
/usr/lib/python3/dist-packages/scipy/stats/stats.py:54: AttributeError
Likewise
test_two[chisquare-kwargs4]
test_two[power_divergence-kwargs8]
test_power_divergence_invalid
The incompatibility is fixed in dask 2022.03 (lastest is 2022.6),
