# 或者: from numpy.lib.format import ARRAY_ALIGN [as 別名]
def test_version_2_0():
f = BytesIO()
# requires more than 2 byte for header
dt = [(("%d" % i) * 100, float) for i in range(500)]
d = np.ones(1000, dtype=dt)
format.write_array(f, d, version=(2, 0))
with warnings.catch_warnings(record=True) as w:
warnings.filterwarnings('always', '', UserWarning)

n = format.read_array(f)
assert_array_equal(d, n)
# 1.0 requested but data cannot be saved this way
