Description
Hi there,
test_linspace
is failing for the jax backend for ivy, and hypothesis picks up two distinct failures:
AssertionError: out[0]=ivy.array(nan), but should be 9.9792015476736e+291 [linspace(9.9792015476736e+291, -1.7976931348623157e+308, 2)]
- raised on line
- Falsifying example:
linspace(9.9792015476736e+291, -1.7976931348623157e+308, num =2, dtype= 'float64', endpoint=False)
- The output for the same inputs in numpy is:
ivy.array([[ nan, -inf]])
(i.e.out[0] = nan
, the same as in jax)
AssertionError: out[0]=ivy.array(9.97920155e+291), should be ivy.array(nan) [linspace()]
- raised on line:
ph.assert_array_elements("linspace", out, expected)
- Falsifying example:
linspace(9.9792015476736e+291, -1.7976931348623157e+308, num =1, dtype= 'float64', endpoint=False)
- The output for the same inputs in numpy is:
ivy.array([[ nan]])
(i.e.out[0] = nan
, different from the jax output)
I went about fixing the second failure as jax was diverging from numpy. However, I then (locally) got:
AssertionError: out[0]=ivy.array(nan), but should be 9.9792015476736e+291 [linspace(9.9792015476736e+291, -1.7976931348623157e+308, 1)]
.
Summary: the expected value for linspace
seems to vary from the numpy value when start=9.9792015476736e+291
and stop= -1.7976931348623157e+308
(close to float64 min value) with num=1/2
, causing the test to fail for jax.
I can't reproduce these inputs for numpy test_linspace
, so it is unclear if it would also fail for numpy or any other backend - jax is the only one that has raised this issue.
