For some reason changes a causing a new failure in array API test suite:

array_api_tests/test_creation_functions.py ........F..... [ 3%]

This failure is not present in the main branch.

I saw this too. It's in linspace. It doesn't seem to be related to this PR, but worth looking at.

Yes, the "test_creation_functions.py" failure is sporadic, I just reran the workflow steps and this particular test passed.

[oleksandr-pavlyk]

I just reproduced the failure locally:

E           hypothesis.errors.Flaky: Hypothesis test_linspace(num=3866, dtype=dtype('float32'), endpoint=False, data=data(...)) produces unreliable results: Falsified on the first call but did not on a subsequent one
E           Falsifying example: test_linspace(
E               num=3866,
E               dtype=dtype('float32'),
E               endpoint=False,
E               data=data(...),
E           )
E           Draw 1 (start): 9.999999747378752e-06
E           Draw 2 (stop): -2.220446049250313e-16
E           Draw 3 (kw): {'dtype': dtype('float32'), 'endpoint': False}
E           Failed to reproduce exception. Expected:
E           >   ???

with the underlying cause being the following failure in "_copy_from_numpy_into(dst, np_ary)":

E           >       ti._copy_numpy_ndarray_into_usm_ndarray(
E                       src=src_ary, dst=dst, sycl_queue=copy_q
E                   )
E           E       RuntimeError: Native API failed. Native API returns: -30 (PI_ERROR_INVALID_VALUE) -30 (PI_ERROR_INVALID_VALUE)
