The following code should raise a ComputeFollowsDataInferenceError, however such an exception is not raised:
import dpnp
import dpctl
import numba_dpex as dpex
from numba_dpex.core.exceptions import ComputeFollowsDataInferenceError
@dpex.kernel
def sum_kernel(a, b, c):
i = dpex.get_global_id(0)
c[i] = a[i] + b[i]
q1 = dpctl.SyclQueue()
q2 = dpctl.SyclQueue()
print(q1 == q2)
a = dpnp.ones(1, sycl_queue=q1)
b = dpnp.ones(1, sycl_queue=q2)
c = dpnp.empty_like(a)
sum_kernel[dpex.Range(1)](a, b, c)
Inside dispatcher when the type of the input arguments is inferred I see that all the args are inferred as usm_ndarray type with the same queue.
