Missing new memory intrinsic on v1.11: No augmented forward pass found for jl_genericmemory_copyto #2077
Open
Description
Fairly tame MWE:
using Enzyme
u = [rand(2),rand(2)]
_u = Enzyme.zero(u)
B = rand(2,2)
_B = rand(2,2)
I = ([1,2],Colon())
function f(B, A)
B .= stack(getindex.(u[last(I)], tuple.(Base.front(I))...))
nothing
end
f(B,u)
Enzyme.autodiff(Reverse, f, Duplicated(B, _B), Duplicated(u, _u))ERROR:
