ReshapedArray causes scalar indexing

[ChrisRackauckas]

using CuArrays
CuArrays.allowscalar(false)
dp = cu(ones(252)')
p  = cu(ones(252))
reshape(dp,size(p)) # Error
vec(dp) # Error

Dup of https://github.com/JuliaGPU/CuArrays.jl/issues/508. You're working with a ReshapedArray{Float32,1,LinearAlgebra.Adjoint{Float32,CuArray{Float32,1,Nothing}}.

Is there a way to concretize this? A copy or something as a workaround?

[maleadt]

You can pass the Adjoint to the CuArray constructor to materialize it. Or add the necessary method to have it actually dispatch to what you want (or select the GPU BroadcastStyle).

The issue here is that I don't know if it's a CuArray. Is this something that needs Adapt.jl?

Dope, the easiest workaround for me was just dp' haha, take care.
