Hello,
I'd like to use your library to calculate the outer product of 3 sparse vectors. In numpy I can do np.outer(np.outer(u,u),u) or similarly use einsum with a dense matrix in Julia but your library is one of the few that supports high dimensional sparse tensors. How can I do this operation with SparseArrays?
I can define u = SparseArray{Float32}(undef,(5,1)) and get the sparse vector. I can do u * u' to get the first outer product but cannot get the third outer product to work.
And finally how can I contract this result with another rank 3 tensor that is not of the type SparseArray (I think this should be easy I'm just struggling to figure out the source code)?
