What Hacker News says?
i wonder how this compares with einsum https://ajcr.net/Basic-guide-to-einsum/ > The einsum function is one of NumPy’s jewels. It can often outperform familiar array functions in terms of speed and memory efficiency, thanks to its expressive power and smart loops it seems like einsum has been ported to torch & tensorflow https://numpy.org/doc/stable/reference/generated/numpy.einsu... ; https://pytorch.org/docs/stabl…
