What is Aten, is Aten a standalone library or created by Pytorch team?

Hi, I’m new to Pytorch and try to figure out structure of Pytorch repo.

I notice that

ATen is fundamentally a tensor library, on top of which almost all other Python and C++ interfaces in PyTorch are built. It provides a core Tensor class, on which many hundreds of operations are defined.

Is ATen created 100% by Pytorch core team or Pytorch use this standalone library in C++ and build from that? Thank you.

ATen was developed by the PyTorch team and I believe @zdevito came up with the name (“A Tensor Library”), but please correct me if I’m wrong. @ezyang can certainly add more details to the history of ATen.

as @ptrblck said, its created by pytorch team for pytorch core use
