Existing Tensor Libraries

What follows are the existing tensor libraries we are aware of. There are a ton of tensor libraries and we have limited ourselves to C++ libraries providing tensor functionality. The libraries are listed in alphabetical order.

Cyclops Tensor Framework (CTF)

Fastor

GitHub

Fastor ¹ is focused on tensors with known shapes.

Total tensor size must be known in advance (not just number of modes, but also the extents of those modes).

FTensor

GitLab

Intelligent Tensor (ITensor)

GitHub

libtensor

GitHub

PyTorch

Docs

I know what you’re saying, “Wait PyTorch is in Python” well they have a C++ API so it’s on the list.
