Currently a experimental and unofficial packaging for pytorch is available here:
https://github.com/cdluminate/pytorch

Pre-built binary packages:
https://github.com/CDLuminate/pytorch-debs

Different from the Torch7 packaging, Debian/Ubuntu users should be able to create their own Pytorch .deb package with my scripts.

This is still a work in progress, and may turn into Official Packaging when it's ready.
