Discussion:
When performing license check on Pytorch debian package I found this license problem: License of Pytorch is BSD-3-Clause, however THHalf.c is non-free according to its header.
A possible replacement can be found in in NNPACK (BSD-3 licensed).
Actually NVIDIA's copyright declaration in THHalf.c makes it impossible for Pytorch to enter the main section of Debian archive. To promote to official package, we should have copyright problems cleared at first.
We're working on getting this cleared -- sorry for the inconvenience.
Marking as done since was merged.
It's my bad. The fix entered torch/torch7 but is still not synced into pytorch.
Did you want me to patch pytorch separately? I figured the file can now be copied over from torch by anyone.
i'll sync the subtrees now!
Thank you guys.
