I think some of you know it, and I just saw it on the news today.
It looks like it is in Pytorch. The code is from an MIT professor, and he created this software concept when he was working in a startup, NeuralMagic, Inc. His name is Aleksandar Zlateski. After he went to Facebook, he open-sourced this in Pytorch, so we can use CPU to execute. But the startup does not want him to open source it. Right now Facebook is being lawsuit by the startup to remove the code.
