Building Extension

Setup.py ==>

1. Cmake Link1 Link2
2. Define loading extension torch._C Link

Torch C extension (bindings)

Initialization of torch._C Link Notice the method list defined here and how methods are appended to the module Link

Implementation of torch.tensor

Important Link

1. Import TH/TH.h link
2. Import ATen/Aten.h link
