  • Migrate as much code of the ffi bindigns from hand-written code to autocxx
  • Add support for the TRT-RTX builder interface to allow creation of networks without ONNX.
  • Change the NetworkDefinition interface to return layers instead of Tensors to be closer to the original API
  • Replace custom cuda FFI wrapper by cudarc
