"unknown builtin op" error with static library

[sausax]

Getting error while running libtorch example from https://pytorch.org/tutorials/advanced/cpp_export.html . Getting error only with static library. Shared library works fine.

./libtorch_test model.pt
terminate called after throwing an instance of 'torch::jit::script::ErrorReport'
  what():
unknown builtin op:

def mul(a : float, b : Tensor) -> Tensor:
  return b * a
         ~~~~~ <--- HERE
def add(a : float, b : Tensor) -> Tensor:
  return b + a
def ne(a : float, b : Tensor) -> Tensor:
  return b != a
def eq(a : float, b : Tensor) -> Tensor:
  return b == a
def lt(a : float, b : Tensor) -> Tensor:
  return b > a
def le(a : float, b : Tensor) -> Tensor:
Aborted (core dumped)

@yf225 any idea here? Seems like certain ops aren't getting registsred in the cpp build.

[ckhazan]

Any updates here please? Having exact same issue.

@yf225 what's the plan on this?
