Summary: Resolves https://github.com/pytorch/lockdown/issues/29 Examples: ``` import torch torch.jit.script def foobar(x): return torch.blargh(xyz) == RuntimeError: object has no attribute blargh: at compile.py:5:12 torch.jit.script def foo(x): return torch.blargh(x) ~~~~~~~~~~~~ <--- HERE ``` It also gets the correct column number in the case where the original source file has common leading whitespace in front of the callable: ``` import torch with torch.no_grad(): torch.jit.script def foo(x): return torch.blargh(x) == RuntimeError: object has no attribute blargh: at compile_leading.py:6:24 torch.jit.script def foo(x): return torch.blargh(x) ~~~~~~~~~~~~ <--- HERE ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/20898 Differential Revision: D15552424 Pulled By: jamesr66a fbshipit-source-id: 78d0f0de03f7ccbf3e7ea193a1b4eced57ea5d69
