First step at adding exceptions (#12789) Summary: This is a first step towards adding exceptions. We need minimal support in order to begin converting the torch library to weak script mode (which is the main goal here). Some limitations (that are documented in the tests & compiler): 1. Cannot assign exceptions to variables 2. Any name after raise is being treated as a valid Exception 3. No control flow analysis yet. Below a will be undefined: if True: a = 1 else: raise Exception("Hi") return a Pull Request resolved: https://github.com/pytorch/pytorch/pull/12789 Differential Revision: D12848936 Pulled By: eellison fbshipit-source-id: 1f60ceef2381040486123ec797e97d65b074862d 2018-10-31 03:20:26 +00:00			`(def`

Support custom exception message (#41907) Summary: Raise and assert used to have a hard-coded error message "Exception". User provided error message was ignored. This PR adds support to represent user's error message in TorchScript. This breaks backward compatibility because now we actually need to script the user's error message, which can potentially contain unscriptable expressions. Such programs can break when scripting, but saved models can still continue to work. Increased an op count in test_mobile_optimizer.py because now we need aten::format to form the actual exception message.
