Update the descriptive error message for enforce fail (#31575)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/31575
We need a new exception class specifically for the enforce_finite operator, because we need to map it to a specific python exception ExitException, not the RuntimeError type that all c10::Errors get mapped to by default. This diff includes:
- Define c10::EnforceFiniteNotMet
- API CAFFE_ENFORCE_FINITE to throw c10::EnforceFiniteNotMet
- Map from c10::EnforceFiniteNotMet to python ExitException
- Apply CAFFE_ENFORCE_FINITE in caffe2 op
Test Plan:
- integration test pass: https://fburl.com/fblearner/xwkzbqyo
- integration test with D19213617: https://fburl.com/fblearner/479y4jrj Generate error message as desired
- Example:
- Original error message f157597803
{F225477055}
- Updated error message (with D19213617 to generate the error): f158571327
{F225477071}
