Sean Silva 485c18bb2f [torchdynamo] Add "lockstep" numerical accuracy debugger. ... Thanks to TorchDynamo's great layering and design, this is only about 100 lines of code for a basic lockstep debugger. This should allow us to deprecate eager_mode, since AFAIK the only interesting use case that it was really supporting is for downstream users to write lockstep debuggers. NOTE: The exact reporting and interface here is subject to change. Please try it out and provide feedback (or patches :) ). - make_fx should not drop source locations: https://github.com/pytorch/pytorch/issues/90276 - Report tensors better (huge tensors should be summarized) - Maybe don't abort, but just warn? - Allow customizing atol/rtol. - How best to print the failing node? And include surrounding graph context?		2022-12-06 07:57:45 -08:00
