Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/67254 Fixes https://github.com/pytorch/pytorch/issues/65997 BC breaking: `output = torch.ops._test.leaky_relu(self=torch.tensor(-1.0))` now fails with the error `TypeError: __call__() got multiple values for argument 'self'` since we call into `OpOverloadBundle`'s `__call__` method that has `self` bound to it as its first argument. Follow up work: 1. disallow `default` as an overload name for aten operators. 2. Add a method to obtain a list of all overloads (exclude the ones registered by JIT) 3. Add methods/properties to `OpOverload` to access more schema information (types of input and output args etc) cc ezyang gchanan Test Plan: Imported from OSS Reviewed By: pbelevich Differential Revision: D33469839 Pulled By: anjali411 fbshipit-source-id: c3fc43460f1c7c9651c64b4d46337be21c400621
