The tests pass, but they shouldn't -- torch.amp was only added in 1.10. |

This pull request adds decorators to
EntmaxBisectFunction,SparsemaxBisectFunction,Entmax15Function, andSparsemaxFunctionso that they will autocast to 32-precision if they occur inside an autocast context. This seems to be the right thing to do because bf16 and fp16 introduce numerical stability issues that cannot easily be solved. Upcasting should make it easy to incorporate entmax into any mixed-precision setting.The actual code that needed to be written was incredibly simple; the vast majority of commits are me making silly mistakes while writing the tests.
