It's really great, thanks @myleott ! I think we could add some doc around that to make sure it's exposed and known, I can do that in the coming days if you'd like |

* [chore] Fix lint errors that broke master (#348) authored-by: Anjali Sridhar <anj@devfair0443.h2.fair> * [fix] ShardedDDP - cpu testfix - remove Gloo/CPU (#350) * no idea about the root issue, but it proved to be fairly narrowed (gloo+cpu+python3.8+no cuda installed) so I guess that's out of scope for fairscale * [feat][OSS] elastic and pytorch compatible checkpoints (#310) * adding a test to prove the inter operability with upstream pytorch * updating the changelog * eager state pruning * pytorch 1.5 compat * [fix] ShardedDDP - properly handle post device change (#353) * adding the .to(device) support + unit testing * doc update * [feat] Add AdaScaleWrapper (#347) * [feat] Add AdaScaleWrapper - This enables a different API for wrapping an optimizer with AdaScale. - This also enables AdaScale to be wrapped by OSS. - However, OSS wrapping AdaScale results in different optimization, which future research will be needed to study its effects. testing: add unit tests. * addressed comment: typo * [refactor] Refactor and enable multiprocess nn.Pipe benchmarks. (#319) * mp cleanup * round of multiprocess refactoring * test golden run * print cuda stats * fix lint errors * enable multiprocess pipe benchmarks * set world size to be available gpus * more changes * use synthetic loaders for intermediate pipeline stages * merged master * fix for the devices property * dataloader fix * modify rank check * print wps stats * enable verification * fix logging * fix flag name * fix flag name * check for rank * fix indent * pass args * pass args * modify golden data * remove unused print messsage * fix lint errors * add comments * fix benchmarks Co-authored-by: Anjali Sridhar <anj@devfair0443.h2.fair> * [refactor] pipe: simplify balance and module checks (#346) * [chore] v0.1.5 (#355) * [chore] disheartening switch off of a OSS cpu test (#356) * precise skip, only if agent has only cpu * [feat][minor] OSS Benchmark - regression test + background testing new optims (#352) * restoring the regression test, adding a test of the for_each optims * fix the regression test on circleci * removing unused flags * [refactor] multiprocess_pipe: cleanup __init__ (#357) * [refactor] multiprocess_pipe: remove retain_graph __init__ param (#358) It is not currently being used so we can simplify the interface by removing it. * [refactor] multiprocess_pipe: focus on LazyModule usage (#360) * [feat] ShardedDDP : Adding a proper DDP parity / AMP unit test, overdue (#361) * Adding a proper ddp parity / AMP unit test, overdue * catch non-AMP pytorch * [perf][OSS] Clip grad norm : minor obvious speedup (#363) cache this iterator, easy speed up * [refactor] multiprocess_pipe: remove pipelined_backward (#362) * [perf] ShardedDDP - small memory use reduction - minor speedup (#366) * minor * minor * [fix] repro+fix (#365) fix a broken earlier commit, only worked for the first step * [refactor] OSS only use flat buffers (#371) * flat params all along, way simpler * updating the docstring * [refactor] AsyncPipe: do not sub-class MultiProcessPipe (#370) * [refactor] remove multiprocess dependency on async (#373) * [fix] Workaround need for pip --no-build-isolation (#375) * Add fairscale.nn.misc.checkpoint_activations (#376) * Add fairscale.utils.containers Co-authored-by: Min Xu <24926999+min-xu-ai@users.noreply.github.com> * Add fairscale.nn.misc.checkpoint_activations Co-authored-by: Sam Shleifer <sshleifer@gmail.com> Co-authored-by: Min Xu <24926999+min-xu-ai@users.noreply.github.com> Co-authored-by: Sam Shleifer <sshleifer@gmail.com> * [chore] v0.1.6 (#377) * v0.1.6 Co-authored-by: anj-s <32556631+anj-s@users.noreply.github.com> Co-authored-by: Benjamin Lefaudeux <blefaudeux@users.noreply.github.com> Co-authored-by: Anjali Sridhar <anj@devfair0443.h2.fair> Co-authored-by: msbaines <35972327+msbaines@users.noreply.github.com> Co-authored-by: Leonard Lausen <leonard@lausen.nl> Co-authored-by: Myle Ott <myleott@fb.com> Co-authored-by: Sam Shleifer <sshleifer@gmail.com>
