Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/21438 ghimport-source-id: 33f145f5b3508163365442c22a223c4a44e677d8 Differential Revision: D15738856 fbshipit-source-id: 656e8d0e3d0d22f116e3ab66bf0282608d6f1a76	2019-06-10 09:14:13 -07:00
Dmytro Dzhulgakov	c25e33789e	Lightweight at-most-once logging for API usage (#20745) ... Summary: Resubmit #20698 which got messed up. Idea is that when PyTorch is used in a custom build environment (e.g. Facebook), it's useful to track usage of various APIs centrally. This PR introduces a simple very lightweight mechanism to do so - only first invocation of a trigger point would be logged. This is significantly more lightweight than #18235 and thus we can allow to put logging in e.g. TensorImpl. Also adds an initial list of trigger points. Trigger points are added in such a way that no static initialization triggers them, i.e. just linking with libtorch.so will not cause any logging. Further suggestions of what to log are welcomed.
