Thanks for your attention! I will explore this possibility in the next few days and let you know. I will release it with either --fp16
option or a new branch.

Hi,
The half-precision support with apex
library is now available for pre-viewing. You could switch to it by
git checkout fp16
, and adding argument --fp16
to any bash commands would run with apex, e.g.,
bash run/vqa_finetune.bash 0 vqa_lxr955_tiny --tiny --fp16
I would really appreciate it if you could help test it!
Comments:
-
Fine-tuning results with fp16 has been verified: VQA: 70.12, GQA: 59.81, NLVR2: 74.26. Pre-training with fp16 has not been verified.
-
Performance: VQA/GQA/Pre-training's speed is not changed, but the memory is reduced. NLVR2 gets 2x speed gain.
