Question about weight decay setting

[delaprada]

Hi, thank you for providing such good work.

I have question about the weight_decay setting in run_metro_handmesh.py. The weight_decay is strictly set to 0 for Adam optimizer. But according to the Freihand training reproduced log provided in EXP.md, the weight_decay is 0.05.

May I ask which setting is more appropriate?
Thank you!
