About albedo scale in relight eval part

[ZyyZyy06]

Hi,

Thanks for your great works and code sharing.

I wonder how the base_color_scale in the eval_relighting_syn4.py is obtained? I noticed that a value is output when idx=0, is it set after getting a base_color_scale when the default base_color_scale=1.0?

Looking forward to hearing from you.
