一、报错信息

UserWarning: __floordiv__ is deprecated, and its behavior will change in a future version of 
pytorch. It currently rounds toward 0 (like the 'trunc' function NOT 'floor'). 
This results in incorrect rounding for negative values. To keep the current behavior, use 
torch.div(a, b, rounding_mode='trunc'), or for actual floor division, 
use torch.div(a, b, rounding_mode='floor'). 
scales = 0.5 + (areas - min_area) // (max_area - min_area)

二、错误分析

大概意思就是向下取整运算符 // 已经被废弃，使用torch.div(a,b,rounding_mode=‘floor’)或者torch.div(a,b,rounding_mode=‘trunc’)

torch.div(a,b,rounding_mode
