Bug
In the lvlb_weights calculation, the expression
1 - alphas_cumprod_prev / 1. - alphas_cumprodis parsed as1 - (alphas_cumprod_prev / 1.) - alphas_cumproddue to Python operator precedence, instead of the intended(1 - alphas_cumprod_prev) / (1 - alphas_cumprod).Fix
Added parentheses to ensure correct precedence matching the DDPM paper's posterior variance formula.
