上述两种并行策略,即序列并行和Classifier-Free Guidance(CFG)并行,已经被整合到xDiT项目中。在配备了L40(PCIe)GPU的系统上,我们对比了使用diffusers库的单卡CogVideoX推理与我们设计的并行版本在通过50次迭代生成49帧(6秒)720x480分辨率视频时的性能差异。

To condition the model on some additional inputc, we consider classifier-free guidance44, not requiring an additional classifierpθ(c∣xt). We steer the reverse diffusion process by replacingϵθby a linear combination of the conditional and unconditional noise estimates, that is ...
min_guidance_scale,max_guidance_scale: 使用 Classifiser-free Guidance (CFG) 的强度范围。SVD 用了一种特殊的设置 CFG 强度的机制,稍后我们会在采样代码里见到。 fps:输出视频期望的帧率。SVD 的额外约束。实际上这个帧率肯定是不准的,只不过提高这个值可以让视频更平滑。

2)guidance_scale代表文本提示对图像生成过程的影响程度。具体来说,它控制着有条件生成所使用噪声的比例。通常该值在7到8.5之间取值较好,如果取值过大,生成的图片质量可能会很高,但多样性会下降。 其中代表CFG,当越大时,condition起的作用越大,即生成的图像更和输入文本一致,当被设置为时,图像生成是无条件的,文本...
