渲染一段4秒480p的图生视频用了58分钟，显卡也是全力在跑的，为什么那么慢呢？我是刚刚接触Ubuntu系统的小白，请教各位大神我是不是哪里设置错了。</p>

<p dir="auto">你的CLIP调用了CPU，但也不至于这么慢，而且看你使用的模型似乎是FP8模型，不知道你为什么这么选，选一个更小的模型看看，GGUF格式的。这就是显存不够，频繁offload，跑大模型可以vulkan，跑comfyui只能rocm。你也打印下你的triton，torch版本，如果缺少triton，也会慢点和狗屎一样。还有AMD跑wan就是慢。24G跑Wan也慢，显存不够。</p>

<p dir="auto">我第一次CLIP没有调CPU的.58分钟.然后第二次调CPU也是58分钟.没有triton.模型是fp8</p>
