@yongjun-liu 可以，开始实践吧！如果6.2的包有问题，你可以换6.3，更好一点，这是我测试过的稳定版，跑comfyUI非常稳。驱动我是Rocm7.2。
-
@terry 是不是我这个模型用的不对？我就用的官方带的自带的那个，现在运行起来巨慢，一张图还没出过呢。
@yongjun-liu 和模型无关，你贴下日志，肯定是降级到CPU了。

@terry 他说是加载了 Nvidia 的程序。
-
@terry 跑 7% 就卡死了。
-
@terry 学习到了。驾驭 G mini大法了。
这是核心教程啊。 -
@terry 他回答，CPU 正常，没问题。说是步数问题，操，指挥了半天，给我脑子指挥晕了。我休息两天吧。

我重装了Windows 11。comfyui
结果是这个,晕死我了.这是我新装系统的启动日志啊

@terry 刚才跑通了一段就用的是这个配置三秒钟720的视频用了13分钟.跑的鼠标都动不了。说的那个Q4的那个模型在哪啊您给个链接我去看看。多谢了啊哥们儿。
-
@yongjun-liu 大哥都说了你模型太大，用CPU计算了，没用显卡，卡的和锤子一样。你问AI去哪里下，不行去B站下载刘悦的整合包，它包里就带模型。b站，刘悦的技术博客。还不会就直接把电脑格式化，你不适合玩AI。
@terry 顶。我也不喜欢解释。浪费时间。
