大家在使用comfyui过程中遇到的各种困惑和问题，可以通过提供、说明详细的线索信息，进而帮助分析、识别和解决。

为了装双截棍结果更新了python到3.11和pytorch2.8.0，结果不但双截棍用不了，好多之前的插件也用不了，比如xlab，提示入下，大哥能给看看不？

已经安装成功nunchaku，且成功出图，运行了别的工作流后，再次运行nunchaku文生图工作流，节点爆红失效，然后卸载多次，也无法再次安装节点，怎么回事阿，麻烦楼主看看

兄弟按照你说的降级pytorch2.6了，结果

安装完nunchaku插件以及对应版本的轮子依赖后就报有个过时version版本被安装与impact pack不兼容，这种有大的影响吗？应该如何解决？

一运行就报这个

An error happened while trying to locate the file on the Hub and we cannot find the requested files in the local cache. Please check your connection and try again or make sure your lnternet connection is on. 使用controlnet模型时出错了，请问一下如何解决

1、提示词长度问题。
Token indices sequence length is longer than the specified maximum sequence length for this model (328>77).Running this sequence through the model will result in indexing errors.
这个实测下来超77部分的提示词还是会反映到生成图片中，那这条警告可以不用管吗，还是最好把文本编码器换成A1111那种模式？但flux是不是没法用A1111模式呀？
2、cn模型的下载和读取问题。

翻译成中文也没懂什么意思，只知道它提示我缺模型，所以要在线下载。因为我之前用的是webui，从webui转comfyui，模型读取路径用的是webui，但我发现cn模型似乎无法从webui文件夹里读取，所以每次用cn都提示我要下载cn模型。但我没开v，所以每次下载都失败，失败之后它又能自己生成骨骼图，我都不知道它从哪里获取的模型。现在每次用cn，等它下载失败要等很久，后续生成倒是没问题，不知道要怎么解决这个问题

大佬求问这个是什么情况
