ComfyUI SDWebUI升级pytorch随记

目前使用的版本是去年10月的1.6版本，有点老。希望支持新的特性，于是乎开始作死。从升级torch开始。先看看已有的版本：

(venv) root@ubuntu-sd-server:~# pip show torch
Name: torch
Version: 2.0.1
Summary: Tensors and Dynamic neural networks in Python with strong GPU acceleration
Home-page: https://pytorch.org/

然后开始升级最新的2.1.1。幸好空间留的大，升级把一堆相关的都升上去了，好家伙，一下干了快3个G。

最后还ERROR了，友善的告诉我，xformers要挂了（之前为了节约内存和加速安装了xformers，看了下，最新的版本正好支持torch 2.2.1，于是顺便把xformers也升级了：

又干去222M。。

还有个pyre-extensions提示没装，顺手也装上。

然后拉了最新的ComfyUI，纯净没插件的能跑正常。

把SDWebUI 1.6也启动起来，不出意料的挂了：

网上查了一下报错，原来是torch新版本的functional_tensor改成_functional_tensor了，于是vi一下/root/sd-webui-aki-v4.4/venv/lib/python3.10/site-packages/basicsr/data/degradations.py，把文件里的调用修改一下，再启动。

很好，SDWebUI启动起来了
