今天在一台新的机器环境装了SDWEBUI，都使用最新的版本，升级了下换脸的插件，于是乎启动崩溃了。错误如下

google了下是pydantic要使用1.10.15版本

于是乎降级pydantic，发现gradio和albumentations又报错了，因为依赖最新的版本，结果还得给gradio和albumentations降级。降级到去年年底的版本

折腾了一个小时。。。。。降级后错误依旧，没道理

冷静。。。。。

索性uninstall掉gradio，发现错误依旧。。。。

有点头绪了，怎么没uninstall掉，仔细看了下目录，里面还有个坑爹的venv，再进去看，gradio还是原来的版本。有头绪了，估计我使用的conda环境对venv没作用

source /mnt/e/sd-webui-aki-v4.7/venv/bin/activate
一下，进去venv了

把降级的操作重做一遍：

pip uninstall pydantic
pip uninstall gradio 
pip uninstall albumentations

pip install pydantic==1.10.15
pip install gradio==3.50.2
pip install albumentations==1.3.1

然后启动sd。。。

熟悉的界面终于出来了，内牛满面
