安装依赖失败
首次启动服务时，stable-diffusion-webui 需要下载大量依赖包，主要会出现以下情况：
卡住不动：大概率是网络不佳，因为有些依赖资源地址在国内是无法访问的，这时需全程启用代理，避免网络连接问题。
下载报错：有些依赖版本和自身系统不兼容，会导致报错，这时可根据具体报错信息去网上搜索解决方案。
启动成功，但部分依赖下载失败：可以通过手动安装来解决此类问题（例如在项目根路径下执行 pip3 install xxx，至于执行什么命令可根据报错信息中的提示进行尝试）。

ERROR: No matching distribution found for tensorflow解决方案：打开 stable-diffusion-webui/extensions/sd_smartprocess/requirements.txt 文件修改 tensorflow 为 tensorflow-macos，这是因为在 mac 上匹配不到 tensorflow 安装包，将其修改为 tensorflow-macos 即可。
