大家好我是一个尝试使用稳定扩散的新手：'(我第一次尝试启动它，但每次都被这个错误卡住了，老实说，我真的不知道我现在应该做什么。

Answer 1

似乎必须在0.15 版本中重新安装httpcore

pip-install--强制重新安装httpcore==0.15
在找到其他修复程序之前是一种临时解决方法。或者只是将其附加到您的requirement.txt这来自httpcore的最新更新，与此存储库无关。

Answer 2

我通过在pipfile 中添加以下行解决了这个问题

httpcore = "<=0.15"

这是世卫组织使用pipenv 的解决方案

Answer 3

别觉得不好，对我来说，它是从窗口开始的。但自8月份以来，我已经尝试了几个发行版和安装程序，但它从未运行过一次。

更新：我一直在努力，终于成功了！我刚做的我用"；python启动.py"；每次出现错误时，我都会搜索并应用推荐的修复程序。。。祝你好运
