conda Solving environment: unsuccessful initial attempt using frozen solve. Retrying with flexible solve

引用\[1\]和\[2\]中提到的错误信息表明，在安装`annoy`包时出现了找不到对应包的错误。这可能是因为当前的软件源中没有该包。解决这个问题的方法是尝试使用其他软件源来安装该包。

引用\[3\]中提到的解决方法是将清华镜像源添加到PIP的搜索目录中。你可以在Anaconda Prompt中输入以下命令来设置清华镜像源：

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

这样设置后，再次尝试使用conda安装`annoy`包，应该就能成功解决问题了。

总结回答：你遇到的问题是在使用conda安装`annoy`包时出现了解决环境的错误。解决这个问题的方法是将清华镜像源添加到PIP的搜索目录中，然后再次尝试安装该包。
