Ubuntu20.04 conda安装出错
成功解决conda安装 Pytorch 时提示：solving environment：failed with initial frozen solve.Retrying with flexible solve
遇到的问题
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
这是我在安装 Pytorch 过程中遇到的，总是环境不对，所以就查阅了一下，后面经过尝试，问题解决了，来记录一下，备忘。
一、先说说我成功解决的方法：
更新conda:
切换到 root 用户，然后输入 conda updata，根据调出来的提示信息，更新conda,如下：
su root # 这里会提示输入密码，输入 root 用户的密码即可
conda update
输入之后等待他完成之后就可以继续安装 pytorch 了
###############分割线########################
这里也补充说明一点我为什么要切换到 root 用户
===》单纯的是因为我用 sudoer 账号不能执行，说他没有权限，
你们也可以尝试不用切换到 root 账号看是否能行
如果后面的 verify 显示的是 done ，那就没问题，如果显示是filed 那可以尝试我前面说的这个方法
二、我也说说我用了没起作用的方法，如果上面的方法不适用，可以参照：
1、更新conda:
这里和上面不同之处在于我输入的命令不同：
这个命令会执行的很快，但是更新之后对解决问题不起作用
conda update -n base conda
2、设置镜像优先权:
conda config --set channel_priority flexible
**三、还有一些我查了，但是还没来得及用，如果上述方法都没能解决，可以尝试（黑色代码框里显示的是链接地址）：
1、重装并更新conda:
这个使用 widows 或者有图形界面的 Linux 系统

2、python 与 conda 版本冲突，将python版本换低一点:
