root@nu1mmmnfz5:/notebooks/LoRA# which python3.10
/usr/bin/python3.10

系统存在/usr/local/bin和/usr/bin两个路径，通过apt -y install python3.10安装的Python3.10位于/usr/bin路径下，曾因该安装操作无法顺利完成陷入困境。

已尝试操作 #

• 执行系统更新与安装命令：

apt update -y
apt upgrade -y
apt -y install python3.10

• 尝试使用update-alternatives配置默认Python版本，操作及结果如下：
  1. 执行命令：update-alternatives --install /usr/bin/python python /usr/bin/python3.10 1
  2. 执行命令：update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 1
  3. 执行update-alternatives --config python时，报错：update-alternatives: error: no alternatives for python
  4. 执行update-alternatives --config python3时，报错：update-alternatives: error: no alternatives for python3
