sumer fattoum's questions

我有一个运行 linux 服务器（没有图形界面）的视频服务器，它有 2 个硬盘：

NAME                      MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
loop0                       7:0    0  55.4M  1 loop /snap/core18/1944

├─sda2                      8:2    0     1G  0 part /boot
└─sda3                      8:3    0   237G  0 part 
  └─ubuntu--vg-ubuntu--lv 253:0    0 118.5G  0 lvm  /
sdb                         8:16   0   7.3T  0 disk 
└─sdb1                      8:17   0   7.3T  0 part 

标准保存目录是/usr/lib/unifi-video/data/videos 我想将此目录更改为另一个硬盘驱动器（sdb），所以我使用了：

mkdir /mnt/videodrive

mount /dev/sdb1 /mnt/videodrive

结果：

loop1                       7:1    0  69.8M  1 loop /snap/lxd/19032

└─sda3                      8:3    0   237G  0 part 
  └─ubuntu--vg-ubuntu--lv 253:0    0 118.5G  0 lvm  /
sdb                         8:16   0   7.3T  0 disk

我可以只使用 /mnt/videodrive 将文件存储在另一个硬盘驱动器 (sdb) 上吗？

我使用 python 3.7，但也安装了 3.6 和 2.7，我使用的是 Ubuntu 16.04 LTS。

我将 python 的顺序更改为 python 2.7 仍然无法正常工作，我在 VMware 上使用它。我想我对 python3 进行了更改，我安装了很多包。

我正在尝试运行 jupyter notebook，但我无法弄清楚可能导致问题的原因。

当我尝试从终端运行 ipython 时，它显示：
