Motivation for this change

Added labelImg.

One issue is that when I run it, I get a message about:

/nix/store/xn5gv3lpfy91yvfy9b0i7klfcxh9xskz-bash-4.4-p19/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
/home/cmcdragonkai/.includes_sh/shell_environment_common.conf: line 31: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

But the rest works.
