我无法在 python2.7 上安装 python-tk

我是 Ubuntu Mate 16.04 用户。我想运行这个程序。我必须使用 python2.7 来运行该程序。然后我输入

python2 train_and_test.py

在终端上。然后，显示一个错误。

ImportError：没有名为 _tkinter 的模块，请安装 python-tk 包

因此我尝试安装 python-tk。我输入

sudo apt-get install python3-tk

安装成功。接下来，我输入

sudo apt-get -y install python-tk

但安装失败。

我已经更新了apt-get。我应该如何安装python-tk？
