Google Colab与tkinter一起挂起（python模块）

Question

我已经尝试通过google colab笔记本测试Deaf Communicator GitHub project，如您在此处看到的： https://colab.research.google.com/drive/1LdZEEuwKkIHfydVI3lhMfk1QjWbHDUb7?usp=sharing

此GitHub项目需要tkinter python混乱，并且基于 this post，我尝试使用以下代码修复tkinter模块的colab问题，但问题在于它挂在运行以下命令上：

!apt-get install -y xvfb # Install X Virtual Frame Buffer
import os
os.system('Xvfb :1 -screen 0 1600x1200x16  &')    # create virtual display with size 1600x1200 and 16 bit color. Color can be changed to 24 or 8
os.environ['DISPLAY']=':1.0'    # tell X clients to use our virtual DISPLAY :1.0
%cd /content/deaf-communicator
!python -m DEAF.py

结果如下：

因此，如果可能，请查看它以修复该错误。 还问这里： https://github.com/shubham-thakare/deaf-communicator/issues/1
