Spyder (Ubuntu 18.04) Segmentation Fault错误解决方案

1、Ubuntu环境下，安装了tensorflow，运行Spyder，出现Segmentation Fault错误

2、原因查找：

    1）pyqt、qt都已经安装；

    2）pip install - U spyder，重新安装，仍然报错；

3、环境描述

4、解决方案(上面一堆废话都不需要看了)

1. # pip3 install pyopengl

• 重点检查pyopengl有没有安装，如果没有安装，铁定就是他的原因了

   2. Add  from OpenGL import GL  to site-packages/spyder/app/start.py（可能已经存在）

• # This import is needed to fix errors with OpenGL when installed using pip
  # See issue 3332
  try:
      from OpenGL import GL
  except:
      pass
  

愉快的使用spyder吧……
