Spyder anaconda crashes on Linux with segmentation fault

I just installed Anaconda on Linux. When trying to open spyder (either from navigator or terminal), it does not work. I get the following error when I try to open it in term

Answer 1

Based on my experiences, if you have ubuntu 18.04, anaconda 4.5 or higher, and spyder 3.3 or higher, installing pyopengl does not work, since spyder 3.3 should handle it. As recommended above, before start fixing it try to update spyder first:

conda update spyder

then downgrade Qt:

conda install pyqt=5.6

It should probably fix your problem. Other solutions could be found here:
