Initially, I installed spyder 3 using sudo pip install spyder and everything worked well.
After that, I was trying to solve the issue of having very small icons in high resolutions screen discussed here.
For that, I installed pyqt4 (since I'm using python 2.7) using sudo apt-get install python-qt4, but the small icons problem wasn't solved because I realized I needed pyqt5.
I then installed it and some dependencies:
python3-pyqt5
python3-pyqt5.qtsvg
After this step, I couldn't open spyder anymore and got this error message:
Traceback (most recent call last):
File "/usr/local/bin/spyder", line 11, in <module>
sys.exit(main())
File "/usr/local/lib/python2.7/dist-packages/spyder/app/start.py", line 143, in main

File "/usr/local/lib/python2.7/dist-packages/qtpy/QtSvg.py", line 14, in <module>
from PyQt5.QtSvg import *
ImportError: No module named QtSvg
I tried uninstalling pyqt5, and also pyqt4 and reinstalling them (one without the other), but nothing seems to work.
I think I have the module QtSvg installed, but it seems spyder is not pointing at it correctly and I don't know how to fix this.
