I have a problem with recent Spider's update:
You have missing dependencies, qt console >= 4.6.0: 4.5.2 (NOK).
This error appears every time I running program and during using i have problems with inputs.
I tried reinstall spyder, update spyder, update this qtconsole, update all and nothing.
See also the complete error window.
(Spyder maintainer here) To avoid this error you need to update qtconsole to its latest version, either with conda (if you use Anaconda) or pip otherwise.
