Spyder stopped working after Anaconda matplotlib upgrade

Answer to question: What is described under "edit" made Spyder and Matplotlib work.

Spyder won't launch anymore. I use windows and Anaconda. Here's what's happened:

1) When Spyder worked, matplotlib did not work. When trying to plot something I got the error

AttributeError: 'module' object has no attribute 'to_rgba'

2) Based on this thread, I upgraded matplotlib by

conda upgrade matplotlib

Spyder would still not work. Among the error messages I got when trying to launch Spyder from the windows terminal was

"AttributeError: 'module' object has no attribute 'PLUGIN_CLASS'

and

raise PythonQtErrpr('No Qt bindings could be found')
qtpy.PythonQtError: No Qt bindings could be found

3) I then did 

conda update qt pyqt

which gave the last error of 2) when trying to launce Spyder.

4) I den did

conda install --force-reinstall pyqt qt

which also gave the last error of 2) when trying to launce Spyder.

Does anybody know how to fix this?

edit: I am not sure why, but I just discovered by running

python --version

that it is Python 2.7.15 and not Python 3 that is installed. However, I am pretty sure I was using Python3, since the print commands I was using was of the Python3 type. I will now try

conda update conda
conda install python=3.7.2
