Almar,
i'm using...
Python 3.5.2 |Anaconda custom (32-bit)| (default, Jul 5 2016, 11:45:57) on
Windows (32 bits).
This is the Pyzo interpreter with integrated event loop for PYQT5.
Using IPython 5.1.0 -- An enhanced Interactive Python.
I tried to install PYQT4 rather than PYQT5 but not sure how to do that with
pip.
This could also be an IPython 5.1.0 bug...MPL code works fine from
command> py .py
I just need to add the plt.show() command and it works fine
Is there some way to run my code from another shell
Or How do I back out of Ipython?this bug seems to have something to do
with interactive mode
Bob
