Error with QT Library When Calling `PyPlot` Uisng `PyCall` on Windows
I'm running the demo code on the README file:
plt = pyimport("matplotlib.pyplot")
x = range(0;stop=2*pi,length=1000); y = sin.(3*x + 4*cos.(2*x));
plt.plot(x, y, color="red", linewidth=2.0, linestyle="--")
plt.show()
I get the following error:
Then the REPL just crashes.
Could it be a missing installation by Conda or something?
Using Julia 1.6 on Windows 10.
If I set:
mat = pyimport("matplotlib")
mat.use("TkAgg")
Then it works.
FYI, fix here: https://www.dropboxforum.com/t5/Dropbox-installs-integrations/How-do-I-fix-the-Qt-platform-plugin-quot-windows-quot-error/td-p/91545
It's Windows/[ana]Conda related it seems, works for me on LInux.
But it used to work out of the box previously. I didn't need to manually install anything QT related.
By the way, PyQT is there (Basically QT5) in the Conda folder.
It should use it but somehow it doesn't.
Could it be because I installed MatPlotLib using Conda and not PyPlot?
Could it be that PyPlot would have download more dependencies and everything would work?
OK, I think I found some of the problems. It happened as I moved the installation folder of Julia.
In Conda folder there is a file called qt.conf which probably define the paths to the QT binaries.
Since it uses absolute paths, when I moved the folders it failed.
I wonder if there is a way to make PyPlot and PyCall regenerate their configuration files which include paths.
