I want to use the pyplot backend to make some 3D scatter plots
using Plots; pyplot()
and I get the following:
sys:1: UserWarning: This call to matplotlib.use() has no effect because the backend has already been chosen; matplotlib.use() must be called *before* pylab, matplotlib.pyplot, or matplotlib.backends is imported for the first time. The backend was *originally* set to u'Qt5Agg' by the following code: File "/home/pegger/.julia/v0.6/Conda/deps/usr/lib/python2.7/site-packages/matplotlib/backends/__init__.py", line 14, in <module> line for line in traceback.format_stack() WARNING: No working GUI backend found for matplotlib WARNING: Couldn't initialize pyplot. (might need to install it?) INFO: To do a standard install of pyplot, copy and run this: if !Plots.is_installed("PyPlot") Pkg.add("PyPlot") end withenv("PYTHON" => "") do Pkg.build("PyPlot") end
I followed the instructions and restarted julia and tried again to use the pyplot backend, and I got the same thing.
Has anyone ever experienced this and how did you solve it?
