I've suddenly been having a great deal of trouble with PyPlot on Julia
0.4.6 on Mac.
Here's one sort of problem I've gotten:
julia> plot([1,2],[1,3])
ERROR: ArgumentError: haskey of NULL PyObject
in haskey at /Users/ers/.julia/v0.4/PyCall/src/PyCall.jl:292
in plot at /Users/ers/.julia/v0.4/PyPlot/src/PyPlot.jl:381
I tried reinstalling PyPlot, PyCall, Conda and I get this:
