Hello everyone!
I am having some trouble with PyPlot, can somebody help me?
I have Anaconda's Python 2.7 installed and normally Julia recognized it
while using PyPlot and PyCall but it suddenly failed today while importing
PyPlot:
ERROR: InitError: Failed to pyimport("matplotlib"): PyPlot will not work
until you have a functioning matplotlib module.
For automated Matplotlib installation, try configuring PyCall to use the
Conda Python distribution within Julia. Relaunch Julia and run:
ENV["PYTHON"]=""
Pkg.build("PyCall")
using PyPlot
pyimport exception was: PyError (:PyImport_ImportModule) <type
'exceptions.ImportError'>
ImportError('/home/ilya/anaconda2/lib/python2.7/site-packages/numpy/linalg/lapack_lite.so:

So I tried to reinstall julia and set ENV["PYTHON"] = "" before adding
PyCall to force the usage of Conda.jl ,
then I added PyPlot and everything seemed fine until then, but when I use
import PyPlot I get the following error:
ERROR: InitError: PyError (:PyImport_ImportModule) <type
'exceptions.ImportError'>
ImportError('cannot import name scimath',)

I get the same error if I try to use the development branch of PyCall
instead:
Pkg.checkout("PyCall")
ENV["PYTHON"] = ""
Pkg.build("PyCall")
And I get the same error when I try to use Anaconda as before by setting
ENV["PYTHON"] = "python" and building PyCall again. (with both versions of
PyCall)
The problem always appears when I try *using PyPlot*.
I don't know if this helps but if I try to continue and plot something I
get the following:
ERROR: ArgumentError: haskey of NULL PyObject
in haskey at /home/ilya/.julia/v0.4/PyCall/src/PyCall.jl:260
in plot at /home/ilya/.julia/v0.4/PyPlot/src/PyPlot.jl:457
Any help would be highly apreciated!
Thanks,
Ilya
