Error in using PyPlot in Julia

[fksayaci]

Hi,

I use Julia for optimization purposes. I use PyPlot for visualization of the results.

I have used Windows and Mac computer so far, and there was no problem at all.

I recently switched to a Windows computer, installed Julia and Atom. When I type “using PyPlot” it gives the following error.

As the error says, I typed Pkg.build(“PyCall”), but it gives another error. I can not post the picture of it, but it says that it could not find system-wide Python.

I could not resolve this problem.

There is a similar discussion here in this forum, but it did not help me to figure this out.

Error in using PyPlot in JuliaPro

Can anyone tell me why the PyPlot doesn’t work even though I have installed PyPlot and PyCall ? The version of my JuliaPro is 1.1.1.1. Here is the error message: julia> using PyPlot [ Info: Precompiling PyPlot [d330b81b-6aea-500a-939a-2ce795aea3ee] ERROR: LoadError: LoadError: PyCall not properly installed. Please run Pkg.build(“PyCall”) Stacktrace: [1] error(::String) at .\error.jl:33 [2] top-level scope at C:\Users\86139.juliapro\JuliaPro_v1.1.1.1\packages\PyCall\ttONZ\src\startup.jl:…

Your help will be much appreciated.

Kind regards

I solved this problem. I had two Python installations in my computer. One is individual installation that I did, and the other is Anaconda installation. Individual installation was 32-bit. What I did is to define ENV[“PYTHON”] to Anaconda installation, which is 64-bit. Then, I run Pkg.build(“PyCall”), and restated Julia. This solved the problem.

However, now when I run “using PyPlot”, it says that matplotlib does not match with Python installation. I do not have the Windows computer now. I will upload the error when I have that.

Kind regards
