Error compiling PyCall

Hi guys,

I am trying to get started with Matplotlib. My environment is

versioninfo
versioninfo (generic function with 2 methods)

julia> versioninfo()
Julia Version 1.1.0

I am pointing to Julia’s Conda: ENV["PYTHON"]="". The command Pkg.build("PyCall") yields

…which does not make me wise. The only comment I can offer that

 ERROR: LoadError: IOError: could not spawn setenv(`'C:\Users\PHILIP~1\Ap1\packages\PyCall\ttONZ\deps\find_libpython.py'

is strange because the only user on this computer is philippem. Which raises the question of how the string PHILIP~1 appeared.

Launch in 3:45 minutes!!! :grinning:

You could be seeing something similar to https://github.com/JuliaPy/PyCall.jl/issues/688 … somehow, the JuliaPro setup on Windows sometimes want to install Conda into a weird temp directory. You can fix it by doing:

rm(abspath(first(DEPOT_PATH), "conda", "deps.jl"))

and then re-building Conda and PyCall.

(It would be nice if a knowledgable Windows user could reproduce and diagnose this problem.)

GREAT!
First I agree my issue is probably the same as https://github.com/JuliaPy/PyCall.jl/issues/688 (I did search before posting… not good enough).
Second, now PyCall compiles, which is bliss - I have been struggling with this for a looooong time!

Unfortunately, I then proceed to the next problem. ENV[“PYTHON”] does not exist, so I am using the default Conda (if I understand). I can Pkg.add, Pkg.update and “using” PyPlot (which is why I needed PyCall). But trying to execute

x = range(0; stop=2*pi, length=1000); y = sin.(3 * x + 4 * cos.(2 * x));
plot(x, y, color="red", linewidth=2.0, linestyle="--")

gives an error

julia> plot(x,y)

So… is my installation still faulty (probably…), or am I using PyPlot wrong?

OK, I have been snooping around a bit:


Inspired by this I get

julia> PyPlot.PyCall.python
"C:\\Users\\philippem\\AppData\\Local\\Continuum\\Anaconda3\\python.exe"

while

julia> ENV["PYTHON"]
ERROR: KeyError: key "PYTHON" not found

I wish to work with the Conda packaged with JuliaPro. I seem to have messed that up because I tried to connect to Anaconda in an earlier iteration.

How do I get PyPlot to use said Conda? Just set

PyPlot.PyCall.python = /.../.../Conda/.../Python.exe

Or is the procedure different?
