How to combine portable Julia with Portable Python under Windows7 for e.g. PyPlot?

[Manfred]

As Julia user I  am below novice level which is due to the fact that I have not yet managed to complete the Installation of my Julia Environment successfully. My main Problem is to bring PyPlot to work from within a portable Julia "Installation" along with a portable "Python" Installation.

Basic stuff with Julia alone and Juno in combination with Julia work, but so far, I get the following command/error message Dialog when trying to plot with PyPlot:

julia> using PyPlot
Warning: error initializing module PyPlot:
ErrorException("could not load module python: The specified module could not be
found.
")

Conditions:

Computer/OS:

Window7 Enterprise

Service pack 1

Intel(R) Core(TM) i5-3320M CPU @2.6 GHz, 4 GB RAM

64 bit OS

no ADMIN rights, thus, the need for portable use!

In standalone mode and accessed via Spider, Basic Python functions work and I am able to do plotting with matplotlib. 

Clearly, the two portable installations do not know of each other so that I have experimented with setting the Julia Environment variables to all sorts of values, however, without success. Below only some examples:

ENV["PYTHONHOME"] ="C:\\Daten\\portable\\WinPython-64bit-2.7.9.1\\python-2.7.9.amd64"

ENV["PYTHONPATH"]="C:\\Daten\\portable\\WinPython-64bit-2.7.9.1\\python-2.7.9.amd64\\libs"

ENV["PYTHONPATH"]="C:\\Daten\\portable\\WinPython-64bit-2.7.9.1\\python-2.7.9.amd64\\Lib"

.....

alternatively and concurrently, I have tried to set the according Windows Environment variables (each time re-starting "command-line Julia" thereafter ):

set PYTHONHOME=C:\Daten\portable\WinPython-64bit-2.7.9.1\python-2.7.9.amd64\
set PYTHONPATH=C:\Daten\portable\WinPython-64bit-2.7.9.1\python-2.7.9.amd64\libs

.....

Any hints?

I cordially apologize, if the answer is apparent and I am just too illiterate!

I think I've had the same problem. I was given the advice of  installing the Anaconda distribution of python..
That worked.

This is what I do to use WinPython

First I created a batch in the WinPython root dir at the image of that inside the scripts dir (env.bat). In my case it has

(env2.bat)
@echo off
set WINPYDIR=%~dp0python-2.7.6.amd64
set WINPYVER=2.7.6.3
set PATH=%WINPYDIR%\Lib\site-packages\PyQt4;%WINPYDIR%\;%WINPYDIR%\DLLs;%WINPYDIR%\Scripts;%~dp0tools;%~dp0tools\gnuwin32\bin;%~dp0tools\mingw32\bin;%PATH%;
SET PYTHONHOME=%WINPYDIR%

Next, I call julia via a batch (julia.bat) that has

call C:\programs\WinPython2.7.6.3_64\env2.bat

and all works well and does not clutter the path

There is also  procedure here (currently for julia 0.3.3, but you can tweak for 0.3.5), that may help.
