Sorry, that was on me: https://github.com/JuliaPy/PyCall.jl/issues/320 Still, since this thread wasn't resolved, it may be a good thing if this gets exposed to more eyes, since other people may have (or have had) the same problem, and could comment confirming its resolution, or that it still occurs.

Re: [julia-users] Re: Running octave scrips from julia
Hi! Of course! The point is to call m-octave functions, more or less similar to matlab functions. I understand that matlab.jl package could be a good solution if it opened the octave engine instead of opening the matlab. But in this case, matlab.jl uses calls to C-libraries of Matlab (MxArray, mxClassID, mxComplexity, MSession, etc) which are not equivalent in Octave. Now, I am trying to find why oct2py doesn't work from Julia as other modules what do. I'll send an message if I can solve it.

[julia-users] Re: Running octave scrips from julia
I really think that for something like this to work reliably, we probably want a way to call octave directly from Julia, but that requires some effort. Sorry - I don't have anything useful to add for the PyCall route. I guess that even though convoluted, it would be nice if it worked. -viral On Saturday, February 7, 2015 at 12:33:23 AM UTC+5:30, astromono wrote: Hi all, I am getting to julia in recent months.

Re: [julia-users] Re: Running octave scrips from julia
I can run many pyton modules from julia, such as mayavi for example, that it is complicated but oct2py break at first. Rober El 06/02/15 a las 21:40, Steven G.
