thr, your solution of writing a Julia wrapper worked for me. thank you. i
wouldn't have thought of that. how did you think to do that, by the way?

I think I found a way to use pycall in parallel:
To get around the "cannot serialize pointer problem", I declared the corpus
delicti everywhere and wrapped it inside a julia function that is also
declared everywhere:
It's also kind of clumsy and I'm not sure if it applies to your problem,
but t
OK, I found a horrible work around that might be good enough (for me):
Here is a mock python script:
import math, time
x = math.sin(math.pi/4)
time.sleep(5) # mock local work
print(x) # spit it out to julia
and here is the julia code that runs it:
r = @spawn readall(`python example.py`)
sleep(
So I got something working for my pylab example.

julia> PyCall.@pyimport pylab
julia> @everywhere import PyCall
julia> @everywhere PyCall.@pyimport pylab
julia> @everywhere A = pylab.cumsum(collect(1:10))*1.

@Matthew: did you find a solution?

Yea, right? So what’s the answer? How can we if at all do any PyCalls
parallely?
