Problem with python3 on Debian Wheezy

[sam81]

I'm unable to load PySide when I initialize PyCall with python3 as follows:

julia> using PyCall

julia> pyinitialize("python3")

julia> using PySide
ERROR: PyError (PyEval_EvalCode) <class 'TypeError'>
TypeError('exec() arg 1 must be a string, bytes or code object',)

@sam81 Thanks for the report. Can you see if this call works with python 3:

PyCall.pyeval("execfile(x, globals())", x = Pkg.dir("PySide", "tpl", "imports.tpl")) 

For some reason (long forgotten) I added this code to get it to work under python 3

PyCall.pyeval("exec(open(x, 'rb'), globals())", x = Pkg.dir("PySide", "tpl", "imports.tpl"))

but it is now failing as exec wants only 1 argument.

PyCall.pyeval("exec(open(x, 'rb').read(), globals())", x = Pkg.dir("PySide", "tpl", "imports.tpl"))

You forgot the .read()...

Thanks. Just pushed that change to the master on github.

Thanks, I can confirm that the fix pushed on the master branch works.
