Load pickle files in Matlab

It’s easy enough to load .mat files in Python via the scipy.io.loadmat function. But what about loading .pickle files into Matlab? That’s easy enough by calling a system command in Matlab, like so:

function [a] = loadpickle(filename)
    if ~exist(filename,'file')
        error('%s is not a file',filename);
    end
    outname = [tempname() '.mat'];
    pyscript = ['import cPickle as pickle;import sys;import scipy.io;file=open("' filename '","r");dat=pickle.load(file);file.close();scipy.io.savemat("' outname '",dat)'];
    system(['LD_LIBRARY_PATH=/opt/intel/composer_xe_2013/mkl/lib/intel64:/opt/intel/composer_xe_2013/lib/intel64;python -c ''' pyscript '''']);
    a = load(outname);
end

Note that I’m setting the LD_LIBRARY_PATH environment variable since Matlab seems to reset this variable internally and it causes .so module import errors in Python.

  1. When I try this I seem to be getting this error – File “/path-to-python-packages/scipy/io/matlab/mio5.py”, line 857, in put_variables
    for name, var in mdict.items():
    AttributeError: ‘list’ object has no attribute ‘items’
    I am using scipy 0.13 – Any Idea what could be going wrong here ?
