I was thinking about the issue of how to easily distribute the software.
I think a good way would be to follow the standard convention where, after your clone the github directory, you go to the root directory and run "python setup.py install" which defines the different data directories and also sets environment variables that point to where the data is on gordon etc.
Then there should be scripts for uploading to gordon, setting the parameters for the gabor filters etc, downloading results and then opening these results in the GUI.
I tried to refactor the code, so that there are FeatureExtractor class and ModelDetector class. However calling joblib Parallel functions within class methods causes "can't pickle instancemethod".
possible solution: use new serialization method, such as dill, which is implemented within pathos
reference: http://stackoverflow.com/questions/19984152/what-can-multiprocessing-and-dill-do-together
joblib is not yet using dill, although it is on their todo list (https://github.com/joblib/joblib/search?q=dill&ref=cmdform&type=Issues). So I tried to use pathos.multiprocessing directly,
from pathos.multiprocessing import ProcessingPool as Pool
Installation of pathos: official website is http://trac.mystic.cacr.caltech.edu/project/pathos, but that release is very stale. Instead, use the development version https://github.com/uqfoundation/pathos and follow the instructions in the repo
This manages to do feature computation perfectly, but degrades to using only 2 or 3 processes at texton computation. I have no idea why.
