Error when running the classifier

[thisisthechris]

Hi All,

I'm working on creating a reusable development environment for this project using Virtualbox, Vagrant and Ansible. I'm very close, but at the moment at get the following error whenever I try to run Classifer.py:

Process Process-1:
Traceback (most recent call last):
  File "/usr/lib/python2.7/multiprocessing/process.py", line 258, in _bootstrap
    self.run()
  File "/usr/lib/python2.7/multiprocessing/process.py", line 114, in run
    self._target(*self._args, **self._kwargs)
  File "/vagrant/src/Classifier.py", line 41, in classifier
    scaling(dir,emo)
  File "/vagrant/src/Classifier.py", line 12, in scaling
    subprocess.call(cmd2, stdout=outfile2)
  File "/usr/lib/python2.7/subprocess.py", line 493, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1259, in _execute_child
    raise child_exception
OSError: [Errno 8] Exec format error

This occurs for both the web interface and the command line tool. It's also repeated another four times (I assume for each emotion). The scripts then hang and become unresponsive.

I think it's an issue with the output files. I'm going to try removing them and see what happens.

Hi Chris,

Thank you. Could you try running Classification.py instead of Classifier.py? It should run and ask you to provide two input directories (possibly with a warning).

Thanks, Adam

I think I've figured it out. LibSVM in the repo is a local compiled version, so it won't execute under my vagrant environment. I'll swap this for: https://packages.debian.org/squeeze/libsvn-dev

If you want to take a look for yourself the branch I'm currently working on is here: https://github.com/i-DAT/emotionannotate/tree/add-vagrant-development-env

Have got it working by installing https://packages.debian.org/wheezy/devel/libsvm-tools and tweaking the code to use those libs rather than the ones committed into the repo.
