ImportError: No module named _ffnet

[Anonymous]

Hi.
On Ubuntu I've successfuly compiled the ffnet from source, but when trying to start the tests:

  warnings.warn(msg, DeprecationWarning)
/usr/lib/pymodules/python2.6/networkx/generators/hybrid.py:16: DeprecationWarning: the sets module is deprecated
  import sets
Traceback (most recent call last):
  File "./pokus.py", line 3, in <module>
    from ffnet._tests import runtest
  File "/home/orwen/bin/ffnet-0.6.2/ffnet.py", line 17, in <module>
    from fortran import _ffnet as netprop
  File "/home/orwen/bin/ffnet-0.6.2/fortran/__init__.py", line 5, in <module>
    import _ffnet, _pikaia 
ImportError: No module named _ffnet

Does Anybody have a clue why the moodule could not be imported?

I'm running it from ~/bin/ffnet-0.6.2 and there ARE right modules in ~/bin/ffnet-0.6.2/fortran:
$ ls fortran
ffnet.f  __init__.py  __init__.pyc  pikaia.f

You'd better do not try to import ffnet being in ffnet directory. Instead add ffnet dir to PYTHONPATH and import it from another place.

Just got it working: Open numpy-MKL-1.7.1.win32-py2.6.‌exe (1) with a zip program, e.g. WinRAR, and extract PLATLIB\numpy\core*.dll to the ffnet\fortran directory

As suggested, I added the ffnet dir. path to PYTHONPATH, and the problem of "ImportError: No module named ffnet " still hasn't solved.
I added the path "E:\ffnet-0.8.3\ffnet" to PYTHONPATH.
I also wish to add here that I used "gfortran" for compiling the code.
Any help please.

Is this error about 'ffnet' or '_ffnet'?

If 'ffnet' then it seems your paths are still wrong. If the second one your compilation is not working properly.

On Windows you'd better try to install precompiled package from sourceforge or from https://www.lfd.uci.edu/~gohlke/pythonlibs/ffnet.
