ffnet 0.8.0 Python 3.4.2 windows 8.1

[Andre Smolentzov]

I have installed ffnet 0.8.0 on Windows 8.1. I dowloaded ffnet throug "Christoph Gohlke, Laboratory for Fluorescence Dynamics, University of California, Irvine" windows binaries. I am getting the following errors when running the testcases, I get many test cases correct but I am getting two errors:
ERROR1:

testExportNoDerivative (ffnet._tests.TestSaveLoadExport) ... Could not locate executable C:Python34pythonw.exe
Executable C:Python34pythonw.exe does not exist

ERROR

Then I got a bunch of "ok test cases.

ERROR2:

ERROR: testExportNoDerivative (ffnet._tests.TestSaveLoadExport)

Traceback (most recent call last):
File "C:\Python34\lib\site-packages\ffnet_tests.py", line 385, in testExportNoDerivative
import tmpffnet2
ImportError: No module named 'tmpffnet2'

I have the latest scipy and numpy (scipy 0.16.0 and numpy 1.10.0b1).
Any ideas about this problem?

I have no problems to invoke the pythonw.exe to start the idle. For example the following command triggers the idle without problems:
C:\Python34>pythonw.exe c:\Python34\Lib\idlelib\idle.py
No problem to invoke the following: C:>C:Python34/pythonw.exe

Hi!

It seems like the problem with f2py which cannot locate python executable necessary for these two test cases (where are backssashes in the path?!):

locate executable C:Python34pythonw.exe
Executable C:Python34pythonw.exe does not exist

If ffnet works normally for you i would not bother about these errors, unless you export the networks to Fortran and compile them...
