Hi All,

I am trying to create some tool for houdini with pyqt and for some reason pyqt import is not happening

here is output from houdini



Python 2.6.4 (r264:75706, Dec 7 2009, 18:59:58)
on linux2
Houdini 11.1.22 hou module imported.
Type “help”, “copyright”, “credits” or “license” for more information.
>>> import houdini_remap
>>> Exception in thread Thread-1:

from PyQt4 import QtCore
ImportError: /usr/lib/pymodules/python2.6/PyQt4/QtCore.so: undefined symbol: _Py

and here is the output from python shell


Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41)

>>> from PyQt4 import QtCore

I can see there is python version change 2.6.4 and 2.6.5 . I s that make a big difference if thats the case then how I can resolve this issue ?

Thanks a lot

i think u shoud get a 2.6.4 and install pyqt to …\Side Effects Software\Houdini xx.xxx\python26\lib\site-packages

Thanks xarchx I will try that . But Is there any way I can change the python version in houdini ?

Thanks

Hi All,

hey Achayan, I am have the same problem when I am importing QtGui from PyQT4. import PyQt4 is without errors but the QtGui gives the same error as with you. How did you fixed it, which version of pyqt you installed? Houdini in my machine uses its own python 2.6.4 and not system's 2.6.7 but I am calling pyqt4 from system's python and maybe thats the problem. Did you installed pyqt inside houdini or did you installed 2.6.4 in your system as well and pyqt again?
