ImportError: No module named qwt_thermo

Hello everyone

Im using Ubuntu 12.04 and creating my .ui with Qt Designer with Python 2.7.

My problem is when I want to put some Qwt Widgets, for example: QwtThermo.

On my code I have import:

from PyQt4.Qt import *
from PyQt4.Qwt5 import *

and downloaded from ubuntu software Qt widgets library.

File "/opt/ros/hydro/lib/python2.7/dist-packages/python_qt_binding/binding_helper.py", line 257, in loadUi
return _loadUi(uifile, baseinstance, custom_widgets)

I'dont know whats wrong
Thanks for your time.

Have you installed both the Qwt library and the PyQwt package?

I installed : PyQwt-4.2.3 and when install Qwt library i put : CONFIG+=qwt on my qwt.pro file.
and on my bashrc the line: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/Desktop/qwt/qwt-6.0.1/lib/

Added after 6 minutes:

qwt.pro file.

What does the Qwt pro file have to do with it?

Exactly which version of Ubuntu? Exactly which packages? The chances seem good that the bindings you have for Python are linked against a particular Qwt 5 version (probably 5.2.1).
