some widgets are missing

Postby millim » Tue May 20, 2014 10:23

Hi,

I came across orange data mining. I have downloaded the current version (2.7.5.dev-unknown) on windows 7. After successful installation I have seen that some widgets are missing. For example in the Visualize tab I see only: Attribute-Statistics, Mosaic Display, Sieve Diagram, and Venn-Diagram. All useful widgets are missing!
Option->Show Output View is empty.

This usually indicates a missing or incompatible PyQwt library.
Did you have a prior installation of Python and PyQt4 before installing Orange? Try uninstalling PyQwt5 and PyQt4 (make sure that "C:\Python27\Lib\site-packages\PyQt4" directory has been deleted, if not delete it manually), then rerun the Orange installer and install both PyQt4 and PyQwt5 when prompted.
