Tutorial - classification tree

Postby sandorh » Mon Jul 14, 2014 10:23


I selected the classification tree from tutorial optinos (under Windows 7, 64 bit, Orange Canvas version is 2.7.6).
The following error message appeared at the output window:

AttributeError Traceback (most recent call last):
File "C:\Python27\lib\site-packages\Orange\OrangeCanvas\scheme\", line 380, in eventFilter
File "C:\Python27\lib\site-packages\Orange\OrangeWidgets\Utilities\", line 160, in onDeleteWidget
if self.reply.isOpen():
AttributeError: 'NoneType' object has no attribute 'isOpen'

What was wrong?

The error is actually from the 'BMC Workshop' tutorial (I will fix the error).
Just restart Orange and try again.
