I'm trying to get used to text mining using orange. I set up a very easy workflow loading a corpus (tab separated text file containing 10 entries), using a corpus viewer that shows my data correctly and a topic discovery item. But I always receive an error Message at 95% of topic discovery called:
Message: "Error calling '%s' of '%s'" Arguments: ('set_data', 'Topic Discovery')
What do you think am I doing wrong here? Thank you very much for your help in advance.
