I am doing some data preparation for my deep learning model. In fact, I am using Orange to do text mining. 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 get an error:
Message: "Error calling '%s' of '%s'" Arguments: ('set_data', 'Topic Discovery')
Can you tell me what am I doing wrong there?
