NLP - Topic Modeling
You run the code:
topics = ldamodel.show_topics(num_topics=2, num_words=3, formatted=False)

and get an error: TypeError: show_topics() got an unexpected keyword argument 'formatted'.
What is the correct way to retrieve topics without formatting in Gensim?
AReplace <code>show_topics</code> with <code>print_topics</code> and keep <code>formatted=False</code>
BUse <code>ldamodel.show_topics(num_topics=2, num_words=3, formatted=True)</code> or omit the <code>formatted</code> argument
CUpdate Gensim to the latest version to support <code>formatted</code>
DUse <code>ldamodel.get_topics(num_topics=2, num_words=3)</code> instead
Step-by-Step Solution
Solution:
  1. Step 1: Understand the error

    The show_topics method in some Gensim versions does not accept the formatted argument.
  2. Step 2: Correct usage

    Either omit formatted or set it to True (default). To get unformatted topics, use print_topics() instead.
  3. Final Answer:

    Use ldamodel.show_topics(num_topics=2, num_words=3, formatted=True) or omit formatted -> Option B
  4. Quick Check:

    Check method signature in Gensim docs [OK]
Quick Trick: show_topics may not support 'formatted' argument [OK]
Common Mistakes:
MISTAKES
  • Assuming all versions support 'formatted' in show_topics
