NLP - Topic Modeling

You run the following code and get an error:

ldamodel = gensim.models.LdaModel(corpus, num_topics=3, id2word=dictionary, passes=5)
print(ldamodel.print_topics())

The error says: TypeError: print_topics() missing 1 required positional argument: 'num_topics'
What is the fix?

AAdd <code>num_topics</code> argument like <code>print_topics(num_topics=3)</code>

BRemove <code>num_topics</code> from LdaModel constructor

CCall <code>print_topics()</code> without arguments

DUse <code>show_topics()</code> instead

Step-by-Step Solution

Solution:

Step 1: Understand the error message
The error says print_topics() requires the number of topics to print as an argument.
Step 2: Fix the method call
Pass num_topics=3 to print_topics() to specify how many topics to display.
Final Answer:
Add num_topics argument like print_topics(num_topics=3) -> Option A
