AttributeError: 'CountVectorizer' object has no attribute 'get_feature_names'

This error occurs when a method or attribute is called on an object that does not have that specific method or attribute. In this case, the error message indicates that the 'get_feature_names' method is being called on a CountVectorizer object, but that method does not exist for that object.
One possible solution is to check if the CountVectorizer object has been properly initialized and trained on data. Another solution is to use a different method or attribute that is available for the CountVectorizer object.
For example, instead of using 'get_feature_names', you can use the 'vocabulary_' attribute to get a dictionary of the feature names and their indices:
```
vectorizer = CountVectorizer()
X = vectorizer.fit_transform(text_data)
feature_names = vectorizer.vocabulary_
```
This will return a dictionary where the keys are the feature names and the values are the corresponding indices in the feature matrix.
