• In this modified code, the spacy_version variable is used to store the version of the SpaCy library. Inside the loop, the code checks whether the SpaCy version is 3.0.0 or higher. If it is, the lemmatization is performed using nlp(combined_texts). Otherwise, for older versions, the lemmatization is done using nlp.tokenizer(combined_texts). This change accounts for potential differences in SpaCy versions and ensures the code can handle them correctly.
