LookupError in NLTK for WordNet Lemmatizer Despite Successful Download of Resources

Question

I am working on a text processing task in a Kaggle notebook and facing a LookupErrorwhen using NLTK's WordNetLemmatizer. Despite my efforts to download the required NLTK resources, the error continues to occur. Below, I have provided the details of my preprocessing function, the error message, and the steps I've taken to resolve the issue.

Preprocessing Function:

def preprocess_str_ml(txt):
    tokenizer = TweetTokenizer()
    lemmatizer = WordNetLemmatizer()
    
    # convert all characters in the string to lower case
    txt = txt.lower()
    # remove non-english characters, punctuation and numbers
    txt = re.sub('[^a-zA-Z]', ' ', txt)
    
    # Tokenize the text
    tokens = tokenizer.tokenize(txt)

    # Lemmatization and removing stop words
    lemmatized_tokens = [lemmatizer.lemmatize(token) for token in tokens]
    
    txt = ' '.join(lemmatized_tokens)
    
    txt = remove_stop_words(txt)
    
    return txt

Error Message:

LookupError                               Traceback (most recent call last)

1. I have tried downloading the complete NLTK package using nltk.download("all").
2. I also attempted downloading the "averaged_perceptron_tagger", as some forums suggested. These attempts were made within a Kaggle notebook environment.Despite these efforts, the error remains unresolved.

How can I effectively resolve this LookupErrorin the Kaggle notebook environment? Are there additional steps or configurations required for setting up NLTK for lemmatization with the WordNet Lemmatizer in Kaggle?
