Textblob not finding the downloaded corpora

[cagan-elden]

python -m textblob.download_corpora

Although I download the corpora as said in the error message it still does not work.
I ain't sure is it because of the NLTK library or not because I've installed that too.

I found upgrading from NLTK 3.8.1 to 3.9.1 broke my project. I now get errors asking me to:

python -m textblob.download_corpora

Previously you could download textblob corpora on one account and it could be found by another account. This is no longer the case.

Moving back to NLTK 3.8.1 fixed it. I can reproduce the issue by upgrading to 3.9.1 again.

The problem is due the version moving back to the NLTK 3.8.1 can help to rectify the error

To follow up on this, I fixed it by specifying the NLTK data path and telling NLTK where to look like this:

def download_nltk_resources(self):
    """
    Downloads required NLTK resources if not already present.
    """
    import nltk
    import os
    
    # Use the environment variable or fall back to default
    nltk_data_path = os.getenv('NLTK_DATA', '/usr/local/share/nltk_data')
    
    # Ensure the directory exists
    os.makedirs(nltk_data_path, exist_ok=True)
    
    # Add our path to NLTK's data path
    nltk.data.path.insert(0, nltk_data_path)
    
    print(f"Using NLTK data path: {nltk_data_path}")
    
    required_resources = {
        'averaged_perceptron_tagger': ('taggers', 'averaged_perceptron_tagger'),
        'averaged_perceptron_tagger_eng': ('taggers', 'averaged_perceptron_tagger_eng'),
        'punkt': ('tokenizers', 'punkt'),
        'punkt_tab': ('tokenizers/punkt_tab', 'english'),
        'movie_reviews': ('corpora', 'movie_reviews'),
        'brown': ('corpora', 'brown'),
        'conll2000': ('corpora', 'conll2000'),
        'wordnet': ('corpora', 'wordnet')
    }
    
    # Download and verify all resources
    for resource, (folder, name) in required_resources.items():
        try:
            nltk.data.find(f'{folder}/{name}')
        except LookupError:
            print(f"Downloading {resource}...")
            nltk.download(resource, download_dir=nltk_data_path, quiet=True)

with NLTK_DATA specified as an environment variable.

Then do something like this:

try:
    # Download resources only once at the start
    if not hasattr(TextParser, '_resources_checked'):
        self.download_nltk_resources()
        TextParser._resources_checked = True

How to solve this issue?

[Ajaychaki2004]

Moving back to NLTK 3.8.1 fixed it. I can reproduce the issue by upgrading to 3.9.1 again.
By downgrading the NLTK you can solve the issue.

Just be aware NLTK <3.9 contains a critical security vulnerability so you're better off specifying the data path like I suggested rather than using an older insecure version.

[Ajaychaki2004]

Can you tell the solution in detail ??
