How to disable nltk_data command line output?

Hi. I’m developing a chatbot with this library. I was wondering if there’s any way to suppress the output to the command line related to nltk_data every time I run my program. I am talking about this:

[nltk_data] Downloading package averaged_perceptron_tagger to
[nltk_data]     /home/sgeor/nltk_data...
[nltk_data]   Package averaged_perceptron_tagger is already up-to-
[nltk_data]       date!
[nltk_data] Downloading package punkt to /home/sgeor/nltk_data...
[nltk_data]   Package punkt is already up-to-date!
[nltk_data] Downloading package stopwords to /home/sgeor/nltk_data...
[nltk_data]   Package stopwords is already up-to-date!

I am using flask for the frontend of my app and every time the server is restarted (or I run any of the flask do_something commands I have implemented) this appears in the console.

Thanks.

1. cd to C:\Users\YOUR_USER_NAME\AppData\Roaming\nltk_data or venv/nltk_data or where nltk_data is downloaded…
2. copy nltk_data/corpora/stopwords to nltk_data/stopwords
3. copy nltk_data/taggers/averaged_perceptron_tagger to nltk_data/averaged_perceptron_tagger

Before:

After:

In version 1.0.5, chatterbot/utils.py has four download_nltk_xxx functions:

def download_nltk_stopwords():
    """
    Download required NLTK stopwords corpus if it has not already been downloaded.
    """
    nltk_download_corpus('stopwords') # should be 'corpora/stopwords'


def download_nltk_wordnet():
    """
    Download required NLTK corpora if they have not already been downloaded.
    """
    nltk_download_corpus('corpora/wordnet')


def download_nltk_averaged_perceptron_tagger():
    """
    Download the NLTK averaged perceptron tagger that is required for this algorithm
    to run only if the corpora has not already been downloaded.
    """
    nltk_download_corpus('averaged_perceptron_tagger') # should be 'taggers/averaged_perceptron_tagger'


def download_nltk_vader_lexicon():
    """
    Download the NLTK vader lexicon for sentiment analysis
    that is required for this algorithm to run.
    """
    nltk_download_corpus('vader_lexicon')

They all call the function nltk_download_corpus, whose parameter resource_path represents the path to check if the data exists.

In an upcoming release, I’d be happy to add an option that makes it possible to disable this output.
