The following ``create-document-classifier`` example begins the training process for a document classifier model. The training data file, ``training.csv``, is located at the ``--input-data-config`` tag. ``training.csv`` is a two column document where the labels, or, classifications are provided in the first column and the documents are provided in the second column. ::

    aws comprehend create-document-classifier \
        --document-classifier-name example-classifier \
        --data-access-arn arn:aws:comprehend:us-west-2:111122223333:pii-entities-detection-job/123456abcdeb0e11022f22a11EXAMPLE \
        --input-data-config "S3Uri=s3://DOC-EXAMPLE-BUCKET/" \
        --language-code en
    
Output::
