Installation
=============

pvops is tested on Python versions 3.8, 3.9, 3.10, and 3.11 and depends on a variety of
packages.

The latest release of pvops is accessible via PYPI using the following
command line prompt::

    $ pip install pvops

Alternatively, the package can be installed using github::

    $ git clone https://github.com/sandialabs/pvOps.git
    $ cd pvops
    $ pip install .

NLTK data
----------

Functions in the text package rely on the "punkt_tab" dataset from the nltk package.
After proper installation of pvops, run the commands::
    
    >>> import nltk
    >>> nltk.download('punkt_tab')
    >>> nltk.download('stopwords')
