Add additional tasks to your pipelines
======================================


.. code-block:: default

    import numpy as np
    import imagepypelines as ip

    @ip.blockify()
    def add1(a, b):
        return a+1, b+1

    @ip.blockify()
    def subtract1(a, b):
        return a-1, b-1

    @ip.blockify()
    def average(x1, x2):
        return (x1 + x2) / 2








Our Example Pipeline
--------------------
don't pay too much attention to this, we're just creating a random meaningless
pipeline


.. code-block:: default


    pipeline = ip.Pipeline({
                            'a': ip.Input(0),
                            'b': ip.Input(1),
                            ('a_plus_1','b_plus_1') : (add1, 'a', 'b'),
                            ('a_minus_1','b_minus_1') : (subtract1, 'a', 'b'),
                            }
                            )








Just call the pipeline's `update` function
------------------------------------------


.. code-block:: default


    more_tasks = {
                'average_a': (average,'a_plus_1','a_minus_1'),
                'average_b': (average,'b_plus_1','b_minus_1'),
                 }

    pipeline.update(more_tasks)








Let's process some data!
------------------------


.. code-block:: default


    # Let's create the inputs
    a = [10]
    b = [-10]

    # process
    processed = pipeline.process(a,b)

    # and check
    assert processed['average_a'][0] == a[0]
    assert processed['average_b'][0] == b[0]
