Hello World!

Learn the basics with Hello World!

At it’s core ImagePypelines is just a way to string functions and algorithms together.

import imagepypelines as ip
@ip.blockify(void=True)
def print_msg(msg):
    print(msg)

tasks = {'msg':ip.Input(),
         'null':(print_msg, 'msg')}


msg_printer = ip.Pipeline(tasks)

We can do this by calling process directly…

processed = msg_printer.process(["Hello World!"])

# Or we can do this more naturally!
processed = msg_printer(["Hello World... but callable!"])

Out:

Hello World!
Hello World... but callable!

We can pass in any data we want! In this example, we call this function once for every datum passed in

processed = msg_printer.process(['we','can','print','anything','individually!'])

Out:

we
can
print
anything
individually!

We can also print everything at once with the batch_type variable

@ip.blockify(batch_type="all", void=True)
def print_all(msg):
    print(msg)

tasks = {'msg':ip.Input(),
         'null':(print_all, 'msg')}
print_all_pipeline = ip.Pipeline(tasks)

processed = print_all_pipeline.process(['we','can','print','everything','at','once!'])

Out:

['we', 'can', 'print', 'everything', 'at', 'once!']
