The acumos_model_runner package installs a command line tool acumos_model_runner for running models created by the Acumos Python client library <https://pypi.org/project/acumos/>__.
The model runner provides an HTTP API for invoking model methods, as well as a Swagger UI <https://swagger.io/tools/swagger-ui/>__ for documentation. See the tutorial for more information on usage.
You will need a Python 3.4+ environment in order to install acumos_model_runner.
You can use Anaconda <https://www.anaconda.com/download/>__
(preferred) or pyenv <https://github.com/pyenv/pyenv>__ to install and
manage Python environments.
The acumos_model_runner package can be installed with pip:
.. code:: bash
$ pip install acumos_model_runner
.. code:: bash
usage: acumos_model_runner [-h] [--host HOST] [--port PORT]
[--workers WORKERS] [--timeout TIMEOUT]
[--cors CORS]
model_dir
positional arguments:
model_dir Directory containing a dumped Acumos Python model
optional arguments:
-h, --help show this help message and exit
--host HOST The interface to bind to
--port PORT The port to bind to
--workers WORKERS The number of gunicorn workers to spawn
--timeout TIMEOUT Time to wait (seconds) before a frozen worker is
restarted
--cors CORS Enables CORS if provided. Can be a domain, comma-
separated list of domains, or *

This tutorial demonstrates how to use the Acumos Python model runner with an example model.
An Acumos model must first be defined using the Acumos Python client library <https://pypi.org/project/acumos/>__. For illustrative purposes, a simple model with deterministic methods is defined below.
.. code:: python
# example_model.py
from collections import Counter
from acumos.session import AcumosSession
from acumos.modeling import Model, List, Dict
def add(x: int, y: int) -> int:
'''Adds two numbers'''
return x + y
def count(strings: List[str]) -> Dict[str, int]:
'''Counts the occurrences of words in `strings`'''
return Counter(strings)
model = Model(add=add, count=count)
session = AcumosSession()
session.dump(model, 'example-model', '.')
Executing example_model.py results in the following directory:
.. code:: python
.
├── example_model.py
└── example-model
Now the acumos_model_runner command line tool can be used to run the saved model.
.. code:: bash
$ acumos_model_runner example-model/
[2018-08-08 12:16:57 -0400] [61113] [INFO] Starting gunicorn 19.9.0
[2018-08-08 12:16:57 -0400] [61113] [INFO] Listening at: http://0.0.0.0:3330 (61113)
[2018-08-08 12:16:57 -0400] [61113] [INFO] Using worker: sync
[2018-08-08 12:16:57 -0400] [61151] [INFO] Booting worker with pid: 61151
The model HTTP API can be explored via its generated Swagger UI. The Swagger UI of example-model above can be accessed by navigating to http://localhost:3330 in your web browser.
Below are some screenshots of the Swagger UI for example-model.
The Swagger UI enumerates model method APIs, as well as APIs for accessing model artifacts. Below, the APIs corresponding to the add and count methods are listed under the methods tag.
|Model APIs|
.. |Model APIs| image:: https://gerrit.acumos.org/r/gitweb?p=python-model-runner.git;a=blob_plain;f=docs/tutorial/example-model-apis.png;hb=HEAD
Expanding the documentation for the count method reveals more information on how to invoke the API.
|Model Method|
.. |Model Method| image:: https://gerrit.acumos.org/r/gitweb?p=python-model-runner.git;a=blob_plain;f=docs/tutorial/example-model-method.png;hb=HEAD
The Swagger UI provides an input form that can be used to try out the count API with sample data.
|Model Method Request|
.. |Model Method Request| image:: https://gerrit.acumos.org/r/gitweb?p=python-model-runner.git;a=blob_plain;f=docs/tutorial/example-model-request.png;hb=HEAD
The response from the count API shows that everything is working as expected!

We use a combination of tox, pytest, and flake8 to test
acumos_model_runner. Code which is not PEP8 compliant (aside from E501) will be
considered a failing test. You can use tools like autopep8 to
“clean” your code as follows:
.. code:: bash
$ pip install autopep8
$ cd python-model-runner
$ autopep8 -r --in-place --ignore E501 acumos_model_runner/ testing/ examples/
Run tox directly:
.. code:: bash
$ cd python-model-runner
$ tox
You can also specify certain tox environments to test:
.. code:: bash
$ tox -e py34 # only test against Python 3.4
$ tox -e flake8 # only lint code
And finally, you can run pytest directly in your environment (recommended starting place):
.. code:: bash
$ pytest
$ pytest -s # verbose output
