This HTM Engine application was built from the Skeleton HTM Engine App. It is like a scaffolding with an HTM Engine ready to run after a few configuration changes. It is the place to start if you want to create a new HTM Engine application. See its README for more details.

Setup

1. Install and Start Required Services

Install the following services appropriately for your environment:

Go ahead and start the MySQL server and RabbitMQ, but not Supervisor.

2. Install HTM Engine and NTA Utils

Clone https://github.com/numenta/numenta-apps locally.

You'll need to install nta.utils, which is a dependency of htmengine:

cd numenta-apps/nta.utils
python setup.py develop --user

Then you can install htmengine in development mode:

cd numenta-apps/htmengine
python setup.py develop --user

3. Install Required Python Modules

Now, back in your htmengine-traffic-tutorial directory:

pip install -r python-engine/requirements.txt

4. Set APPLICATION_CONFIG_PATH in your environment

The APPLICATION_CONFIG_PATH environment variable must be set, and point to the htmengine-traffic-tutorial/python-engine/conf/ directory. For example, if you're in the the htmengine-traffic-tutorial directory:

export APPLICATION_CONFIG_PATH=`pwd`/python-engine/conf

5. Create a MySQL database

For this tutorial, we'll be using a database called traffic:

mysql -u root --execute="CREATE DATABASE traffic"

6. Apply database migrations

This will set up the traffic database by creating the appropriate table schema for the application.

Again, from the htmengine-traffic-tutorial directory:

python python-engine/repository/migrate.py

7. Update Two Config Files

In python-engine/conf/supervisord.conf, there are two places where absolute paths need to be updated. Look for the string /Users/mtaylor/nta/ and replace with your local path to your htmeengine-traffic-tutorial checkout.

In python-engine/conf/model-checkpoint.conf, update the storage.root value to point to a directory within your own file system. If this folder does not exist, it will be created.

8. Start services with supervisor

This time, you must be in the htmengine-traffic-tutorial/python-engine directory:

cd python-engine
mkdir logs
supervisord -c conf/supervisord.conf

At this point, the core htmengine services are running. You can see the supervisor status at http://localhost:9001/ or by running supervisorctl status.

To stop supervisord services, run supervisorctl stop all.

Continue

The HTM Engine server is now running. You may now continue setup within the primary README of this repository.
