• SensiML Python Client: Allows programmatic access to the REST API services through Jupyter Notebooks

Piccolo AI is currently optimized for the classification of time-series sensor data. Common use cases enabled by Piccolo AI include:

• Acoustic Event Detection
• Activity Recognition
• Gesture Detection
• Anomaly Detection
• Keyword Spotting
• Vibration Classification

To learn more about Piccolo AI features and capabilities, see the product page.

Get Started

The simplest way to get started learning and using the features in Piccolo AI is to sign up for an account on SensiML's managed SaaS service at SensiML Free Trial.

If you prefer to install and manage Piccolo AI yourself, you can get the latest version on github.

Run Piccolo AI Locally

To try out Piccolo AI on your machine, we recommend using Docker.

Prerequisites

1. Install and start docker and docker-compose - https://docs.docker.com/engine/

   • Note: Windows users will need to use the wsl2 backend. Follow the instructions here
   • Note: If using Docker Desktop go to Preferences > Resources > Advanced and set Memory to at least 12GB.

2. Follow the post-installation instructions as well to avoid having to run docker commands as sudo user

3. Some functionality requires calling docker from within docker. To enable this, you will need to make the docker socket accessible to docker containers

   sudo chmod 666 /var/run/docker.sock
   

4. By default the repository does not include docker images to generate model/compiler code for devices. You'll need to pull docker images for the compilers you want to use. See docker images:

   docker pull sensiml/sml_x86_generic:9.3.0-v1.0
   docker pull sensiml/sml_armgcc_generic:10.3.1-v1.0
   docker pull sensiml/sml_x86mingw_generic:9.3-v1.0
   docker pull sensiml/sensiml_tensorflow:0a4bec2a-v4.0
   

5. Make sure you have the latest sensiml base docker image version. If not, you can do a docker pull

   docker pull sensiml/base
   

Start Piccolo AI

1. Make sure docker is running by checking your system tray icons. If it is not running then open Docker Desktop application in Windows to start the docker background service.

2. Open a Ubuntu terminal through Windows Subsystem for Linux

   git clone https://github.com/sensiml/piccolo
   cd piccolo
   

3. Use docker compose to start the services

   docker compose up
   

Login via the Web UI Interface

Go to your browser at http://localhost:8000 to log in to the UI. See the Getting Started Guide to get started.

The default username and password is stored in the src/server/datamanager/fixtures/default.yaml file

username: [email protected]
password: TinyML4Life

Data Studio

The Data Studio is SensiML's standalone Data Capture, Labeling, and Machine Learning Model testing application. It is a companion application to Piccolo AI, but it requires a subscription to use with your local Piccolo AI.

Upgrades

Upgrades will need to check out the latest code and run database.intialize container script which will perform any migrations. You may also need to pull the newest sensiml/base docker image in some cases when the underlying packages have been changed.

Documentation
