agentMET4FOF 0.4.0

A software package for the integration of metrological input into an agent-based system for the consideration of measurement uncertainty in current industrial manufacturing processes.

Multi-Agent System for Metrology for Factory of the Future (Met4FoF) Code

This is supported by European Metrology Programme for Innovation and Research (EMPIR) under the project Metrology for the Factory of the Future (Met4FoF), project number 17IND12. (https://www.ptb.de/empir2018/met4fof/home/)

About

• How can metrological input be incorporated into an agent-based system for addressing uncertainty of machine learning in future manufacturing?
• Includes agent-based simulation and implementation
• Readthedocs documentation is available at (https://agentmet4fof.readthedocs.io)

Use agentMET4FOF

The easiest way to get started with agentMET4FOF is navigating to the folder in which you want to create a virtual Python environment (venv), create one based on Python 3.8, activate it, then install agentMET4FOF from PyPI.org and then work through the tutorials or examples.

Create a virtual environment on Windows

In your Windows PowerShell execute the following to set up a virtual environment in a folder of your choice and execute the first tutorial.

PS C:> cd C:\LOCAL\PATH\TO\ENVS
PS C:\LOCAL\PATH\TO\ENVS> py -3 -m venv agentMET4FOF_venv
PS C:\LOCAL\PATH\TO\ENVS> agentMET4FOF_venv\Scripts\activate
(agentMET4FOF_venv) PS C:\LOCAL\PATH\TO\ENVS> python -m pip install --upgrade pip agentMET4FOF
Collecting agentMET4FOF

Create a virtual environment on Mac and Linux

In your terminal execute the following to set up a virtual environment in a folder of your choice and execute the first tutorial.

$ cd /LOCAL/PATH/TO/ENVS
$ python3 -m venv agentMET4FOF_venv

Inspect dashboard

Now you can visit http://127.0.0.1:8050/ with any Browser and watch the SineGenerator agent you just spawned.

To get some insights and really get going please visit agentMET4FOF.readthedocs.io .

Get started developing

First clone the repository to your local machine as described here. To get started with your present Anaconda installation just go to Anaconda prompt, navigate to your local clone

cd /LOCAL/PATH/TO/agentMET4FOF

and execute

conda env create --file environment.yml 

This will create an Anaconda virtual environment with all dependencies satisfied. If you don't have Anaconda installed already follow this guide first, then create the virtual environment as stated above and then proceed.

Alternatively, for non-conda environments, you can install the dependencies using pip

pip install -r requirements.txt

First take a look at the tutorials and examples or start hacking if you already are familiar with agentMET4FOF and want to customize your agents' network.

Alternatively, watch the tutorial webinar here

Updates

• Implemented base class AgentMET4FOF with built-in agent classes DataStreamAgent, MonitorAgent
• Implemented class AgentNetwork to start or connect to a agent server
• Implemented with ZEMA prognosis of Electromechanical cylinder data set as use case
• Implemented interactive web application with user interface

Orphaned processes

In the event of agents not terminating cleanly, you can end all Python processes running on your system (caution: the following commands affect all running Python processes, not just those that emerged from the agents).

Killing all Python processes in Windows

In your Windows command prompt execute the following to terminate all python processes.

> taskkill /f /im python.exe /t
>

Killing all Python processes on Mac and Linux

In your terminal execute the following to terminate all python processes.

$ pkill python
$
