possible to install this agent the old fashion way?

[bbartling]

Can I install the agent with scripts/install-agent.py just to get up and running for testing purposes?

python scripts/install-agent.py -s examples/volttron-openadr-ven/ -c examples/volttron-openadr-ven/volttron_openadr_ven/config.json --tag openadr_agent

I git cloned the repo, and put in a config.json for the VEN name and VTN server URL.

I just get an error pertain to there is no setup.py and I think this is because agents to be installed new way, like a PyPi method?

Without knowing what I am doing I just gabbed the CSV driver setup.py, changed James Larson to Mark, and copied it into the repo where I am running VOLTTRON on my test bench.

But when I install the agent with install-agent.py, large errors:

Thanks for anytime in response getting this up and running.

This is also the setup.py below

from setuptools import setup, find_packages

MAIN_MODULE = 'agent'

# Find the agent package that contains the main module
packages = find_packages('.')
agent_package = 'volttron_openadr_ven'

# Find the version number from the main module
agent_module = agent_package + '.' + MAIN_MODULE
_temp = __import__(agent_module, globals(), locals(), ['__version__'], 0)
__version__ = _temp.__version__

# Setup
setup(
    name=agent_package + 'agent',
    version=__version__,
    author="Mark Bonicillo",
    author_email="mark.bonicillo@pnnl.gov",
    description="Agent for demonstrating reading values from a device and actuating the device",
    install_requires=['volttron'],
    packages=packages,
    entry_points={
        'setuptools.installation': [
            'eggsecutable = ' + agent_module + ':main',
        ]
    }
)

And config.json below

{
    "ven_name": "dan_test",
    "vtn_url": "http://123.123.234.345:8080/OpenADR2/Simple/2.0b"
}

This agent will need the interface from the client and utils wheels in order to run. You can build your agent using poetry build and then install that wheel through the "old" way....I haven't done this, however it should be doable. You may have to add the config to it using vpkg however.

Any chance I could get a tip for the error in the steps I am doing? Is starting up VOLTTRON the old fashion way a thing of the past if we are using Poetry as virtual environment and dependency management?

For example with my very limited experience using VOLTTRON I would only do this in the volttron directory that I git cloned:

volttron$ source env/bin/activate ./start-volttron

I think I am doing something wrong with the poetry virtual environment and trying to also start volttron in my old way of starting volttron with the virtual environment. No matter what way I am trying I am having some issues.

Without doing any of the steps above of the old fashion way of starting volttron, if I do this:

1. Then cd directory to where I git cloned this open ADR repo in the volttron/examples/volttron-openadr-ven directory on my Ubuntu 20.04 test machine.

Run these poetry steps:

poetry shell NOTE: Poetry needs the command 'python' in order to create a new shell. On Linux, if you only have python3 installed, run the following to link 'python' to 'python3':

$ sudo apt install python-is-python3 Install requirements (env) $ poetry install Install Volttron-specific dependencies for this agent. (env) $ pip install volttron_utils-0.1.1-py3-none-any.whl volttron_client-0.1.2-py3-none-any.whl

I did notice one error on the build of all of this the first time it ran but seems fine on the second time.

I am in this directory now with the poetry virtual environment (volttron-openadr-ven-jMgY9TEO-py3.8) dan@lt-ubuntu:~/Desktop/volttron/examples/volttron-openadr-ven$

change directory back to volttron.

dan@lt-ubuntu:~/Desktop/volttron$ ./start-volttron

This will fail to start volttron.

Starting VOLTTRON verbosely in the background with VOLTTRON_HOME=/home/dan/.volttron
Waiting for VOLTTRON to startup..
VOLTTRON startup failed/timed out. Please check volttron.log for details
(volttron-openadr-ven-jMgY9TEO-py3.8) dan@lt-ubuntu:~/Desktop/volttron$

doing a less volttron.log I do see this:

During handling of the above exception, another exception occurred:

So the way this will work is you have two environments. One for the agent itself and one for the platform. As long as you are running the platform i.e. at 22916 port this should work... I will soon send guidance on how to make agents behave on local platforms from repositories. Should be by monday on this.

[bbartling]

Any further development on this? : )
