Hi.
There is a way to send the message between two agents running on the different spade platforms?
For example: spade platform with IP address1 and another spade platform with IP address2 ?
I use Linux (Ubuntu 16.04 LTS) , to get this thing I have to create two Virtual Machine?
Please tell me all that is inherent to this problem.
Thanks

Hello,

I've been using SPADE for quite a while now and it has been a great help.
But I'm facing an issue. How can an agent receive normal chat messages?
The ACL templates don't work and even in a defaultBehaviour where I can catch all the messages, there seems to be no way I could break the message into all the different parts.
It has no content, no Sender, no Performative, or Ontology.
It instead has "from", "to", "body", etc...

Is there a way to receive and interpret non FIPA messages?

Thank you

Description

For a simulation containing 100+ agents, I've been testing SPADE and xmpp servers. Currently I'm using the xmpp server "jwchat.org", chose a jid, then created multiple resources with the same jid (i think the theoretical maximum is 256 resources). It simply didn't work.

What I Did

Even when I use dummy agents (without behavior), i can't even create more than 10 or 11 of such agents. Once the number of agents exceed 10, i'll receive an error of "cancellation due to concurrency", as shown below:

LOAD1:	Agent is online!
LOAD2:	Agent is online!
LOAD3:	Agent is online!
LOAD4:	Agent is online!
LOAD5:	Agent is online!
LOAD6:	Agent is online!
LOAD7:	Agent is online!
LOAD8:	Agent is online!
LOAD9:	Agent is online!
LOAD10:	Agent is online!

(...and so on...)

Regarding this I have several questions:

[A Survey] Which xmpp server do you use personally?
What're the good features and how did you find them out?

1. Has anyone tested SPADE with large numbers of (100+) agents? Which xmpp server would you recommend for such an application? Is it possible to create even more than 256 agents on SPADE? How if yes, or why don't you recommend doing it?

2. @javipalanca once mentioned that it's possible to create one's own xmpp-server (I hope this would resolve the concurrency issues). Is there a handy tutorial (step-by-step) on how to do it? Thanks!

3. async/await issues
   In SPADE, is there a practical way to avoid "concurrent.futures._base.CancelledError"? Personally i'm not familiar with multi-threading, but I would be very grateful if you could give me (us all) some tricks to avoid it (e.g., by adding await asyncio.sleep()).
   For example, i'd like to initialize one agent that further creates a list of other agents. However, I can't add an async-sleep between the creation of two agents.

4. When printing, how to avoid concurrent prints from different agents like this (where each agent should print on separate lines):

   LOAD55: Agent is online!
   LOAD55: Agent starts the trade behaviour.
   LMO: Starts the clearLocalMarket behaviour: in 3 steps
   LMO: Step 1: LMO sends call-for-bids to prosumers.
   ch03218_Avg_kW: Received a call-for-bid from LMO.
   ch03231_Avg_kW: Received a call-for-bid from LMO.LOAD55: Received a call-for-bid from LMO.
   ch03205_Avg_kW: Received a call-for-bid from LMO.

   ch03244_Avg_kW: Received a call-for-bid from LMO.LOAD40: Received a call-for-bid from LMO.
   LOAD1: Received a call-for-bid from LMO.
   LOAD20: Received a call-for-bid from LMO.

5. In SPADE, are there any functions for an agent to search for other agents of a certain class, name, or feature? Some agent platforms like JADE provide such convenient functions, and I've been looking for a replacement of that in SPADE.

Finally, thank you all so much for making SPADE as fancy as it is!

Cheers,
Piao

Hi,
I am new to using SPADE. I have issues logging into the web interface of SPADE. Could you please tell me what password I should be using to login to the web interface?

Thank you.

I am going through the tutorials and got to the "Agent Communication: Sending and Receiving Messages" step.
In the ReceiveBehav class the line self.msg = self._receive(True, 10) is expected to block the behavior for 10 seconds and then resume. However, when I run it, nothing happens. I would expect, that given no message, the agent would print "I waited but got no message" every 10 seconds.
I checked and the behaviour enters the _process method only once. It is like there is no difference between self._receive(True, 10) and self._receive(True).

Any idea on what the problem might be? Thanks.

Hi,
I trying use the done() command to receive a return when a OneShotBehaviour( ) has finished, but I don't have success. Here an example that I did:

<--- Import behaviour from another module --->
from protocols.generic.Subscribe import SubscribeXMPP

<--- In another behaviour inside of the Agent class... --->
class SetupBehaviour(OneShotBehaviour):
        async def run(self):
        	setup = open("setup.txt","r")
            	lines = setup.readlines()
            	
                for line in lines:
                    self.agent.name = line
                    b1 = SubscribeXMPP()
                    self.agent.add_behaviour(b1)

                    print(b1.done()) 

                    while(b1.done() is False):
                        time.sleep(1)

                    print(b1.done())   

I expected that the b1.done( ) return at first False as a value, and when the behaviour are finished, his value is True. This happen, but the behaviour only execute (or print in the screen) after the alternance of this values and work only with the last line in lines.

Example

Supposing in setup.txt this lines:

agenta
agentb
agentc

and the SubscribeXMPP(OneShotBehaviour) execute a bash command to add each one of this lines as a agent connected in Prosody and after this, create a new agent in SPADE, the result is:

False
True
False
True
False 
True

Hello World! I'm agent agentc@localhost

I suspect that I don't understand the done() command exactly how he work.

Thanks in advance!

Hello there,

I'm doing my master's thesis in the area of optimizing the self-consumption of solar-powered smart micro-grids and I'm using multi-agent system to simulate energy exchange between energy consumers and producers represented by agents.
I tried to apply the BDI concept, but it seems that the BDI example and testcase are not working with me (*attached are the error messages that appear while running the Server1BDI.py, ClientBDI.py and BDItestcase.py files).. https://www.dropbox.com/s/ua7lzl4sq39obo7/BDI.zip?dl=0
Please advice!

Description

Firstly, thanks for releasing SPADE 3.0.1! Congratulations!
I have been playing with the develop version (3.0.0) and was very excited to test the stable version.
I did encounter a problem with the basic example DummyAgent.py as follows:

import spade.agent

class DummyAgent(spade.agent.Agent):
    def setup(self):
        print("Hello World! I'm agent {}".format(str(self.jid)))

dummy = DummyAgent("[email protected]", "password")

dummy.start()
dummy.stop()

What I Did

I ran this simple code on Win10/PowerShell, and on Mac/Terminal, but I got almost the same error on different platforms. It was not this case with SPADE 3.0.0.

Running the DummyAgent code from the Quick Start section of SPADE documentation causes the script to be unable to finish properly.

Code:

from spade import agent
class DummyAgent(agent.Agent):
    async def setup(self):
        print("Hello World! I'm agent{}".format(str(self.jid)))

dummy = DummyAgent("your_jid@your_xmpp_server", "your_password")

dummy.start()

dummy.stop()

Output:

Hello World! I'm agent your_jid@your_xmpp_server

Dear all,

I've been playing with the SPADE 3 "develop branch" and faced an Asyncio-related issue with Jupyter Notebook.

I simply ran the quick start example in SPADE 3 documentation Ch5.1:

import spade.agent

class DummyAgent(spade.agent.Agent):
def setup(self):
print("Hello World! I'm agent {}".format(str(self.jid)))

dummy = DummyAgent("blabla", "blabla")

dummy.start()
dummy.stop()

By "dummy.start()" Jupyter Notebook bounces back an error as follows. However, it doesn't happen if I run the .py-file using command prompt.

I want to use a speech synthesis package called pyttsx3 which offers its own event loop for the execution of the synthesis.
When using their event loop the voice output blocks everything else until I stop their event loop, which comes with a 1200ms delay.

Pyttsx3 als offers to use a custom event loop as described here.

Where would I call engine.iterate()?

Can I add Tasks or method calls to Spade's event loop?

Thank you for helping me! <3

Hi,

I installed SPADE with my server name as "localhost". Then I followed your guide and tried to run the example told on "My First SPADE agent" page (http://spade.gti-ia.dsic.upv.es/manuals/html-chunk/spade.basicagents.first.html). But when I typed "python file_name.py", the console didn't bring anything for a long time and then I got an error message saying

Hello,
I am new to SPADE and I am running the runTest.py for the auction. I can see that each bidder has some money and the auctioneer has been initialised as well. The comments in the code say the entire interaction is done via the web. Could you please tell me how I perform this auction from the web?

Thank you.

I am attempting to run an agent more than once
given a simple agent that exits on its third count how can I run the agent after it exits from another script
Suppose an agent is below:
import spade
import time
import sys
d=[]
class MyAgent(spade.Agent.Agent):
class MyBehav(spade.Behaviour.Behaviour):
def onStart(self):
print "Starting behaviour . . ."
self.counter = 0

    def _process(self):
        print "Counter:", self.counter
        self.counter = self.counter + 1
        i=self.counter
        if i==3:
            sys.exit(0)
        d.append(self.counter)
        print d
        print d[i-1]
        time.sleep(1)

def _setup(self):
    print "MyAgent starting . . ."
    b = self.MyBehav()
    self.addBehaviour(b, None)

if name == "main":
a = MyAgent("[email protected]", "secret")
a.start()

Can I add a behavior to obtain chat messages? Does SPADE work with ACL massages only?

I have installed a Prosody IM server. This works with SPADE in localhost when I configure in prosody.cfg.lua the virtualhost as 'localhost" and using a DNSmasq I can find it in a LAN using another virtualhost like 'spade.loc'.

I saw the documentation in Prosody server and found issues about SRV records, then I configure my Prosody config file inserting this information and it works.

But now, the aioxmmp show me the follow error:

aioxmpp.errors.MultiOSError: failed to connect to XMPP domain 'spade.loc': multiple errors: stream error: {urn:ietf:params:xml:ns:xmpp-streams}undefined-condition ('No stream features to proceed with')
I already have the 'smacks' mod to handler with streams, but it not works.

When i use web user interface i can`t see opponent agent message in chat box

What I Did

My issue change private function in spade/trace.py:
1 Old code:
def _agent_in_msg(agent, msg):
return msg.to == agent or msg.sender == agent

2 New code:
def _agent_in_msg(agent, msg):
return str(msg.to).startswith(str(agent)) or str(msg.sender).startswith(str(agent))

All problem is a resource in JID

Dear All,

I'm beginner with SPADE. I have used SPADE on IOS, it working well.

Now, I try to install the last version (https://github.com/javipalanca/spade/) into a Windows 10 environment.
I use python2.7 but when I execute the command "pip install SPADE" i obtain the following error:

Please could you indicate me if the last version is compatible with windows 10 ?

Thanks in advance

I think it's time to plan a new major revision of SPADE. I know there are lots of ideas to improve the platform but I think there are major refactorings that are needed before continuing the development of the platform.
The most important is the most difficult, to change the XMPP library since xmpppy has been discontinued. This affects both the agent library and the xmpp server. In fact, we need to be able to connect to ANY xmpp server (which is not possible nowadays with xmpppy).
I would like to take this moment to also go to Python 3, where we could benefit from asyncio (among others).
I wrote SPADE when I was a python newbie (more than 10 years ago) Both python and me have increased our skills since then, and that should be reflected in the code, with better performance techniques, use of design patterns, clean code, git-flow, etc.

Looking at different python XMPP libraries I think that the most affordable and interesting is SleekXMPP (https://github.com/fritzy/SleekXMPP/) which is compatible with Python 3 and seems to be up-to-date.
Since spade 3 should be compatible with any xmpp server I still like to provide a "toy" python xmpp server that works with the spade installation. Not sure if this is a good idea or we can just include any python server like Wokkel (https://wokkel.ik.nu/) in the requirements.

There will be lots of ideas to discuss (do we want the behaviors agent model again? or any other?, do we need to follow FIPA? etc...) So please start to provide your wishlist for a next-gen Agent Platform. In the meantime, a new collaborator (MiguelBellver) is going to test SleekXMPP.

Ideas, comments, volunteers...

I'm trying to integrate the spade code in flask application.
While I add some code - DummyAgent with a web interface, in the flask application app.py, the flask application running on port 8080 and the spade is not working.

But I tried with DummyAgent without a web interface. It's working correctly

from flask import Flask, render_template
from flask import redirect
from urllib.parse import urljoin
from flask_cdn import CDN
from spade import agent

app = Flask(name)

@app.route('/')
def hello_world():
return render_template("main.html")

class DummyAgent(agent.Agent):
def setup(self):
print("Hello World! I'm agent {}".format(str(self.jid)))

dummy = DummyAgent("agent1@GAYAN-SAMUDITHA", "agent1")
dummy.start()

dummy.stop()

if name == 'main':
app.run()

WITH WEB INTERFCE

from flask import Flask, render_template
from flask import redirect
from urllib.parse import urljoin
from flask_cdn import CDN
from spade import agent

app = Flask(name)

@app.route('/')
def hello_world():
return render_template("main.html")

from spade import agent

class WebAgent(agent.Agent):
def setup(self):
print("Hello World! I'm agent {}".format(str(self.jid)))

dummy = WebAgent("admin@GAYAN-SAMUDITHA", "admin")

async def hello_controller(request):
return {"number": 42}

a = WebAgent("agent1@GAYAN-SAMUDITHA", "agent1")

a.web.add_get("/hello", hello_controller, "hello.html")

a.start(auto_register=True)
a.web.start(port=10000)

if name == 'main':
app.run()

==> Not working

Hi,
Is it possible to send objects with messages.
In the documentation, I found that meta-data should be of string type, and I need to send other types.

Thanks.

Hi,
In order to run a script for SPADE initialization at linux startup the following code was included to rc.local:

  #!/bin/sh -e
  #
  # rc.local
  #
  # This script is executed at the end of each multiuser runlevel.
  # Make sure that the script will "exit 0" on success or any other
  # value on error.
  #
  # In order to enable or disable this script just change the execution
  # bits.
  #
  # By default this script does nothing.


 exec 2> /tmp/rc.local.log  # send stderr from rc.local to a log file
 exec 1>&2                      # send stdout to the same log file
 set -x

 #script to initialize the SPADE daemon
 bash start_script.sh -m running &
 ---

However, warning messages occur:
[email protected]:[spade] There is no SPADE platform at 127.0.0.1 . Agent dying... , error
[email protected]:[spade] Could not register agent [email protected] , error
[email protected]:[spade] Did not send 'unavailable' presence: 'aggregator' object has no
attribute 'roster' , warn
[email protected]:[spade] Stopping agent [email protected] , ok
---
Executing 'sudo bash /etc/rc.local' after system boot runs perfectly.

Is there any feature in rc.local which prevents running SPADE this way?
Suggestions please.

Best Regards
Jorge

Hallo,
First thanks for the windows-based spade.
I installed it and it seemed okay with me then I ran the configure.py and runspade.py according to the installation guide and I've got these messages (see attached). There is an error while establishing the connection with the platform.
Please Advice!
Thanks,
Ahmed

I have three agents: master, slave1 and slave2.
Master sends a message to slave1 and slave2 with an operation to do.
Slave1 and slave2 should run the given operation at the same time.
What I got is that slave2 start doing is task when slave1 has finished his task.
I used the basic example to exchange messages.
Am I missing something?

Allow agents to self-register using the XEP-0077 (In-band registering).
This issue is blocked until the aioxmpp library supports this XEP.

how can an agent send a data not a simple message and how load this data?

Hi,

Using a raspberry B+, for a matter of limited resources and too high memory usage I've been trying to reduce memory occupation from a program which runs SPADE.
SPADE processes in htop show the following traits:

runspade      cpu/20%      mem/8.5%    -  (1 main shell process and 47 subshells)
script        cpu/70%      mem/9.8%     -   (1 main shell process and 4 subshells)

Looking to the above data my script is using too much memory.
In this step it was not possible to determine if my script was the source of the problem.
This script runs an OneShotBehaviour, an EventBehaviour and a PeriodicBehaviour.
Isolating the OneShotBehaviour and the EventBehaviour they do not occupy memory
as expected, and each one forks the main shell process into one subshell.
The memory occupancy from the script mantains in 3% of cpu usage.
Then running the PeriodicBehaviour it occupies 70% of cpu memory.
Because the problem could be the added code itself, the code inside the Periodic behaviour was commented and the 70% of memory usage had remained.

So at this point I am blaming the Periodic Behaviour. Repeating the period 2 in 2 seconds or 5 in 5 seconds does not influence the usage.

Finnally, there are 2 questions that arise:

1. Why does runspade.py forks the shell into 47 subprocesses?threads?
2. Is it possible the Periodic Behaviour by itself occupy so much memory?
   (the while loop followed by sleep !?)

Hi guys, first let me congratulate you for this library, it is really impressive.

In short, I have a question about performance, but it is probably more an issue with the server than with SPADE itself. I am wondering if you could give me some advice nevertheless.

We are considering using SPADE for a new agent-based model that we are currently planning for air transportation. We are very interested in using SPADE, but after some initial tests, it seems that sending and receiving messages would have a high impact on the computational performance of the model.

To give you some context, we are trying to use SPADE with around 100k agents. A very quick estimation tells us that more than 3 millions messages will be sent during a single simulation. During our tests, using a local prosody server, we estimated that the time to send and receive a message was around 0.02 second, which puts around the total CPU time to 60k seconds, more than 16 hours, just for the messages. This is too much for us, unfortunately.

So my questions are the following I guess:

• Does the 0.02 second seem normal to you for the transfer time?
• Is there any way to decrease this transfer time?
• Is it mainly due to the server?
• Shall we try others?
• Do you have any advice for the server configuration?

Thanks for taking the time to read this, and keep up the good work!

When I tried to access http://localhost:8010/ browsers returned ERR_INVALID_HTTP_RESPONSE" in Chrome and in Firefox it returned the entire html code. I was wondering what part went wrong. Please advise. Thank you.

To communicate with a SPADE agent from a REST API
where and how to send information to the agent?

In the opposite stream, from the agent to the API it is not in question. I mean to send a message from the REST API that the agent receives.
What is the address to which I must send messages?
(would be interesting to understand how to use the WUI from SPADE)

Regards.

Description

Agents should be able to self-register on the XMPP server (as per #31), but both register() and start(auto_register=True) fails with aiosasl.AuthenticationFailure and spade.agent.AuthenticationFailure.

Important note: I'm yet to test it with an XMPP server hosted under a proper domain name and with a valid certificate - this might be the underlying issue here.
For testing purposes I've tried registering a new user using Pidgin and it went through without problems, though it did require confirming reception of server's self-signed certificate.

What I Did

My almost-minimal not working example:

#!/usr/bin/env python3

from spade.agent import Agent

class TestAgent(Agent):
	def setup(self):
		print("test agent setup")

def main():
	print("Creating agent...")
	serverAgent = TestAgent("[email protected]", "pass1234")
	print("Agent created, starting...")
	serverAgent.start()
	print("Agent started, stopping...")
	serverAgent.stop()
	print("Agent stopped, closing!")

if __name__ == "__main__":
	main()

run as $ pipenv run ./testRegister.py outputs:

Hello,
I am suddenly facing this issue where I can run code using SPADE just once. When I run the same code for the second time, I get the error "Could not open port xxxx". When I restart my computer, and rerun the same code, it works perfect, only once though. Is there something I am doing wrong? I am running the runTest.py code from the auction folder in the examples.
I have tried re running the code in an Anaconda environment as well as the normal python environment. Please find attached a screenshot of the error I am getting.

Would be really helpful if you could help fix this issue.

Thank you

Hi,

I would like to know if SPADE is interoperable with other FIPA agent platforms, for instance JADE ?

If someone already did it, it would be great to have an example... And if someone think its not possible, it would be great to know before investing time in it. Otherwise, I'm planning to give it a try.

I created "myFirstAgent.py":

import spade

class MyAgent(spade.Agent.Agent):
        def _setup(self):
                print ("MyAgent starting . . .")
                
if __name__ == "__main__":
	a = MyAgent("[email protected]", "secret")
	a.start()

but when i execute the above code, i got the following error:

[email protected]:[spade] There is no SPADE platform at myhost.myprovider.com . Agent dying... , error
[email protected]:[spade] Could not register agent [email protected] , error
[email protected]:[spade] Did not send 'unavailable' presence: 'MyAgent' object has no attribute 'roster' , warn
AgentNotRegisteredError

How can i register my agent ? how can i resolve this error ?

Thank you for your help

I have this error:

But my code it's simple:

!/usr/bin/env python

import threading,spade,os,sys,subprocess

class AgentNode(spade.Agent.Agent):
def _setup(self):
sys.stdout.write("Agent Node Starting...\n")

def main():
machine=subprocess.check_output("uname -n | tr -d '.'",shell=True).strip().upper()
agent=AgentNode("node"+machine+"@127.0.0.1","node"+machine+"secret")
agent.start()

if name == "main":
main()

And the server log:

It seems that they could not auth. Whats going on? Thank!

I just wrote my first agent program from the example that you give in the instructions, but when I run it, it just appears "Starting agent. . . " and it doesn't show the rest "Agent: [email protected] registered correctly (inform)".
I suposse it's something about the start method.
I'm using myhost as 127.0.0.1.
Could you please help me?
Thanks!

www.cellbots.org is using XMPP for "chat" between cell phone on robot and host server.

This gave me the idea of running a SPADE agent on python scripting environment on android phone.

Is SPADE2 able to be parred back to run client on a python powered phone?

• SPADE version:3.0
• Python version:3.6
• Operating System:Linux

Description

I have written a pyton class to demonstrate the agent. Can I send ejabbered ID and the password as parameters to this class and clone the behavior? I mean can I create more than one agent using the same python class?

Hi,

I followed the instructions on the page "My first SPADE agent" (http://spade.gti-ia.dsic.upv.es/manuals/html-chunk/spade.basicagents.first.html). But when I run my script file, it gives me this error on the console:

I configured the package with different hostnames like "localhost" or "myhost.myprovider.com". But I always get this error.

What am I missing? Please help.

I'm getting following error on both Ubuntu 12.04 and Mac.
