ValueError: Agents must be provided. [BUG]

[Veanir]

Describe the bug
BaseSwarm class throws value error when instantiating SwarmNetwork when using provided Swarm Network example.

To Reproduce
Steps to reproduce the behavior:

1. Go to Swarms documentation
2. Install swarms like intended
3. Run provided "Swarm Network" code eg.

import os

from dotenv import load_dotenv

# Import the OpenAIChat model and the Agent struct
from swarms import Agent, OpenAIChat, SwarmNetwork

# Load the environment variables
load_dotenv()

# Get the API key from the environment
api_key = os.environ.get("OPENAI_API_KEY")

# Initialize the language model
llm = OpenAIChat(
    temperature=0.5,
    openai_api_key=api_key,
)

## Initialize the workflow
agent = Agent(llm=llm, max_loops=1, agent_name="Social Media Manager")
agent2 = Agent(llm=llm, max_loops=1, agent_name=" Product Manager")
agent3 = Agent(llm=llm, max_loops=1, agent_name="SEO Manager")


# Load the swarmnet with the agents
swarmnet = SwarmNetwork(
    agents=[agent, agent2, agent3],
)

# List the agents in the swarm network
out = swarmnet.list_agents()
print(out)

# Run the workflow on a task
out = swarmnet.run_single_agent(
    agent2.id, "Generate a 10,000 word blog on health and wellness."
)
print(out)


# Run all the agents in the swarm network on a task
out = swarmnet.run_many_agents("Generate a 10,000 word blog on health and wellness.")
print(out)

4. Watch error in the console.

Screenshots

Additional context
Python 3.12.2
swarms installed via pip

@Veanir hey excuse, me think i just fixed it, try upgrading and then let me know: pip3 install -U swarms

I set up a colab notebook replicator with the latest swarms.
It ran, but ran out of memory after only producing

32m2024-06-17T23:14:10.620655+0000�[0m �[1mReliability checks activated.�[0m

If interrupted before running out of memory I get;

KeyboardInterrupt                         Traceback (most recent call last)

I'll dig in a bit more.

Yea, seems like infinite loop to me

# For each agent in the pool, run it on it's own thread
        if agents is not None:
            for agent in agents:
                self.agents.append(agent)

[evelynmitchell]

Ok, I think I figured this out. This code is recursively adding agents to agents, and so will never stop, and will oom.
swarms/structs/swarm_net.py 144
You likely don't need this code at all. The agents have already been added with self.agents.

       # For each agent in the pool, run it on it's own thread
        if agents is not None:
            for agent in agents:
                self.agents.append(agent)

@Veanir @evelynmitchell i've tried fixing it, thanks good catch. try upgrading now!
