Lyzr-Automata is a low-code multi-agent automation framework that enables us to break down complex tasks into simple agents and thread them together. In this blog post, we’ll create an Automated Newsletter Publisher using lyzr-automata.
Setup
Create a folder, set up a virtual environment and activate it
virtualenv my_env
source my_env/bin/activate
Install the following packages
lyzr-automata==0.1.2
python-dotenv==1.0.1
Setup .env file
OPENAI_API_KEY = "YOUR OPENAI API KEY"
EMAIL = "YOUR EMAIL ID"
PASSWORD = "YOUR APP PASSWORD"
Note: To get your App Password, follow these steps here
Get Started
Let’s create a file main.py and use that
1.Load .env variables
from dotenv import load_dotenv
import os
load_dotenv()
OPENAI_API_KEY = os.getenv("OPENAI_API_KEY")
PASSWORD = os.getenv("PASSWORD")
EMAIL = os.getenv("EMAIL")
2.Initialise our Model
A Text to Text model to create content (GPT-4)
A Text to Image model to create a suitable image (DALLE-3)
open_ai_model_text = OpenAIModel(
api_key=OPENAI_API_KEY,
parameters={
"model": "gpt-4-turbo-preview", # Specify Model
"temperature": 0.2, # Creativity of the model
"max_tokens": 1500, # Maximum tokens
},
)
open_ai_model_image = OpenAIModel(
api_key=OPENAI_API_KEY,
parameters={
"n": 1, # Number of images
"model": "dall-e-3", # Specify Model
},
)
3.Build our agent
from lyzr_automata import Agent
content_researcher_agent = Agent(
prompt_persona="You are an intelligent Travel Newsletter writer good at writing a detailed newsletter on a particular destination",
role="Travel Newsletter writer",
)
4. Implement our Tasks
from lyzr_automata import Task
from lyzr_automata.tasks.task_literals import InputType, OutputType
# Newsletter Content Creator Task
research_task = Task(
name="Draft Content Creator",
agent=content_researcher_agent,
output_type=OutputType.TEXT,
input_type=InputType.TEXT,
model=open_ai_model_text,
instructions="Write a travel newsletter on Mumbai in 500 words and [IMPORTANT!] send the response in html use bullets for points and beautify it be as creative as you want.",
log_output=True,
enhance_prompt=False,
)
# Image Creator Task
image_creation_task = Task(
name="Newsletter Image Creation",
output_type=OutputType.IMAGE,
input_type=InputType.TEXT,
model=open_ai_model_image,
log_output=True,
instructions="Use the travel newsletter provided and create an image that would be suitable for posting. Avoid any text in the image",
)
# Merge Image and Content Task
merge_image_text_task = Task(
name = "Merge Image and Email",
model=open_ai_model_text,
log_output=True,
instructions="Include the image in the html code provided. Return only the HTML and CSS code",
input_tasks = [research_task, image_creation_task]
)
5.Create our Email Sender Tool
from lyzr_automata.tools.prebuilt_tools import send_email_by_smtp_tool
email_sender = send_email_by_smtp_tool(
username=EMAIL,
password=PASSWORD,
host="smtp.gmail.com",
port=587,
sender_email=EMAIL
)
send_email_task = Task(
name = "Send Email Task",
tool = email_sender,
instructions="Send Email",
model=open_ai_model_text,
input_tasks = [merge_image_text_task],
default_input = ["EMAIL1", "EMAIL2"] # Specify Reciever Email IDs HERE
)
6.Create Pipeline and execute the tasks
from lyzr_automata.pipelines.linear_sync_pipeline import LinearSyncPipeline
from lyzr_automata import Logger
def main_program():
logger = Logger()
LinearSyncPipeline(
logger=logger,
name="Send Email",
completion_message="Email Sent!",
tasks=[
research_task,
image_creation_task,
merge_image_text_task,
send_email_task
],
).run()
main_program()
7.Run the file and find the email in your inbox!
