AdalFlow Workflows

AdalFlow offers a comprehensive framework for managing workflows in machine learning applications. Its main strength is simplifying the creation, optimization, and execution of complex task pipelines.

Key Components of AdalFlow Workflows

Here are the key components of AdalFlow workflows:

• AdalComponent: This is the core element where task pipelines are assembled. It supports the integration of optimizers, evaluators, and loss functions. Drawing inspiration from PyTorch Lightning’s LightningModule, the AdalComponent makes it easier to transition into the Trainer, which handles training and validation stages.
• Task Pipeline: A task pipeline in AdalFlow optimizes the flow of data and operations through different stages, including data preprocessing, model training, evaluation, and deployment. Each of these stages can be customized to address specific needs, providing both flexibility and efficiency.

Example Workflow

To demonstrate a typical AdalFlow workflow:

• Data Preparation: Start by loading and preprocessing your dataset using AdalFlow’s utility functions.
• Model Definition: Define the model architecture inside an AdalComponent.
• Training: Use the Trainer to manage the training process and fine-tune hyperparameters.
• Evaluation: After training, assess the model’s performance using the built-in evaluation metrics.
• Deployment: Finally, deploy the trained model for inference in a production setting.

Code Example

Below is a simplified code snippet showing how to set up a basic AdalFlow workflow:

from adalflow import AdalComponent, Trainer

# Define the model

class MyModel(AdalComponent):

    def __init__(self):

        super().__init__()

        # Initialize model layers and components here

# Create an instance of the model

model = MyModel()

# Set up the trainer

trainer = Trainer(model=model)

# Begin training

trainer.train()

This setup outlines the core structure of an AdalFlow workflow, allowing for streamlined model development, training, and deployment.

Installing and Implementing AdalFlow

Now let’s see how to Install and Implement AdalFlow Step-by-Step:

Step 1: Setting Up the Environment

The first step is to create a clean environment and install all necessary dependencies.

conda create -n Adalflow python=3.11 -y

conda activate Adalflow

Explanation: We are creating a new conda environment called Adalflow with Python 3.11. This environment will help keep dependencies isolated from other projects.

Step 2: Cloning the AdalFlow Repository

Next, let’s clone the official AdalFlow repository from GitHub.

git clone https://github.com/SylphAI-Inc/AdalFlow.git

cd AdalFlow

Explanation: We clone the AdalFlow repository and navigate into the project directory. This allows us to access the codebase and files necessary for the AdalFlow system.

Step 3: Installing AdalFlow and Required Dependencies

Now, we should install AdalFlow and the required dependencies.

pip install adalflow

pip install openai==1.12.0

pip install faiss-cpu==1.8.0

pip install sqlalchemy==2.0.30

pip install pgvector==0.2.5

pip install groq==0.5.0

1. adalflow: Installs the Adalflow package.
2. Openai: Installs a specific version of the OpenAI API.
3. faiss-cpu: Adds FAISS for efficient similarity search.
4. sqlalchemy: A popular SQL toolkit for working with databases.
5. pgvector: Provides vector extensions for PostgreSQL databases.
6. groq: Integrates with the Groq API for model serving.

Step 4: Setting Up the .env File

Set your API keys for OpenAI and Groq and shore in .env .This file will store your API keys and other environment-specific settings that AdalFlow will use to authenticate requests.

Step 5: Install Jupyter Notebook

Install Jupyter Notebook to run and test your code interactively.

conda install jupyter -y

This installs Jupyter Notebook in the AdalFlow environment, allowing you to work with your project in an interactive Python environment.

Step 6: Fixing the charset_normalizer Issue

A known issue with charset_normalizer is resolved by uninstalling and reinstalling it.

pip uninstall charset_normalizer -y

pip install charset_normalizer

In this step we are addressing a dependency issue by reinstalling charset_normalizer, which might be required by one of the other libraries.

Step 7: Launch Jupyter Notebook

Once everything is set up, launch Jupyter Notebook.

Jupyter Notebook is launched. You can now open a .ipynb file or create a new notebook to experiment with the AdalFlow system.

Step 8: Setting Up the Environment Programmatically

In the notebook, set up the environment for AdalFlow.

from adalflow.utils import setup_env

setup_env()

setup_env() configures your environment using the values defined in your .env file. This function ensures that all necessary configurations and API keys are properly loaded.

Step 9: Defining a Data Class for Q&A Output

You define a data class that will hold the model’s output.

from dataclasses import dataclass, field

from adalflow.core import Component, Generator, DataClass

from adalflow.components.model_client import GroqAPIClient

from groq import Groq

from adalflow.components.output_parsers import JsonOutputParser

@dataclass

class QAOutput(DataClass):

    explanation: str = field(

        metadata={"desc": "A brief explanation of the concept in one sentence."}

    )

    example: str = field(metadata={"desc": "An example of the concept in a sentence."})

QAOutput is a data class used to structure the response from the model. It has two fields: explanation and example, which will hold the explanation and example for the user query.

Step 10: Creating the Q&A Template

Now, create a prompt template for generating the Q&A responses.

qa_template = r"""<SYS>

You are a helpful assistant.

<OUTPUT_FORMAT>

{{output_format_str}}

</OUTPUT_FORMAT>

</SYS>

User: {{input_str}}

You:"""

Explanation: This string template defines the system’s prompt, including the role of the assistant, the expected output format, and the user query. The placeholders {{output_format_str}} and {{input_str}} are dynamically replaced with the actual format instructions and query during execution.

Step 11: Defining the Q&A Component

Define a class QA that represents the Q&A logic:

class QA(Component):

    def __init__(self):

        super().__init__()

        parser = JsonOutputParser(data_class=QAOutput, return_data_class=True)

        self.generator = Generator(

            model_client=GroqAPIClient(),

            model_kwargs={"model": "llama3-8b-8192"},

            template=qa_template,

            prompt_kwargs={"output_format_str": parser.format_instructions()},

            output_processors=parser,

        )

    def call(self, query: str):

        return self.generator.call({"input_str": query})

    async def acall(self, query: str):

        return await self.generator.acall({"input_str": query})

• QA: The main component that handles querying the model.
• JsonOutputParser: Parses the model’s output into structured JSON format based on QAOutput.
• Generator: Uses GroqAPIClient to communicate with the model, with the specific model llama3-8b-8192 being called.
• call: A synchronous method that sends the user query to the model and returns the processed result.
• acall: The asynchronous version of the call method for handling queries asynchronously.

Step 12: Creating an Instance of the Q&A Component

Instantiate the QA component and test it.

qa = QA()

print(qa)

This creates an instance of the QA class, which is ready to handle user queries. Printing qa will output the component details, confirming that the setup is correct.

Output:

Step 13: Sending a Query to the Model

We can send a query to the model and retrieve the output.

output = qa("What is AdalFlow?")

print(output)

Output

output = qa("Explain the workflow of Adalflow?")

print(output)

Output

Step 14: Debugging the Prompt

Finally,  print the full prompt used to interact with the model.

qa.generator.print_prompt(

    output_format_str=qa.generator.output_processors.format_instructions(),

    input_str="What is AdalFlow?",

)

This is useful for debugging. It shows the actual prompt being sent to the model, helping in verifying that the template is being constructed correctly with the expected input and format.

Output
