Aim integrations

Integrate with Aim using LangChain Python.

Aim makes it super easy to visualize and debug LangChain executions. Aim tracks inputs and outputs of LLMs and tools, as well as actions of agents.

With Aim, you can easily debug and examine an individual execution:

Additionally, you have the option to compare multiple executions side by side:

Aim is fully open source, learn more about Aim on GitHub.

Let’s move forward and see how to enable and configure Aim callback.

Tracking LangChain Executions with Aim

In this notebook we will explore three usage scenarios. To start off, we will install the necessary packages and import certain modules. Subsequently, we will configure two environment variables that can be established either within the Python script or through the terminal.

pip install -qU  aim
pip install -qU  langchain
pip install -qU  langchain-openai
pip install -qU  google-search-results

import os
from datetime import datetime

from langchain_community.callbacks import AimCallbackHandler
from langchain_core.callbacks import StdOutCallbackHandler
from langchain_openai import OpenAI

Our examples use a GPT model as the LLM, and OpenAI offers an API for this purpose. You can obtain the key from the following link: platform.openai.com/account/api-keys .

We will use the SerpApi to retrieve search results from Google. To acquire the SerpApi key, please go to serpapi.com/manage-api-key .

os.environ["OPENAI_API_KEY"] = "..."
os.environ["SERPAPI_API_KEY"] = "..."

The event methods of AimCallbackHandler accept the LangChain module or agent as input and log at least the prompts and generated results, as well as the serialized version of the LangChain module, to the designated Aim run.

session_group = datetime.now().strftime("%m.%d.%Y_%H.%M.%S")
aim_callback = AimCallbackHandler(
    repo=".",
    experiment_name="scenario 1: OpenAI LLM",
)

callbacks = [StdOutCallbackHandler(), aim_callback]
llm = OpenAI(temperature=0, callbacks=callbacks)

The flush_tracker function is used to record LangChain assets on Aim. By default, the session is reset rather than being terminated outright.

# scenario 1 - LLM
llm_result = llm.generate(["Tell me a joke", "Tell me a poem"] * 3)
aim_callback.flush_tracker(
    langchain_asset=llm,
    experiment_name="scenario 2: Chain with multiple SubChains on multiple generations",
)

from langchain_classic.chains import LLMChain
from langchain_core.prompts import PromptTemplate

# scenario 2 - Chain
template = """You are a playwright. Given the title of play, it is your job to write a synopsis for that title.
Title: {title}
Playwright: This is a synopsis for the above play:"""
prompt_template = PromptTemplate(input_variables=["title"], template=template)
synopsis_chain = LLMChain(llm=llm, prompt=prompt_template, callbacks=callbacks)

test_prompts = [
    {
        "title": "documentary about good video games that push the boundary of game design"
    },
    {"title": "the phenomenon behind the remarkable speed of cheetahs"},
    {"title": "the best in class mlops tooling"},
]
synopsis_chain.apply(test_prompts)
aim_callback.flush_tracker(
    langchain_asset=synopsis_chain, experiment_name="scenario 3: Agent with Tools"
)

from langchain.agents import create_agent, load_tools

# scenario 3 - Agent with Tools
tools = load_tools(["serpapi", "llm-math"], llm=llm, callbacks=callbacks)

agent = create_agent(
    model=llm,
    tools=tools,
    callbacks=callbacks,
)

agent.invoke(
    "Who is Leo DiCaprio's girlfriend? What is her current age raised to the 0.43 power?"
)

aim_callback.flush_tracker(langchain_asset=agent, reset=False, finish=True)

> Entering new AgentExecutor chain...
 I need to find out who Leo DiCaprio's girlfriend is and then calculate her age raised to the 0.43 power.
Action: Search
Action Input: "Leo DiCaprio girlfriend"
Observation: Leonardo DiCaprio seemed to prove a long-held theory about his love life right after splitting from girlfriend Camila Morrone just months ...
Thought: I need to find out Camila Morrone's age
Action: Search
Action Input: "Camila Morrone age"
Observation: 25 years
Thought: I need to calculate 25 raised to the 0.43 power
Action: Calculator
Action Input: 25^0.43
Observation: Answer: 3.991298452658078

Thought: I now know the final answer
Final Answer: Camila Morrone is Leo DiCaprio's girlfriend and her current age raised to the 0.43 power is 3.991298452658078.

> Finished chain.
