# 5 Python Libraries Every AI Engineer Should Know in 2024
The AI ecosystem is evolving rapidly, with new libraries and tools emerging constantly. Here are five Python libraries that have become indispensable for AI engineers in 2024.
## 1. LangChain - Building AI Applications
LangChain has revolutionized how we build applications with large language models:
```python
from langchain.llms import OpenAI
from langchain.chains import LLMChain
from langchain.prompts import PromptTemplate
llm = OpenAI(temperature=0.7)
prompt = PromptTemplate(
input_variables=["topic"],
template="Write a blog post about {topic}"
)
chain = LLMChain(llm=llm, prompt=prompt)
result = chain.run("machine learning")
```
**Why it matters**: Simplifies building complex AI workflows and chains.
## 2. Streamlit - Rapid AI Prototyping
Create interactive AI applications in minutes:
```python
import streamlit as st
import pandas as pd
st.title("AI Data Explorer")
uploaded_file = st.file_uploader("Choose a CSV file")
if uploaded_file:
df = pd.read_csv(uploaded_file)
st.dataframe(df)
if st.button("Generate Insights"):
insights = analyze_data(df)
st.write(insights)
```
## 3. Hugging Face Transformers - Pre-trained Models
Access thousands of pre-trained models:
```python
from transformers import pipeline
classifier = pipeline("sentiment-analysis")
result = classifier("I love this new AI library!")
# [{'label': 'POSITIVE', 'score': 0.9998}]
```
## 4. Weights & Biases - Experiment Tracking
Track and visualize your AI experiments:
```python
import wandb
wandb.init(project="my-ai-project")
wandb.log({"accuracy": 0.95, "loss": 0.05})
```
## 5. FastAPI - AI Model Deployment
Deploy AI models with automatic API documentation:
```python
from fastapi import FastAPI
from pydantic import BaseModel
app = FastAPI()
class PredictionRequest(BaseModel):
text: str
@app.post("/predict")
async def predict(request: PredictionRequest):
result = model.predict(request.text)
return {"prediction": result}
```
## Conclusion
These libraries form the foundation of modern AI development. Start incorporating them into your workflow to build better AI applications faster.
