1. TensorFlow & TensorFlow Extended (TFX)

TensorFlow remains the gold standard for machine learning development, and TensorFlow Extended (TFX) takes it to production scale. With its comprehensive ecosystem, TensorFlow provides everything from model development to deployment.

import tensorflow as tf
from tensorflow import keras

# Example: Building a simple neural network
model = keras.Sequential([
    keras.layers.Dense(128, activation='relu', input_shape=(784,)),
    keras.layers.Dropout(0.2),
    keras.layers.Dense(10, activation='softmax')
])

model.compile(optimizer='adam',
              loss='sparse_categorical_crossentropy',
              metrics=['accuracy'])

# Training with built-in callbacks
callbacks = [
    keras.callbacks.EarlyStopping(patience=3),
    keras.callbacks.ModelCheckpoint('best_model.h5', save_best_only=True)
]

model.fit(x_train, y_train, 
          validation_data=(x_val, y_val),
          epochs=50, 
          callbacks=callbacks)

2. PyTorch & PyTorch Lightning

PyTorch has gained massive popularity for its dynamic computation graphs and intuitive API. Combined with PyTorch Lightning, it provides a structured approach to organizing PyTorch code for better reproducibility and scalability.

PyTorch Lightning eliminates boilerplate code and provides best practices out of the box, making it easier to scale from research to production.

import pytorch_lightning as pl
import torch
import torch.nn as nn
import torch.nn.functional as F

class LitModel(pl.LightningModule):
    def __init__(self, input_size, hidden_size, num_classes):
        super().__init__()
        self.layer_1 = nn.Linear(input_size, hidden_size)
        self.layer_2 = nn.Linear(hidden_size, num_classes)
        
    def forward(self, x):
        x = F.relu(self.layer_1(x))
        x = self.layer_2(x)
        return x
    
    def training_step(self, batch, batch_idx):
        x, y = batch
        y_hat = self(x)
        loss = F.cross_entropy(y_hat, y)
        self.log('train_loss', loss)
        return loss
    
    def configure_optimizers(self):
        return torch.optim.Adam(self.parameters(), lr=0.001)

# Training is simplified
trainer = pl.Trainer(max_epochs=10, gpus=1)
model = LitModel(784, 128, 10)
trainer.fit(model, train_dataloader)

3. Hugging Face Transformers

The Hugging Face ecosystem has revolutionized natural language processing and computer vision. With thousands of pre-trained models and a simple API, it's become the go-to platform for transformer-based models.

from transformers import pipeline, AutoTokenizer, AutoModel

# Quick sentiment analysis
classifier = pipeline("sentiment-analysis")
result = classifier("I love using Hugging Face!")
print(result)  # [{'label': 'POSITIVE', 'score': 0.9998}]

# Custom model loading
tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
model = AutoModel.from_pretrained("bert-base-uncased")

# Text generation with GPT
generator = pipeline("text-generation", model="gpt2")
output = generator("The future of AI development is", 
                  max_length=50, 
                  num_return_sequences=2)

4. MLflow

MLflow is essential for managing the machine learning lifecycle. It provides experiment tracking, model versioning, and deployment capabilities that are crucial for production AI systems.

With MLflow, you can track experiments, package models, and deploy them across different platforms with consistent APIs.

5. Weights & Biases (wandb)

Weights & Biases offers superior experiment tracking and visualization capabilities. It's particularly powerful for deep learning projects where you need to monitor training metrics, hyperparameters, and model performance.

6. Docker & Kubernetes

While not AI-specific, Docker and Kubernetes are essential for deploying AI models at scale. They provide containerization and orchestration capabilities that ensure your models run consistently across different environments.

Docker containers solve the "it works on my machine" problem, while Kubernetes handles scaling, load balancing, and service discovery for production deployments.

7. Apache Airflow

Apache Airflow is crucial for orchestrating complex AI workflows. From data preprocessing to model training and deployment, Airflow helps you build reliable, scalable data pipelines.

    pass

default_args = {
    'owner': 'ai-team',
    'depends_on_past': False,
    'start_date': datetime(2025, 1, 1),
    'retries': 1,
    'retry_delay': timedelta(minutes=5)
}

dag = DAG(
    'ai_model_pipeline',
    default_args=default_args,
    description='AI model training and deployment pipeline',
    schedule_interval=timedelta(days=1),
    catchup=False

    st.write("Data Preview:")
    st.dataframe(data.head())
    
    # Model parameters
    n_estimators = st.slider('Number of trees', 10, 100, 50)
    max_depth = st.slider('Max depth', 1, 20, 10)
    
    if st.button('Train Model'):
        # Training logic here
        model = RandomForestClassifier(
            n_estimators=n_estimators,
            max_depth=max_depth
        )
        # model.fit(X, y)
