2. PyTorch

PyTorch’s popularity continues to surge for research and production. Its dynamic computation graph enables flexibility and ease for prototyping.

Strengths: Intuitive, Pythonic interface, excellent debugging support, and a rich set of pre-trained models via Torch Hub.
Use Cases: Research projects, NLP transformers, GANs, and health AI models.

3. scikit-learn

scikit-learn (Official site) is the go-to for classical ML algorithms like classification, regression, and clustering. It’s lightweight and easy to use, making it perfect for beginners and traditional ML workflows.

Strengths: Huge algorithm library, consistent API, strong documentation.
Use Cases: Predictive analytics, small to medium datasets, feature engineering.

4. JAX

JAX has gained traction for machine learning research that requires high-performance numerical computing. It automates differentiation and supports GPU/TPU acceleration.

Strengths: Functional programming style, just-in-time compilation with XLA, and composability.
Use Cases: Scientific machine learning, custom optimization algorithms, and experimental research.

5. Apache MXNet

Apache MXNet (Official site) offers efficient scalable training and supports multiple languages including Python, Scala, and R.

Strengths: Model serving support, distributed computing, and good for deep learning on edge devices.
Use Cases: Real-time inference, IoT AI workloads, large-scale datasets.

Step-by-Step Getting Started (Example: TensorFlow)

Install TensorFlow:
```
pip install tensorflow
```

Verify installation:

python -c "import tensorflow as tf; print(tf.__version__)"

Basic example – Train a simple model:

import tensorflow as tf
from tensorflow.keras import layers, models

# Load dataset
mnist = tf.keras.datasets.mnist
(x_train, y_train), (x_test, y_test) = mnist.load_data()
x_train, x_test = x_train / 255.0, x_test / 255.0

# Build model
model = models.Sequential([
  layers.Flatten(input_shape=(28, 28)),
  layers.Dense(128, activation='relu'),
  layers.Dropout(0.2),
  layers.Dense(10, activation='softmax')
])

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

# Train
model.fit(x_train, y_train, epochs=5)

# Evaluate
model.evaluate(x_test, y_test)

Troubleshooting Tips

Installation issues: Ensure your Python version is compatible and update pip before installing.
GPU acceleration not detected: Confirm CUDA and cuDNN versions match TensorFlow/PyTorch requirements.
Slow training: Use batch sizes that fit your GPU memory and consider switching to mixed precision training.
API changes: Refer to the official documentation for the latest updates in each framework.
