TensorFlow – End-to-End Machine Learning Platform

TensorFlow is an open-source machine learning platform developed by Google that provides a comprehensive ecosystem for building, training, and deploying ML models. From research prototypes to production systems, TensorFlow offers flexibility and scalability across various platforms including servers, edge devices, browsers, and mobile phones. It remains one of the most widely adopted frameworks in enterprise AI deployments.

Key Features

• Keras Integration – High-level API for rapid model development
• Production Ready – TensorFlow Serving for model deployment
• Multi-Platform – Deploy on servers, mobile, edge, and browsers
• TensorBoard – Powerful visualization and debugging tools
• Distributed Training – Scale across multiple GPUs and TPUs
• SavedModel Format – Portable model serialization
• TF Hub – Repository of pre-trained models

Installation on Linux

# Install TensorFlow with pip
pip install tensorflow

# Install with GPU support (requires NVIDIA drivers and CUDA)
pip install tensorflow[and-cuda]

# Verify installation
python -c "import tensorflow as tf; print(tf.__version__)"
python -c "import tensorflow as tf; print(tf.config.list_physical_devices('GPU'))"

Basic Usage Example

import tensorflow as tf
from tensorflow import keras

# Build a simple model with Keras
model = keras.Sequential([
    keras.layers.Dense(128, activation='relu', input_shape=(784,)),
    keras.layers.Dropout(0.2),
    keras.layers.Dense(10, activation='softmax')
])

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

# Train the model
model.fit(x_train, y_train, epochs=5, validation_split=0.2)

# Evaluate and save
model.evaluate(x_test, y_test)
model.save('my_model.keras')
