Comparison
TensorFlow offers production-ready tools and a mature ecosystem, while PyTorch provides dynamic computation graphs and intuitive research-oriented design. Both are excellent choices with different strengths.

Installation and Setup
Learn proper installation procedures, environment setup, and configuration for both frameworks.
Installation Options:
• CPU-only versions for development and testing
• GPU-enabled versions for training acceleration
• Conda vs pip installation methods
• Docker containers for consistent environments
• Cloud platform integrations
GPU Setup Considerations:
Ensure CUDA and cuDNN versions are compatible with your framework version. Use conda for easier dependency management, especially with GPU libraries.

Computational Graphs
Understand how computational graphs work in both static and dynamic paradigms.
Graph Types:
• Static graphs: Define then run (TensorFlow 1.x, TorchScript)
• Dynamic graphs: Define by run (PyTorch, TensorFlow 2.x eager)
• Hybrid approaches: Best of both worlds
Trade-offs:
Static graphs enable optimizations and deployment efficiency, while dynamic graphs provide flexibility and easier debugging. Modern frameworks offer both options.
