Keras is an open-source deep learning API written in Python, designed for fast experimentation with neural networks. It provides a user-friendly, high-level interface to build and train deep learning models, and runs on top of TensorFlow, JAX, or PyTorch. Keras is widely adopted in both research and industry due to its simplicity and extensibility.

Features of Keras:

• High-level API for building deep learning models easily.
• Supports multiple backends: TensorFlow, JAX, and PyTorch (via Keras Core).
• Modular and extensible architecture for custom model development.
• Includes pre-built layers, optimizers, loss functions, and metrics.
• Compatible with CPUs and GPUs for scalable performance.

To activate the Keras environment and check its version, run:

cd /opt
source keras-env/bin/activate
pip show keras
