Theano is an open-source numerical computation library for Python, designed for optimizing and evaluating mathematical expressions, particularly in deep learning and machine learning applications. It provides efficient handling of multi-dimensional arrays and GPU acceleration, making it a powerful tool for scientific computing.

Features of Theano:

• Optimized for mathematical expressions, particularly tensor computations.
• Supports GPU acceleration for faster performance.
• Automatic differentiation for gradient-based optimization.
• Integration with NumPy for seamless data handling.
• Allows efficient compilation and execution of symbolic expressions.

To Access Theano create virtual enviroment, run:
$python -m venv ~/theano-venv

run:
$source ~/theano-venv/bin/activate

To check the installed version of Theano, run:
$ python -c "import theano; print(theano.__version__)"
