%description
Theano is a Python library that allows you to define, optimize, and
evaluate mathematical expressions involving multi-dimensional arrays
efficiently.  Theano features:
- tight integration with NumPy: Use numpy.ndarray in Theano-compiled
  functions.
- transparent use of a GPU: Perform data-intensive calculations up to
  140x faster than with CPU.(float32 only)
- efficient symbolic differentiation: Theano does your derivatives for
  function with one or many inputs.
- speed and stability optimizations: Get the right answer for log(1+x)
  even when x is really tiny.
- dynamic C code generation: Evaluate expressions faster.
- extensive unit-testing and self-verification: Detect and diagnose many
  types of mistake.
