theano Documentation Release 1.0.0 LISA lab, University of Montreal November 21, 2017 CONTENTS News Download Citing Theano Documentation Community 11 Help! 13 Python Module Index 637 i ii theano Documentation, Release 1.0.0 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 computations much faster than on a CPU • efficient symbolic differentiation – Theano does your derivatives for functions 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 errors Theano has been powering large-scale computationally intensive scientific investigations since 2007 But it is also approachable enough to be used in the classroom (University of Montreal’s deep learning/machine learning classes) CONTENTS theano Documentation,

2010, June 30, 2010 Chapter News CHAPTER TWO DOWNLOAD Theano is now available on PyPI, and can be installed via easy_install Theano, pip install Theano or by downloading and unpacking the tarball and typing python setup.py install Those interested in bleeding-edge features should obtain the latest development version, available via: git clone git://github.com/Theano/Theano.git You can then place the checkout directory on your $PYTHONPATH or use python setup.py develop to install a pth into your site-packages directory, so that when you pull updates via Git, they will be automatically reflected the “installed” version For more information about installation and configuration, see installing Theano theano Documentation, Release 1.0.0 Chapter Download theano Documentation, Release
