Abstract Deep learning frameworks have often focused on either usability or speed, but not both. Py. Torch is a machine learning library that shows that these two goals are in fact compatible: it was designed from first principles to support an imperative and Pythonic programming style that supports code as a model, makes debugging easy and is consistent with other popular scientific computing libraries, while remaining efficient and supporting hardware accelerators such as GPUs.

Introduction Usually Py. Torch is used either as: ● a replacement for Num. Py to use the power of GPUs. ● a deep learning research platform that provides maximum flexibility and speed.

Why Py. Torch? ● ● ● Regular Python program User has full control Compelling performance Most of code developed on C++ Researcher’s favorite Can use your favorite libraries and packages

Tensors

Tensors Py. Torch provides Tensors that can live either on the CPU or the GPU, and accelerates the computation by a huge amount.

Tensor vs matrix

Work of Tensor ● ● ● Slicing Indexing Math operations Linear algebra Reductions
