In this subsection, we will demonstrate the usage of a GPU with Theano and Tensorflow. As an example, we will benchmark the execution of a very simple matrix multiplication on the GPU and compare it to its running time on a CPU.
The code in this subsection requires the possession of a GPU. For learning purposes, it is possible to use the Amazon EC2 service (https://aws.amazon.com/ec2) to request a GPU-enabled instance.
The following code performs a simple matrix multiplication using Theano. We use the T.matrix function to initialize a two-dimensional array, and then we use the T.dot method to perform the matrix multiplication:
from theano import function, config import theano.tensor as T import numpy as np import time ...
