What is Pytorch? Pytorch is a Python - based framework in machine learning primarily used for scientific computations and to build deep learning models. A Tensor is a popular concept in Machine learning and Data science. Tensors are a generalized term for matrices and vectors. In simple words, Tensors can be anything - a n-dimensional array, a vector, or a matrix. In this article, we will be looking at the multiple methods used to create Tensors in Pytorch. Method of Creating Tensors Tensors can be created in multiple methods. Some of the important methods are listed below. ... Read More

To find the indices of the maximum value of the elements in an input tensor, we can apply the torch.argmax() function. It returns the indices only, not the element value. If the input tensor has multiple maximal values, then the function will return the index of the first maximal element. We can apply the torch.argmax() function to compute the indices of the maximum values of a tensor across a dimension..Syntaxtorch.argmax(input)StepsWe could use the following steps to find the indices of the maximum values of all elements in the input tensor −Import the required library. In all the following examples, the ... Read More

To compute elementwise logical AND of given input tensors we apply torch.logical_and(). It takes two input tensors and computes the logical AND element wise. The zeros in the tensors are treated as False and non-zeros as True. The input tensors may be of any dimension.The torch.logical_or() function computes elementwise logical OR of the given input tensors. It also takes two input tensors and outputs a tensor with True or False. As same in logical AND zeros are treated as False and non-zeros are treated as True.The input tensors may be of any dimension.To compute the elementwise NOT of a given ... Read More

To estimate the gradient of a function, we can apply the torch.gradient() function. This function estimates the gradient using the second-order accurate central differences method. We can estimate the gradient in one or more dimensions. The function of which the gradient is to be estimated may be defined on a real or complex domain. In the process of estimating the gradients, the gradient is estimated by estimating each partial derivative of the function independently.Syntaxtorch.gradient(values)where the parameter values is the tensor that represents the values of the function.StepsWe could use the following steps to estimate the gradient of a function −Import ...
