An easy way to implement Tensor and Autograd

Tensor is a data type or class that represents an array, or rather an ndimensional array because it is not limited to certain dimensions. Autograd is a package which makes it easier to perform derivative calculations (differential).

  • function 1 : torch.cat
  • function 2 : torch.argmax
  • function 3 : torch.argsort
  • function 4 : Function 4 - requeres_grad
  • function 5 : Function 5 - torch.FloatTensor

Before we begin, let's install and import PyTorch

Function 1 - torch.cat

The torch.cat function aims to combine the sequences contained in the dimensions.
