Five interesting PyTorch functions!

This is a short introductory assignment showing five interesting Pytorch functions

  • torch.zeros
  • torch.reshape
  • torch.vstack
  • torch.ones
  • torch.split

Before we begin, let's install and import PyTorch

# Uncomment and run the appropriate command for your operating system, if required

# Linux / Binder
# !pip install numpy torch==1.7.0+cpu torchvision==0.8.1+cpu torchaudio==0.7.0 -f https://download.pytorch.org/whl/torch_stable.html

# Windows
!pip install numpy torch==1.7.0+cpu torchvision==0.8.1+cpu torchaudio==0.7.0 -f https://download.pytorch.org/whl/torch_stable.html

# MacOS
# !pip install numpy torch torchvision torchaudio

# Import torch and other required modules
import torch

Function 1 - torch.zeros

Returns a tensor filled with the scalar value 0, with the shape defined by the variable argument size

torch.zeros(2, 3)
tensor([[0., 0., 0.],
        [0., 0., 0.]])
