#SOME COOL TENSOR FUNCTIONS

  • Time to check some really basic and cool functions from pytorch documentation

An short introduction about PyTorch and about the chosen functions.

  • torch.zeros
  • torch.rand
  • torch.cat
  • torch.numel
  • torch.tensor

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

The following example shows how we can make a zero vector of desired size

# Example 1 - Here we have created a vector of size 2 containing all zeros
torch.zeros(2)
tensor([0., 0.])
