5 Mathematical Pytorch Functions
PyTorch functions are very easy to use. There are some functions through whhich we can do mathematical functions very efficiently.
- torch.eye
- torch.randn
- torch.where
- torch.range
- torch.movedim
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.eye
We use this function when we have to create an identity matrix of n dimension
# Example 1 -
torch.eye(3,3)
tensor([[1., 0., 0.],
[0., 1., 0.],
[0., 0., 1.]])
