Interesting Functions in tensor

An short introduction about PyTorch and about the chosen functions.

Divide Function
Cosine Function
Chunk Function
HStack Function
Reshape Function

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

Dividing each elements in x by elements in y

x = torch.tensor([[1., 3, 5], 
                 [2, 4, 6]])
y = torch.full((2, 3), 4.)
torch.div(x, y)

tensor([[0.2500, 0.7500, 1.2500],
        [0.5000, 1.0000, 1.5000]])
