Assignment Instructions (delete this cell before submission)

The objective of this assignment is to develop a solid understanding of PyTorch tensors. In this assignment you will:

  1. Pick 5 interesting functions related to PyTorch tensors by reading the documentation,

  2. Edit this starter template notebook to illustrate their usage and publish your notebook to Jovian using jovian.commit. Make sure to add proper explanations too, not just code.

  3. Submit the link to your published notebook on Jovian here: https://jovian.ai/learn/deep-learning-with-pytorch-zero-to-gans/assignment/assignment-1-all-about-torch-tensor .

  4. (Optional) Write a blog post on Medium to accompany and showcase your Jupyter notebook. Embed cells from your notebook wherever necessary.

  5. (Optional) Share your work with the community and exchange feedback with other participants

The recommended way to run this notebook is to click the "Run" button at the top of this page, and select "Run on Colab". Run jovian.commit regularly to save your progress.

Try to give your notebook an interesting title e.g. "All about PyTorch tensor operations", "5 PyTorch functions you didn't know you needed", "A beginner's guide to Autograd in PyToch", "Interesting ways to create PyTorch tensors", "Trigonometic functions in PyTorch", "How to use PyTorch tensors for Linear Algebra" etc.

IMPORTANT NOTE: Make sure to submit a Jovian notebook link e.g. https://jovian.ai/aakashns/01-tensor-operations . Colab links will not be accepted.

Remove this cell containing instructions before making a submission or sharing your notebook, to make it more presentable.

5 Ways to Create Tensors using Pytorch

Pytorch is essentially an open source machine learning framework developed by Facebook's AI research group. Pytorch uses dynamic computation unlike other deep learning frameworks (e.g. TensorFlow), making it flexible and easier to develop complex models. The use of classes, structures and loops make it easier to understand and use, compared to frameworks that use a different programming style.

This notebook has compiled 5 tensor functions that can be used to create tensors. The first two functions are based on simple ideas of creating and arranging a tensor, whereas the following three functions generate mathematical equivalent forms of tensors- complex, heavyside step and polar.

  • function 1: empty
  • function 2: arrange
  • function 3: complex
  • function 4: heavyside step
  • function 5: polar

Prerequisite: 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 - Empty function

Returns a tensor filled with uninitialized data. The shape of the tensor is defined by the variable argument 'size'. 'Size' takes in the rows and columns of the expected tensor.
