🐍 PyTorch for Beginners: All the Basics on Tensors in One Place

A collection of basic techniques for working with tensors in PyTorch — for those who are starting to get acquainted with the framework and want to quickly master its fundamentals.

What's inside:

▶️ What tensors are and why they are needed

▶️ Tensor initialization: zeros, ones, random, similar size

▶️ Type conversion and switching between NumPy and PyTorch

▶️ Arithmetic, logical operations, tensor comparison

▶️ Matrix multiplication and batch computations

▶️ Broadcasting, view(), reshape(), changing dimensions

▶️ Indexing and slicing: how to access parts of a tensor

▶️ Notebook with code examples

A good starting material to understand the mechanics of tensors before moving on to models and training.

📱Cheat sheet on string methods in Python

1. Makes the first letter capitalized

.capitalize()

2. Lowers or raises the case of a string
.lower()
.upper()

3. Centers the string with symbols around it: 'Python' → 'Python'

.center(10, '*') 

4. Counts the occurrences of a specific character

.count('0')

5. Finds the positions of specified characters

.find()
.index()

6. Searches for a desired object and replaces it

.replace()

7. Splits the string, removing the split point from it
.split()

8. Checks what the string consists of
.isalnum()
.isnumeric()
.islower()
.isupper()
