##PyTORCH BASICS

Tensors & Gradients

I am going to show you a  short introduction about PyTorch and about the it's functions. 
- Torch
- Regression
- Mean Absolute Error
- Binary Classification
- Mean Squared Error 

# Import torch and other required modules
import torch

torch 

 PyTorch is a library for processing tensors.
   
A tensor is a number, vector, matrix or any n-dimensional array.

# Example 1 - working (change this)
x= torch.tensor([[1, 2], [3, 4.]])
x

Tensors can have any number of dimensions, and different lengths along each dimension.
We can inspect the length along each dimension using the .shape property of a tensor.
