python-pytorchHow do I install and use the Python PyTorch package?

1. First, you need to install PyTorch. You can do this by running the following command in your terminal: pip install torch torchvision

2. Next, you need to import the package in your python script. You can do this by adding the following line to the top of your script: import torch

3. Once you have imported the package, you can use it to create tensors. A tensor is a multi-dimensional array. Here is an example of how to create a tensor:

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

Output example

tensor([[1, 2, 3], [4, 5, 6]])

4. You can also use PyTorch to perform various mathematical operations on tensors. For example, you can add two tensors together using the torch.add() function:

x = torch.tensor([[1,2,3],[4,5,6]])
y = torch.tensor([[7,8,9],[10,11,12]])
z = torch.add(x,y)
print(z)

Output example

tensor([[ 8, 10, 12], [14, 16, 18]])

5. PyTorch also provides a variety of other features, such as support for deep learning and GPU acceleration. You can find more information about the features of PyTorch in the documentation.

6. You can also find tutorials and examples of how to use PyTorch on the PyTorch website.

7. Finally, if you need help with any PyTorch related issues, you can ask for help on the PyTorch forums.
