python-pytorchHow do I use Python, PyTorch, and CUDA to optimize my code?
Using Python, PyTorch, and CUDA together is a powerful combination that can help optimize code. The following example code block demonstrates how to use CUDA with PyTorch to speed up a simple matrix multiplication operation:
import torch
import torch.cuda
# Create two matrices
a = torch.randn(1000, 1000).cuda()
b = torch.randn(1000, 1000).cuda()
# Multiply the matrices
c = torch.mm(a, b)
# Print the result
print(c)
The output of this code will be a 1000x1000 matrix, which will be computed using CUDA and thus be much faster than a CPU-only operation.
The code can be broken down into the following parts:
- Import the necessary libraries:
import torch
andimport torch.cuda
. - Create two matrices,
a
andb
, and assign them to GPU memory using the.cuda()
method. - Multiply the matrices using the
torch.mm()
method. - Print the result using the
print()
method.
For more information on how to use CUDA with PyTorch, please refer to the PyTorch Documentation.
