How to Use PyTorch

Install PyTorch: Select your preferences and run the install command from pytorch.org. For example, using conda: 'conda install pytorch torchvision -c pytorch'
Import PyTorch: In your Python script, import PyTorch: 'import torch'
Create tensors: Create PyTorch tensors to store and operate on data: 'x = torch.tensor([1, 2, 3])'
Build a neural network: Define your neural network architecture using torch.nn modules
Prepare data: Load and preprocess your dataset, typically using torch.utils.data
Train the model: Implement the training loop - forward pass, loss calculation, backpropagation, and optimization
Evaluate the model: Test your trained model on validation/test data to assess performance
Save and load the model: Save your trained model using torch.save() and load it later with torch.load()
Deploy the model: Use TorchScript or TorchServe to deploy your model for production use

PyTorch Monthly Traffic Trends

PyTorch experienced a 2.7M visits with a -8.7% decline in traffic. The recent switch to the new wheel build platform manylinux-2.28 and the release of the 2024 roadmap did not significantly impact traffic, suggesting that these updates may not have been the primary drivers of user engagement. The PyTorch Conference 2024 in September, which featured advancements in PyTorch 2.4 and Llama 3.1, also did not seem to boost traffic.
