View MoreHow 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
