Pre-trained ResNet models for image recognition in PyTorch.

ResNet models in PyTorch's `torchvision` library provide pre-trained deep learning architectures for image recognition tasks. These models, including ResNet18, ResNet34, ResNet50, ResNet101, and ResNet152, are trained on the ImageNet dataset. The architecture leverages residual connections to mitigate the vanishing gradient problem, enabling the training of deeper networks. The models expect mini-batches of 3-channel RGB images normalized with specified mean and standard deviation. Use cases include image classification, feature extraction for transfer learning, and as a component in more complex vision systems. The pre-trained weights allow for rapid prototyping and deployment, offering a significant advantage in terms of training time and computational resources.

Install PyTorch and TorchVision: `pip install torch torchvision`
Import necessary libraries: `import torch` and `from torchvision import transforms, models`
Load the pre-trained ResNet model: `model = torch.hub.load('pytorch/vision:v0.10.0', 'resnet50', pretrained=True)`
Set the model to evaluation mode: `model.eval()`
Preprocess input images using `transforms.Compose` for resizing, cropping, and normalization
Convert the preprocessed image to a tensor and add a batch dimension
If GPU is available, move both input and model to CUDA
Pass the input tensor through the model to obtain the output
Apply softmax to get the probabilities for each class
Interpret the output tensor to identify the top predicted classes.
