how to convert image to tensor in pytorch

Sure, I'd be happy to help with that! Converting an image to a PyTorch tensor involves a few steps, such as loading the image, preprocessing it, and then converting it to a tensor. Here's a step-by-step tutorial with a code example:
Before starting, make sure you have PyTorch installed. You'll also need some additional libraries for image handling.
In this example, the image is resized to a size of (224, 224) as required by many pre-trained models. ToTensor() converts the image to a PyTorch tensor, and Normalize() normalizes the tensor values using specified mean and standard deviation values. The mean and standard deviation values used here are typical for models pretrained on ImageNet.
You can check the shape and data type of the converted tensor:
This code can be used as a template to convert your own images to tensors in PyTorch, allowing you to use them as inputs to neural networks or other PyTorch-based models.
