PyTorch is a machine learning framework used in a wide array of popular applications, including Tesla’s Autopilot and Pyro, Uber’s probabilistic modeling engine.

This course is an introduction to image classification using PyTorch’s computer vision models for training and tuning your own model. You’ll start with the fundamental concepts of applying machine learning and its applications to image classification before exploring the process of training your AI model. You’ll prepare data for intake by the computer vision model with image pre-processing, set up pipelines for training your model, and fine-tune the variables to improve predictive performance. You’ll finish by deploying the image classification model by converting to ONNX format and serving it via REST API.

By the end of this course, you’ll be able to build and deploy your own image classification models from scratch.

Getting Started with Image Classification with PyTorch

We can use the ONNX model for inference on our datasets.

We will use the `onnxruntime` package. It’s a cross-platform machine learning accelerator for inference and training.


# Utility functions
Define the following utility functions:
* `softmax`: This is the replacement function for `torch.nn.functional.softmax`.
* `to_numpy`: This is the function that converts the `PIL.Image` into the `numpy` array.

These functions remove the need for the `torch` and `torchvision` packages, which will keep our application minimal for deployment.
