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

The main objective of this exercise is to create an inference script for an ONNX image classification model.

Fill in the missing code in each of the interactive playgrounds. Replace all the `<CODE>` placeholders with the correct code.

You can click on the “Show Answer” button below each playground to reveal the answer.

# Import
Start by adding all the necessary import statements at the top of the inference script:
* ONNX Runtime
* Python Imaging Library
* NumPy

Practice performing the model conversion process behind the PyTorch Image Model.
