Introduction
In this article, we will explore a new feature within GitHub Co-pilot called GitHub Compiler Labs. This Visual Studio Code extension allows us to analyze existing notebooks and ask Co-pilot questions about the code to better understand it. Specifically, we will be working with a PyTorch computer vision notebook that focuses on image classification. This feature simplifies the learning process and provides a handy companion when reading new code.
Installing the GitHub Compiler Labs Extension
To get started, we need to install the GitHub Compiler Labs extension in Visual Studio Code. Open VS Code and navigate to the Extensions tab. Search for "GitHub Compiler Labs" and click on it to install. Please note that an active GitHub Co-pilot subscription is required, which can be obtained for free for 60 days with any GitHub account.
Analyzing a PyTorch Computer Vision Notebook
In this section, we will analyze different parts of a PyTorch computer vision notebook using the GitHub Compiler Labs extension.
3.1 Explaining Code Imports
Let's start by understanding the code imports in the notebook. Co-pilot can help us understand what each import does. Simply highlight the code and click on the "Explain code" button. Co-pilot will provide an explanation of the import and its functionality.
3.2 Augmenting and Normalizing Data
Next, let's explore the code that augments and normalizes the data for validation. Co-pilot can explain the purpose of each transformation function, such as random resizing, cropping, and flipping. It also explains the normalization process using the given mean and standard deviation.
3.3 Directory of the Data
The notebook refers to a directory of the data used for training and validation. Co-pilot can help us understand how the directory is defined and how the data is loaded into the notebook.
3.4 Creating Data Loaders
In this section, Co-pilot can explain how data loaders are created using the loaded data. It clarifies the purpose and functionality of the data loaders and how they enable batch processing and shuffling of the data.
3.5 Visualizing Input Data
Co-pilot can guide us through the code that visualizes the input data. It explains how the input images are transformed into tensors, normalized, and displayed using the torch Vision Package.
3.6 Training the Model
Now let's explore the code responsible for training the model. Co-pilot can explain the function that trains the model and its arguments, such as the model itself, the loss function, the optimizer, the learning rate scheduler, and the number of epochs.
3.7 Visualizing Predictions
Lastly, let's analyze the code that visualizes the predictions made by the trained model. Co-pilot can explain how the model's mode is set to evaluation mode, how the class probabilities are obtained, and how the images with predicted labels are displayed.
Building and Training the Model
This section focuses on the code for building and training the model. Co-pilot can explain the process of loading a pre-trained model, setting parameters, defining the loss function, selecting an optimizer, and running the model. The training process, including the number of epochs, loss values, and accuracy, can also be explained using Co-pilot.
Conclusion
In this article, we explored the GitHub Compiler Labs extension within GitHub Co-pilot. We learned how to install the extension and analyze a PyTorch computer vision notebook step by step. Co-pilot proved to be a helpful tool in understanding the code and its functionality. By leveraging this extension, developers can enhance their learning experience and gain a deeper understanding of complex topics like AI and computer vision.
