PyTorch Builder
The PyTorch Builder is a collection of scripts designed to streamline the process of building PyTorch binaries and conducting comprehensive integration tests. These scripts play a crucial role in ensuring that PyTorch is distributed across various operating systems and environments efficiently. Below is a detailed overview of the key components within the PyTorch Builder project.
Project Structure
The PyTorch Builder project is categorized into several folders, each dedicated to specific tasks related to building and distributing PyTorch packages across different platforms.
-
Conda: This folder contains a variety of files essential for building Conda packages for PyTorch, along with its library, torchvision, and other requisite dependencies. This setup ensures that users can easily install PyTorch through the Conda package manager.
-
Manywheel: This set of scripts is utilized to build PyTorch wheels specifically for Linux environments. The "wheel" is a packaging format for Python that significantly simplifies the installation process.
-
Wheel: Similar to the "manywheel" script collection for Linux, this folder contains scripts tailored to create OSX wheels. These are essential to ensure that Mac users can effortlessly install PyTorch on their machines.
-
Windows: In this section, the scripts are dedicated to building wheels compatible with Windows. This allows PyTorch to be available to the broad Windows user base seamlessly.
-
Cron: This folder houses scripts that automate and drive the execution of previously mentioned scripts across various configurations. The cron jobs are vital for keeping the building process up-to-date and running smoothly without manual intervention.
-
Analytics: The analytics scripts play a vital role in tracking the distribution and usage of PyTorch wheels by pulling down download counts from AWS S3 logs. This data is crucial for analyzing user engagement and the popularity of PyTorch releases.
Testing Process
To maintain the reliability and performance of the PyTorch Builder, robust testing procedures are in place. When builds are triggered by GitHub actions from the PyTorch repository, there are specific instructions available to guide developers in testing changes made to the PyTorch Builder scripts.
In summary, the PyTorch Builder serves as an integral part of the PyTorch ecosystem, ensuring that the binaries are built, distributed, and tested effectively across multiple platforms. By handling a wide range of configurations and packaging needs, it significantly contributes to the accessibility and ease of installation of PyTorch for developers worldwide.
