Issue

The current build process lacks portability and reproducibility. This makes it harder to collaborate.

By following the build instructions in the CONTRIBUTING.md file, I noticed that the setup.py script is using the same system default compiler for both C and C++ code (e.g., clang on macOS) which breaks the process on MacOS.

After configuring the right compilers per language via the environment variables I noticed that the code isn't portable and breaks on ARM architectures.

Proposed Solution

To enhance portability, reproducibility, and overall project quality, I propose implementing architecture-dependent Docker containers for the build process. This approach will:

  1. Ensure consistent build environments across different architectures
  2. Simplify the build process for contributors
  3. Improve the project's compatibility with a wider range of systems

Benefits

  • Increased portability across different architectures, especially ARM
  • Enhanced reproducibility of builds
  • Simplified onboarding for new contributors
  • Expanded reach of the project to more diverse hardware platforms

Implementation Details

Create Docker containers for each supported architecture.

Testing

I have tested this solution on the following system:

  • macOS 14.6.1 23G93 arm64, Mac14,10 (Kernel: 23.6.0) (Apple M2 Pro)

Additional testing on other architectures is recommended before merging.

Hi @sueszli , thanks for the PR.

Sorry, adding docker-based build systems won't be in scope for torchvision.

I understand - Out of curiosity, may I ask why?

It's because the torchvision builds and release system is based on that of pytorch. Basically it relies on https://github.com/pytorch/test-infra/ and https://github.com/pytorch/builder.
