SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Build ExecuTorch from source across Python packaging, C++ runtime, runners, and backends, enabling reproducible builds and platform-specific deployments.

Core Features & Use Cases

  • End-to-end source build: Python package installation, C++ runtime, and runner binaries
  • Cross-platform preparation: Android, iOS/macOS frameworks, and Linux backends
  • Diagnostics and setup: guided checks to diagnose and fix common build failures
  • Use case: setting up a clean development environment for a new machine to compile ExecuTorch for a target platform

Quick Start

Run the built-in installer to configure and perform a platform-specific build of ExecuTorch.

FAQPage Schema
How do I build ExecuTorch from source for C++ runtime and Python packaging?

Building ExecuTorch from source requires satisfying prerequisite checks, setting up the environment via conda or virtualenv, running CMake configurations, and synchronizing submodules to compile Python packaging and C++ runtime.

Can I cross-compile ExecuTorch for Android and iOS frameworks?

Cross-compiling ExecuTorch is supported for mobile targets, enabling platform-specific preparation for Android, iOS/macOS frameworks, and Linux backends.

What is the best way to set up a clean development environment for ExecuTorch compilation?

Setting up a clean development environment for ExecuTorch compilation involves running a built-in installer to configure prerequisites, establish conda or virtualenv environments, and execute platform-specific builds.

Why does my CMake configuration fail when building ExecuTorch from source?

CMake configuration failures when building ExecuTorch from source typically result from missing prerequisites or misconfigured environments, which can be diagnosed using guided checks to fix platform-specific issues.

Does ExecuTorch source build work on Windows and macOS?

The ExecuTorch source build supports macOS, Linux, and Windows targets, allowing developers to configure reproducible builds and execute platform-specific deployments.

Do I need conda or virtualenv to compile the ExecuTorch Python package?

Using conda or virtualenv is necessary for environment setup to compile the ExecuTorch Python package, ensuring proper dependency isolation and satisfying prerequisite checks.
