-### CMake Installation Rules - -The CMakeLists.txt now includes minimal installation rules that: -- Install only essential files for the wheel -- Exclude large documentation and media files -- Ensure self-contained packages -- Follow the pattern from `ffi/CMakeLists.txt` - -## Benefits of Migration - -### ✅ For Developers -- **Editable Installs**: `pip install -e .` works seamlessly -- **Modern Standards**: Follows PEP 517/518 -- **Better Integration**: Leverages existing CMake infrastructure -- **Faster Development**: No need to reinstall after Python code changes - -### ✅ For Users -- **Version-Agnostic Wheels**: Single wheel works across Python versions -- **Self-Contained**: All dependencies included in wheel -- **Consistent Installation**: Standard `pip install tvm` workflow -- **Better Performance**: Optimized C++ compilation - -### ✅ For CI/CD -- **Simplified Builds**: Single build system for all platforms -- **Reproducible**: Deterministic builds via CMake -- **Easier Maintenance**: One configuration file instead of multiple -- **Better Testing**: Integrated build and test workflow - -## Testing Results - -### ✅ Verified Functionality -1. **Editable Install**: `pip install -e .` ✅ -2. **Package Import**: `import tvm` ✅ -3. **Basic Operations**: NDArray creation, device management ✅ -4. **Wheel Building**: `pip wheel -w dist .` ✅ -5. **Wheel Installation**: `pip install tvm-*.whl` ✅ -6. **Source Distribution**: `python -m build --sdist` ✅ - -### ✅ Wheel Characteristics -- **Format**: `tvm-0.16.0.dev0-py3-none-linux_x86_64.whl` -- **Python Version**: `py3-none-any` (version-agnostic) -- **Self-Contained**: Includes all necessary libraries -- **Size**: Optimized (excludes unnecessary files) -

-# Verify configuration -python verify_build.py -``` - -## Migration Checklist - -### ✅ Completed -- [x] Create `pyproject.toml` with scikit-build-core -- [x] Configure CMake install rules for Python package -- [x] Ensure minimal wheel size (exclude docs/media) -- [x] Test editable installs -- [x] Test wheel building -- [x] Test wheel installation -- [x] Verify Python version-agnostic wheels -- [x] Create comprehensive documentation -- [x] Create testing scripts - -### 🔄 Next Steps -- [ ] Test with different Python versions (3.8, 3.9, 3.10, 3.11, 3.12) -- [ ] Test with different platforms (Linux, macOS, Windows) -- [ ] Update CI/CD pipelines -- [ ] Remove `python/setup.py` -- [ ] Update `mlc-ai/package` for version-agnostic wheels -- [ ] Performance testing and optimization - -## Technical Details - -### Build Process -1. **scikit-build-core** reads `pyproject.toml` -2. **CMake** compiles C++ components -3. **Install Rules** place files in correct locations -4. **Wheel Creation** packages everything together -

-## Package Structure - -The built package includes: -- Python source files (`tvm/`) -- Compiled shared libraries (`libtvm.so`, `libtvm_runtime.so`) -- Third-party dependencies (CUTLASS, FlashAttention, etc.) -- Header files and CMake configuration -- Documentation and licenses - -## Development Workflow - -1. **Clone the repository** - ```bash - git clone https://github.com/apache/tvm.git - cd tvm - ``` - -2. **Install in editable mode** - ```bash - pip install -e . - ``` - -3. **Make changes to Python code** - - Changes are immediately available without reinstallation - -4. **Make changes to C++ code** - - Rebuild is required: `pip install -e . --force-reinstall` - -5. **Test your changes** - ```bash - python test_installation.py - ``` - -## Troubleshooting - -### Common Issues - -1. **CMake not found** - ```bash - # Install CMake - pip install cmake - # Or use system package manager - sudo apt install cmake # Ubuntu/Debian - brew install cmake # macOS - ``` - -2. **Compiler not found** - - Ensure you have a C++ compiler installed - - On Windows, install Visual Studio Build Tools - - On macOS, install Xcode Command Line Tools - -3. **Build fails with CUDA** - - Ensure CUDA toolkit is properly installed - - Set `CMAKE_ARGS="-DUSE_CUDA=ON"` - - Check CUDA version compatibility - -4. **Import error after installation** - ```bash - # Check if package is installed - pip list | grep tvm - - # Try reinstalling - pip install -e . --force-reinstall - ``` - -### Debug Build - -For debugging build issues: - -```bash -# Enable verbose output -export SKBUILD_VERBOSE=1 - -# Install with debug info -pip install -e . --verbose -``` - -## Migration from setup.py - -The old `setup.py` workflow has been replaced: - -| Old (setup.py) | New (pyproject.toml) | -|----------------|----------------------| -| `python setup.py install` | `pip install .` | -| `python setup.py develop` | `pip install -e .` | -| `python setup.py bdist_wheel` | `pip wheel -w dist .` | -| `python setup.py sdist` | `pip install build && python -m build` | - -## Contributing - -When contributing to TVM: - -1. **Use the new build system** - Don't modify `setup.py` -2. **Test your changes** - Run `python test_installation.py` -3. **Update dependencies** - Modify `pyproject.toml` if needed -4. **Follow Python packaging best practices** -
