To build coremltools from source, you require you need CMake and Miniconda to configure the project.
Our makefile & scripts require the zsh shell (default shell for macOS
10.16+) installed in /usr/bin.
The following targets will handle the development environment for you. If you need to add packages, edit the reqs/pip files and the auto-environment will install them automatically.
build| Build coremltools in debug mode (include symbols).docs| Build documentation.clean| Clean build dir.clean_envs| Delete all envs created by the scripts.lint| Linter.proto| Build coremltools and rebuild MLModel protobuf sources.release| Setup the package for release, but don’t upload to pypi. Include all wheels from build/dist in the built package.style| Style checking.test| Run all tests. Pass TEST_PACKAGES="..." to set which packages to test.test_fast| Run all fast tests.test_slow| Run all non-fast tests.wheel| Build wheels in release mode.
By default, we use python 3.7 but you can can pass python=2.7 (or 3.6, 3.8
etc.) as a argument to change the env / build / wheel python version.
Using an unmanaged developer environment
Use make env to create an auto-set-up development environment with the
correct package dependencies. This env will not be changed by scripts after
creation. However, provided scripts & makefiles do not currently support custom
development environments; rather, they will always auto-activate the managed
environment. Environments are generated and stored at
