Hello!! I'm here to guide you guys on how to install numba on mac os x. Numba is a tool to speed up python applications with just annotations.

It should be easy as pip install numba, but I don't know why it does not solve all the dependencies, and I don't know why I spend so much time on it... :/

Numba depends on llvm llvm, a umbrella project that includes a bunch of compilers and low-level tools. You can install it with Homebrew.

$ brew install llvm

Then you need to link some env vars with brew link and create a symbolic link that is necessary to install llvmlite (a numba dependency).

$ brew link llvm
$ ln -s /usr/local/Cellar/llvm/<llvm_version>/include/llvm/Config/llvm-config.h config.h

You can check the llvm version installed with brew info llvm.

Finally, we can install numba. Remember to unlink llvm vars, so that it don't mess up with os x llvm.

$ pip install numba
$ brew unlink llvm
