Python Question

Error installing Numba on OS X

I'm unable to install Numba (via pip) on my OS X system.

I'm using


  • Python: 2.7.11 (Homebrew)

  • pip: 8.1.1

  • setuptools: 20.6.7

  • OS X: 10.11.4 (x86_64)

  • Xcode: 7.3

  • Xcode CLT: 7.3.0.0.1.1457485338

  • Clang: 7.3 build 703



and have installed the prerequisites (I think) with

brew install llvm
git clone https://github.com/numba/llvmlite
cd llvmlite
LLVM_CONFIG=/usr/local/opt/llvm/bin/llvm-config python setup.py install
cd ..
rm -rf llvmlite


and also tried

brew install llvm
brew link --force llvm # later: brew unlink llvm
cd /usr/local/Cellar/llvm/X.X.X/include/llvm/Config/ # X.X.X = 3.6.2
ln -s llvm-config.h config.h


but I then

pip install numba


gives

Failed building wheel for llvmlite
Running setup.py clean for llvmlite
Successfully built numba
Failed to build llvmlite
Installing collected packages: llvmlite, numba

I'm stumped about how to proceed (without Conda!) and wonder if there's some simple fix I'm missing.

Answer

Here's what worked for me (with Homebrew Python on OS X 10.11.4):

brew install homebrew/versions/llvm37 --with-rtti
git clone https://github.com/numba/llvmlite
cd llvmlite
LLVM_CONFIG=/usr/local/Cellar/llvm37/3.7.1/bin/llvm-config-3.7 python setup.py install
LLVM_CONFIG=/usr/local/Cellar/llvm37/3.7.1/bin/llvm-config-3.7 pip install numba
rm -rf llvmlite
