Installing numba for python

Question

I am trying to install numba for python but after following the instruction from the homepage I got this error that the extension_types page can not be found.

I would very appreciate if someone knows what I am doing wrong or if I missed something that I should install.

Thank you very much in advance.

EDIT: I installed numba via:

git clone https://github.com/numba/numba.git
cd numba
python setup.py install

When I try to install it via pip, I get the following error:

Answer 1

I hope you are on Linux and you have pip installed. On my Debian Linux, I can easily install numba by following commands:

sudo apt-get install build-essential
sudo apt-get install llvm
pip install llvmpy
pip install cython
pip install numba

Then you are done!

I had the same issue and for me the solution was upgrading distribute to 0.6.45.
