How do you install blaze natively (i.e., not in a virtual environment) in Python? The only instructions I find are on in the package's doc (see link), and here, in a virtual environment.

I didn't find any instructions anywhere online for this, but it's relatively straightforward.
About my platform/tools I used:
- Mac OSX (Mountain Lion)
- Python 2.7.3
- homebrew
- pip
- It looks like you might need to install Cython, not sure as I already had it installed. You can do this with
pip install Cython
.
First, brew install llvm
.
Here are the packages you need. You can pip
all of them:
llvmpy
numba
meta
ply
blosc
sphinx
-- for docaterm
Once you've pipped everything,
cd /tmp
up to you, of course...sudo git clone git@github.com:ContinuumIO/blaze-core.git
cd /tmp/blaze-core
sudo make build
sudo make docs
sudo python setup.py install
(Whether you need sudo depends on where you git things to, of course.)
I've had trouble running the tests, it looks like there's an error in an __init__.py
file somewhere, but I can't be for sure. I can't get the unit tests to run, so take "successful installation" with a grain of salt. At any rate, I can do a spot check to see that the module imports correctly:
>>> import blaze
>>> from blaze import Array, dshape
>>> ds=dshape('2,2,int')
>>> a = Array([1,2,3,4],ds)
>>> a
Array
datashape := 2, 2, int
values := [CArray(ptr=140454075688080)]
metadata := [manifest, arraylike]
layout := Chunked(dim=0)
[1 2 3 4]
