Mac OS X works* for me if I build with python 2.6 but then run with 2.7. There is one message on startup complaining about a version mismatch but everything appears to run fine. I will write this up someday, really I will.
- Kevin * so far as I can tell, though I haven't done rigorous testing**. I only tested on hotgym and I only looked at the text output (slightly tweaked from Scott's original code. The output isn't an exact match to the corresponding output from python 2.6 on a CentOS VM, but so far as I could tell the difference was just that 2.7 was doing a better job of rounding when converting floating point to text. ** numerical regression tests would be really nice, maybe criticial if there is to be an ARM port. This is nontrivial because, well, floating point arithmetic***. I'm not even sure what the right comparison model is, but probably one would want to compare means and variances at least. *** an example of the nightmare that is validation of floating point computations: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0038234 From: nupic [mailto:[email protected]] On Behalf Of Erik Blas Sent: Monday, July 15, 2013 11:50 AM To: NuPIC general mailing list. Subject: Re: [nupic-dev] Linux Version/Distribution On linux, pyenv and pythonbrew seem to solve the build problem, regardless of python version. Only platform that's giving me trouble still is OS X.

I run Fedora 16 myself which comes standard with Python 2.7. I had to recompile Python 2.6 by myself and although everythig semmed to work well I was unable to make it work with CLA (error on undefined symbol in multiarray.so). HAs anybody experienced the same problem ?

The requirements are quite basic.

We'd like build the same environment used for NuPIC to avoid complications. Once I get that going I'd like build it in OS X, but want first to get it going as it was developed. Thanks!
