PyStan 0.1.1 on the Python Package Index

[Allen Riddell]

PyStan 0.1.1 is up on the Python Package Index (Python's CRAN).

https://pypi.python.org/pypi/pystan

Sampling works fine under Python 2.7 and Python 3.3. It's still alpha though;
there are a number of things to be implemented, such as reading/writing to csv.

I'm having some trouble. I eventually got python3 versions of all the dependencies installed, which allowed it to build

running install_egg_info
Writing /usr/local/lib/python3.3/dist-packages/pystan-0.1.1.egg-info
running install_clib
creating /usr/local/lib/python3.3/dist-packages/pystan/bin
copying build/temp.linux-x86_64-3.3/libstan.a -> /usr/local/lib/python3.3/dist-packages/pystan/bin/

root@CYBERPOWERPC:/tmp/pystan# updatedb
root@CYBERPOWERPC:/tmp/pystan# mlocate -b pystan
/usr/local/lib/python3.3/dist-packages/pystan
/usr/local/lib/python3.3/dist-packages/pystan-0.1.1.egg-info

But it doesn't work for me when I try it

Hi Ben,

I think you may need to change out directory you extracted pystan into. Likely
Python is trying to import pystan._api from your immediate directory rather
than from the installed directory.

Best,

Allen

Ok, it is working now.

Thanks,
