PYMC and pythonxy

[Jan Kraus]

Did anyone succeded to install and run pymc for python(x,y).

I tried the recommended 'easy_install pymc' method but even after
installation in win32 I can not import the package in python console.
As a complete numb to windows python packaging I would be glad for any
help.

I am not even able to provide the result of easy install as it opens/
closes its console itself.

Could not reproduce - pymc install without a problem using easy_install.

It's much easier to use the binary installer:

http://pypi.python.org/packages/2.7/p/pymc/pymc-2.2.win32-py2.7.exe#md5=d63c53afd042d080c773fe06a639b3ab

the "easy_install" command must be entered from the "command prompt" to be able to capture the input.

Thanks Gabi.

 

PyMC is now installed, however another problem has occured.

 

When I import pymc I get the following error:

 

ImportError: DLL load failed: the specified module could not be found.

 

Any ideas?

Sorry Gabi. I'm new to this and I'm not what you would call a programmer. Anyway lets try again.

 

I'm using windows 7 and Python(x,y) 2.7.2.3.

I normally use IPython and below is what is printed out on the IPython console if I type import pymc:

 

In [1]:    import pymc

Hi,

I'm revisiting this issue. Has anybody figured out how to get PyMC working with Pyhton(x,y)?

Any help would be appreciated.

Kind regards

Brendon

Have you tries gohike's binaries?

Ok I think I have a solution.

1. Download and unpack PyMC.

2. From the command line change the directory to where you unpacked your PyMC.

3. Then in the command line type the following command.

python setup.py build install build --compiler=mingw32

I had issues with PYMC version 2.x on PyPi related to it wanting to import components coded in Fortran, more luck with easy-install of the PYMC 3.0 package from here:

https://github.com/pymc-devs/pymc

The newer version doesn't depend on Fortran code, but you will need to get Theano installed (Theano being a sort of compiler of equations). Installing Theano
was easy for me, but maybe I'm just lucky.
