Error while import opencog python libraries

[Habush]

I have a docker image which uses the opencog-dev image as a base. After building the image successfully, I can't use the OpenCog python modules as I run into an import error. The docker files I am using to build the images can be found at this repo. As an example, running this simple script on the python command line raises an import error

from opencog.atomspace import AtomSpace
atomspace = AtomSpace()

The error:

ImportError: No module named opencog.atomspace

@Habush fixed by opencog/ocpkg#102

[Habush]

@amebel The error is still occurring. Also the default python version is 2.7

[amebel]

@Habush In the docker containers it is python3. Do you want a python 2 version?

[mjsduncan]

the mozi back-end currently assumes opencog is built with python 2. is there a way to force atomspace/opencog to be built with python 2 in the new cmake?

[amebel]

@mjsduncan yes it is possible

[amebel]

@Habush @mjsduncan the opencog/X images are meant only for development and not for production systems

[linas]

If a system has both python2 and python3 installed. does opencog build both versions? It probably should; they could be build in different directories, adn installed in different install locations.

[amebel]

@linas CMake is not configured to do that presently, but yes that is possible.

[mjsduncan]

fyi we've decided to bite the bullet and port mozi to python 3.

[linas]

porting to python3 should not be hard, there are several great "howto" pages out there -- its mostly just tedious, like adding extra parens to print statements, etc.
