Hi everyone,
I'm new to OpenCog. Knew about it for a few years and finally decided to
start exploring!
I'm going through the tutorials now, and I'm stuck at launching the Python
API. I could successfully run the code
in http://wiki.opencog.org/w/Getting_Started_with_Atoms_and_the_Scheme_Shell,
so I assume that at least some OpenCog modules are working properly.
However, now, when I try to launch the REST API as described
in http://wiki.opencog.org/w/Using_the_REST_API, I am getting errors.
I noticed that one of the directories that should be added to PYTHONPATH
(/usr/local/share/opencog/python) does not exist on my system. The only
directory in /usr/local/share/opencog is scm. I don't know if this is
normal.
I located start_restapi.py in /home/pavel/opencog/examples/restapi/. Upon
launching I got the error that the module 'opencog.cogserver' could not be
found. I located cogserver/cogserver.py
in /home/pavel/opencog/opencog/python/test_atomspace and added that to
PYTHONPATH. The I got this error:

This is where I'm stuck. Please help! :)
My system is Ubuntu 14.04 server.
