Preloading atomspace with initial data

[Eyob]

Is it possible to have initial group of atoms to exist by default in the atomspace?

This seems to be a critical requirement in the following setting.

I have a python code that uses something like

from opencog.scheme_wrapper import load_scm, scheme_eval_h

atomspace = AtomSpace()

load_scm(atomspace,"{}/output2.scm".format(os.getcwd()))

Bascially the problem is it takes forever to load atoms in the file output2.scm from within python while using "load_scm", while it takes few seconds to do it in guile.

So, if initial atoms that are in output2.scm could have been loaded initially somehow by default, then doing  "atomspace=Atomspace( )" would load the initial set of atoms the app needs automatically,
which would help avoid using load_scm with output2.scm.

Thanks.

it's a hack but you could put (load "output2.scm") in your ~/.guile file or some other guile config file so it would automatically load when guile is invoked.  or the guile -l flag will run an arbitrary scheme file...

I don't understand the question. What do you mean "takes forever"?
Are you compiling the file? By default, when you load an scm file,
the guile compiler runs. This can take a very long time, if the file
is large. It is also a complete waste of time, if the file contains
only atoms and nothing else. It would be best to just disable
compilation -- i.e. use primitive-load instead of load

https://www.gnu.org/software/guile/manual/html_node/Loading.html

viz do not use load_scm(), it is probably mis-handling the compilation step.

The other alternative is to dump your atoms into an sql db and use
that, however, this is a bit more complex if you are not regularly
working with big data.

Linas: Yes primitive-load might be the life saver here. I will try it out. Thanks :)

Mike: Since I am running code from python, the things I put in .guile won't be accessed by the python code.

Yeah, primitive-load worked as tested by one of our team members. Loads in secs. Thanks!!!
