Getting Segmentation Fault error while trying execute scheme code using the python api

[Xabush Semrie]

I have MOSES training results in scheme format that is I want to import to the atomspace. I am using the OpenCog python api to access the atomsapce and import the results, However, in trying to do I am getting "Segmentation fault (core dumped)" error. To demonstrate what I am trying to do, here is a snippet of code I am using.

from opencog.scheme_wrapper import scheme_eval, scheme_eval_as

atomspace = scheme_eval_as('(cog-atomspace)')



with open('/path/to/the/result_file', 'r') as fp:
 scm = fp.read()
response = scheme_eval(atomspace, scm) #this is line is the cause of the error.

When I instantiate the atomspace using its constructor, the above error does NOT happen. The problem in instantiating the atomspace through the constructor is that I cannot get response when I use the atomspace instance with the OpenCog REST API. What can be the cause this error? How can I resolve it?

P.S: I have attached the results file so that you can take a look at it.

Thanks in advance.

Is this still an issue?

I just tried it; using "foo.scm"   which contained:

(use-modules (opencog))

(Concept "foobar")

(display "ollllaaa\n")

(Concept "barfoo")

I got no error, and this output:

>>> response = scheme_eval(atomspace, scm)
>>> print response
ollllaaa
#<Invalid handle>

You probably should open a github issue to track this.

I tried using your example and still getting the same error. For clarity here is what I tried to run in python:

from opencog.scheme_wrapper import scheme_eval, scheme_eval_as


atomspace = scheme_eval_as('(cog-atomspace)')

with open('foo.scm', 'r') as fp:
 scm = fp.read()


response = scheme_eval(atomspace, scm) #Segfault occurs here

And also, I will post an issue on the OpenCog repo.
