Getting "Aborted (core dumped)" when trying to make queries

[lucasvittal2]

I've made every step given by "Quick Start" until finally I got the models(pickle files) and accessing the discovery API, when I execute the following command lines:

from main import init_system
api, reporting = init_system(<path_to_serialized_model>, create_reporting=False)

api,reporting = init_system('/home/admin/Desktop/Aurum/aurum-datadiscovery-master/data/models/',True)

The API is started, and from now, the SQRL language is been used to make queries :

with the models that were got from the datasets I've provided. However, when I try to make queries , following the "Aurum - data discovery system" paper at section IV - "Querying the EKG":

In : results = schemaSearch("sepal_length","sepal_width")

I'm getting the following log:

free(): invalid pointer
Aborted (core dumped)

it means that some attempt to access forbidden memory area was done, but I don't know why it is occurring and how to solve this problem, it's very strict to Aurum data discovery system and just someone that is familiarized with Aurum could answer my questions. Could someone who already used the queries give some help I'd appreciate a lot.
Thanks!

This is a new one! I wonder if it's related to running from a notebook/ipython which is not installed inside the virtualenvironment you are using? In other words, I'd install ipython inside the virtualenv, and then run that instance of ipython and see if the problem persists. It's the first time I see/hear this problem, thanks for reporting!
