Glimpse- Visualizing attentional focus and atomspace

[Vishnu Priya]

Hello all,

Currently i am stimulating atoms and trying "Glimpse" for visualization. 

I have started REST API, successfully connected to localhost:9000 and i am able to see Glimpse GUI. (i have also attached some pics).

But i don't know how to visualize my atomspace and Attentional Focus. 

Please provide me the steps to do so.

Thanks,

Vishnu

Hi,  I don't think the command 'node index.js' is properly rendering the visualizer. Instead, type 'npm start' which should work according to the README. Next, you need to load the ECAN module by telneting to the cogserver first and then typing  loadmodule ./opencog/attention/libattention.so. While you are still the opencog shell, type  start-ecan to start the ECAN agents. After that, you can either directly stimulate atoms via (cog-stimulate ATOM) or insert atoms with AV values. Furthermore, look into this wiki page http://wiki.opencog.org/w/Hands_On_with_Attention_Allocation.

 Thanks for the quick reply Misgana. I have exactly done as what you said.  

npm start

load ...libattention.so..

start ecan

So what could be the problem?

[Misgana Bayetta]

I just checked it and it works for me.

May be you have the wrong version of angular js.

[Vishnu Priya]

I forgot to tell you, when i run "npm test ", it throws an error. 

 

[Vishnu Priya]

Which version of angular js should i have. Or how to check it?

Older version of angular js worked for me. 

 In index.html, i made the following changes and it worked. 

<!--script type="application/javascript" src="libs/angular/angular.min.js"></script-->

    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

Instead of localhost:5000, i tried connecting to localhost 17004, to visualize my atomspace. But it said "Error connecting to Server".

What do i miss here? 

[Misgana Bayetta]

You need to start the REST API and by default, it runs on port 500 I guess. Here is the wiki link on how to start  it http://wiki.opencog.org/w/REST_API

port 5000, not 500. Anyways, you don't have to change that.

[Vishnu Priya]

Yes Misgana. I got it working for the first few times. And afterwards,  it always said  "successfully fetched 0 atoms".  REST windows is running continuously showing status 200. But also sometimes rarely ends up in SIGPIPE error.

When i made a curl request,  curl 'http://localhost:5000/api/v1.1/atoms?type=ConceptNode',  before creating atoms, it also returns something. This seems fishy. ???

i expect that to be empty.  

I just did the following steps in this order:

1. Start npm

2. telnet and connect to cogserver (17004)

3. start REST

4. in the cogserver, create some atoms

5. goto localhost 9000 and connect to 5000

I have attached the pics for your reference.

Many Thanks,

Vishnu
