How to Run HTM School Visualizations

I know the problem. You’re in Windows.

Change the gifData folder to gifdata lower case d. That should fix it.

I’ll submit a fix today.

I am using Ubuntu 16.04. And yes, actually I needed to change it to capital D! Many thanks for your help.

I killed the job and relaunched ‘npm start’. I see the image options now. The only little problem is that there are no thumbnails!

I forget sometimes that OS X is not case-sensitive. There is probably a similar problem with gif file names. Look in your console for more errors

Great help. I digged through and all fixed now!

For your ready future reference, following lines need replacement
In https://github.com/htm-community/htm-school-viz/blob/master/static/js/ep10/choose-gif.js (and also in master/index.js)

Line 4

var gifData = undefined;

to

var gifdata = undefined;

Or replace-all gifdata with gifData

… Ah wait, I notice that you have fixed everything already! Great!

Hello. What a great tool, thanks!

The only thing I have problems with is gifs selection. Gifs show up for me, but when I click on them, I don’t get on http://localhost:8001/client/ep10/topology.html?load=<GIF-NAME>. I’ve inspected the element and they look like this:

I’ve tried replacing the link in <a> tag with a full one (starting with http://localhost:8001/client/ep10), but still, nothing happens when I click on it. And if I go to the page manually, everything looks fine there.

I installed this on my ubuntu-machine and when calling webpack in $CELL_VIZ, there is no dyson.js created. It generates ‘dist/cell-viz-3d-1.4.9.bundle.js’ and I am not sure to where I need to link this.

But nevertheless I was able to run the server and start some simulations. But unfortunately when running the simulation “Many GCMs” from episode 14, the menu in the right upper edge of the screen does not appear so I can’t change the settings. Do you know why this could be the case? I would love to change the settings like you do in the video.

Thanks!

I think this are old instructions. If it works, it is working.

Uncomment this line:

github.com

htm-community/htm-school-viz/blob/master/static/js/ep14/grid-cell-modules.js#L124


      
              module.activeCells = 1
              module.weight = 1
              module.visible = true
              gridCellModules.push(module)
              count++
          }
          
          let renderer = new GridCellModuleRenderer(gridCellModules)
          
          renderer.prepareRender();
          setupDatGui(gridCellModules, renderer)
          
          renderer.render(config)
          
          if (renderer.worldPoints) {
          
              renderer.onWorld('mousemove', function() {
                  renderer.renderFromWorld(config, d3.event.pageX, d3.event.pageY)
              });
          
              renderer.onOverlay('mousemove', function(_, i) {

I have some questions about the result of this tutorial ‘how-to-run-htm-school-visualizations’, I want to know after applying this steps the results will be open in my browser? and is there any way to open them in python environment and see result after run them in python?
if it is not, is there any code witch i can use it in python and see result there???

rhyolight · October 7, 2018, 2:01pm

The visualizations are not written in python. You must run a web server.

shiva · October 7, 2018, 5:18pm

hi. is there code of spatial pooling algorithm and temporal memory in this package or not?

shiva · October 7, 2018, 5:09pm

hi, i had read this tutorial but i dont understand step 1 ,that where i should use this commands, i mean in which environment i should enter this codes??
export HTM_SERVER=<
export CELL_VIZ=<
export HTM_VIZ=<
and it should be exactly with this address or not ? i should change it by my path in my computer?

rhyolight · October 7, 2018, 5:31pm

Are you in Windows? Because this probably does not run in windows.

shiva · October 7, 2018, 5:31pm

yes i am in windows 10.

rhyolight · October 7, 2018, 6:20pm

Those are just environment variables you should set in the shell.

shiva · October 13, 2018, 9:07am

I’m trying to run the visualizations on windows 10, but I have been unable to get the webserver running. When I run the code

python webserver.py 8080

I get the error

no module name capnp

and I cant find this library for windows 64 ,As an aside I already have MinGW GCC for Python as well as mingGW 64 installed. and also install nupic correctly (the version that you cited in above and in GitHub - numenta/nupic-legacy: Numenta Platform for Intelligent Computing is an implementation of Hierarchical Temporal Memory (HTM), a theory of intelligence based strictly on the neuroscience of the neocortex. ),Any help would be much appreciated.

hi @rhyolight
did the visualization work on the windows because, as I see in the comments there is a several problems in the windows

shiva · November 4, 2018, 9:12pm

hi dear matt, when i click on episode 7 (random spatial pooler) nothing loaded, can you tell me what should i do?(I run in linux (manjaro) and in python 2.7 )

rhyolight · November 5, 2018, 4:43pm

Episode 7 is the first episode that requires the NuPIC server to be running. Make sure it is running and not throwing errors.
