htm-community / htm-school-viz Goto Github PK

Even though the videos are already online, Matt, will you update the code to play with them?

For ep.10, I get to choose a moving gif, and that's it.
For 11 there's any empty window.

Hi,
I installed the nupic-history-server and have it running on port 8000 with the command "redis-server --port 8000". Then I attempted to start the htm-school-viz with "npm start 8080". The firewall is disabled and I installed the dependencies with "npm install --user".
The npm error log follows:

npm-debug.log.txt

Related to #9 - but not the same issue.

• I fixed redis to run on expected port 8000 htm-community/nupic-history-server#9
• there I also had to update the dependencies
• you've used some local build 0.5.7.dev0 and 0.4.13.dev0, which are not available
• tested with both: stable (0.5.7 and 0.4.13), and latest (just nupic, nupic.bindings in requirements)

And I get the same error:

(schools) mmm@mmm-U2442:/mnt/store/devel/HTM/htm_schools/htm-school-viz$ npm start 8080

> [email protected] start /mnt/store/devel/HTM/htm_schools/htm-school-viz
> node index.js "8080"

The screen is stuck on a "loading" circle

I started this project with a Python server so I could run NuPIC on the server. Since then, I have moved all that to another server, so this project can be converted to 100% JS.

This task is to remove server.py and replace with index.js that does exactly the same thing.

@rhyolight Hello Matt,

sorry for reaching for you this way, I couldn't get in touch on Gitter..
Could you please help me with 2D spatial pooler in C++? Similar as you've been using in the topology episodes here.

Say I have input board 100x100, and SP 32x32, I want to select some input positions ({{99,0}, {0,0}, {0,99}}) and then let the SP compute. I know how to make a 2D SP:

SpatialPooler sp{vector<int>{100, 100} /*input dims*/, vector<int>{32, 32} /*cols*/,...};

But I don't know how to format the input 1D vector for compute(), it should be a dense, binary 1d vector, but I don't know how the 2d is translated to 1d here.
Thank you very much!

I have downloaded the numenta/nupic docker and installed nodeJS 8.x on it. After running npm install and then npm start 8001, I can access the site at localhost:8001, but when I click on Episode 7 I never get past the loading GIF, and I get the error in the console:

POST http://localhost:8001/_proxy/_sp/ 404 (Not Found)

Some of the other episodes work fine, example: Episode 6. The 404 error returned is returned by Nginx.

I have not gotten any visualization to work yet. Throwing some javascript errors in the console. But at least it displays a webpage!

I can get all the other samples to load and run just fine however. I've attached a screenshot that shows the console error message. Something about a _proxy call failing.
