Hi, getting the following error when trying to run the hotgym example with pandavis (runs fine without pandavis). Can you please advise?

File “/Users/soubhikchatterjee/.local/lib/python3.7/site-packages/HTMpandaVis-0.1-py3.7.egg/pandaBaker/pandaBaker.py”, line 56, in PrepareDatabase
self.db.Insert(tableName, regionName,regionInstance[0], json.dumps(regionInstance[1].getParameters()))

Hello, please this kind of problems post as issues in github repository.
Anyway, it seems that you have pretty old pandaVis version (0.1) package, but current is 1.0.

I have installed Pandavis from this repository. Please advise how to get the current version.

as discussed in htm-community/htm.core#748

Rework of vis to use SQLite3 database.

Hi all,
First of thanks for the contribution of pandaVis, I would like to use the visualizations of the l2l4l6a experiment for a study project.

When running experiment1.py of the 2d object modelling project with the setting self.bakePandaData = True (line 72), I get the error
Exception: Missing command method: saveConnectionsToFile

    raise Exception('Missing command method: ' + methodName)
Exception: Missing command method: saveConnectionsToFile

in the current htm.core repository the region py.GridCellLocationRegion doesn't implement the saveConnectionsToFile Method (executed here).

I assume implementing the method and saving the right connections will fix this problem and I will try changing the code in these classes to implement the method.
But as I'm not super familiar with all the htm.core bindings & stuff yet I was wondering if there is a workaround for that you (@Zbysekz) used for the visualization in your video

Best,
Felix

Hi @Zbysekz , this looks really awesome! 👍 Congratulations!
And thanks for bringing the project under the htm-community umbrella.

A few suggestions as I'm going to test this proj:

• you could put the requirements (along with the minimal supported versions) to a requirements.txt file for easier install
• would you like to make a PR to htm.core Readme with a section
