That’s great! Feel free to update the wiki, I have not finished it.

I wanted to just run the basic swarm from the swarm tutorial…
I am getting a segmentation fault. Installed Nupic and Nupic.core properly and ran make successfully.
not sure whats wrong. but this should be pretty straightforward

The next time I ran it with --overwrite option I see the same core dump

After a series of git commits on the 22nd, I was able to build nupic.core with no issues in ubuntu. I was having the exact same issues. I was also getting segfaults running the swarm using the pip installation. After building everything the swarm ran fine in the sine prediction tutorial.
