Tried the ./run.py python script. The csv (non plot) generated fine, yet when plotting ran into this. Tried for a while to find issue, must be too close to see it?

Results are written to an output file (default) or plotted dynamically if the --plot option is specified. NOTE: You must run ./swarm.py before this, because model parameters are required to run NuPIC. Creating model from rec-center-hour…
