Hi Katrina,
Although you are running SyncroSim from python, the helloworldTime SyncroSim Package is built using an R script and requires the R package rsyncrosim to be installed. I realize that having to install an R package to run the pysyncrosim tutorial is a bit strange. We will update the tutorial in the next week, but in the meantime you can get the scenario to run by first installing the rsyncrosim package in R using: install.packages("rsyncrosim").
Cheers,
Katie
