Error in Example "Modelling the diurnal cycle"

[bigsuicideparty]

I ran into a few issues with example "Modelling the diurnal cycle"

I was not able to import comets as c, so I changed it to import cometspy as c

After running the script

simulation = c.comets(layout, sim_params) gave me [ValueError: the initial pop of a model is outside of layout.grid. Either increase layout.grid or adjust COBRAModel's initial_pop]()

Any idea what might be the issue?

Did you install comets? You can get it at runcomets.org.

If you did install comets, this error seems like you are assigning biomass to a nonexisting point in the grid. For example, if the grid was 1x1 points, you assigned biomass to point x=5 y=3 or so. Make sure that your point in a 1x1 grid is (0,0).
