Re: [UrbanSim-Users] custom gridcell variables and estimation

Hana,

Somehow, we did not have an __init__.py file in our gridcell directory
(that was stupid of us). However, once we put one in place, we still
had the error.

I realized that we were importing "variable_functions" without out
fully qualifying the package (i.e. we weren't importing
urbansim.gridcell.variable_functions and didn't have a local copy of
the class).

Sadly, the error message for these two different problems are the same.

If there's some way to differentiate these error conditions, it would
be helpful to have specific error messages, but it's probably not an
urgent problem.

Thanks,

Brian
