Re: [UrbanSim-Users] using mysql for estimation input

Fabrice,

You need to first create a cache directory (with
opus_core/tools/create_baseyear_cache.py), set the 'cache_directory' in
my_configuration to that directory and run the estimation. The
input_configuration is included in order to be able to use that
configuration file as an argument for create_baseyear_cache.py.
