Re: [UrbanSim-Users] MySql configuration

Mark,

In fact the file to modify is
urbansim/configs/general_configuration_with_changed_elcm.py but not
urbansim/configs/general_configuration.py (check the
eugene/configs/baseline.py, it import the first one).

I tryed also to add the parameter "Sampler"="None" : the following warnings
no more appear (ok) but we have the same last Error.

                        WARNING: weight_array sums to 0 or less
                        WARNING: weight array dosen't have enough non-zero
counts, use sample with replacement
                        WARNING: prob_array doesn't sum up to 1, and is
normalized.

Hana, I work with Mark but I'm not near him.

I continue to have a look on this.

Regards,
Philippe.

  Hana,

  Unfortunately, I have errors for ELCM again.

  For "sample_size_location" equals to either 10 or 5 or 3:

  WARNING: weight_array sums to 0 or less

  WARNING: weight array dosen't have enough non-zero counts, use sample with
replacement

  WARNING: prob_array doesn't sum up to 1, and is normalized.

  For "sample_size_location" equals to None:

  WARNING: Neither 'sample_proportion_locations' nor 'sample_size_locations'
given. Locations will not be sampled.

  In annual_employment_control_totals table there is sector_id equals to 6.
This number 6 is absent in our dataset. Could it be the reason of the error?

  Mark
