I haven't fully looked through all the files you provided, but my guess is the issue is in configuring the settings file. One thing that jumps out at me is that your seed data is specified at the TAZ level -

Geographic Settings

------------------------------------------------------------------

geographies: [REGION, TRACT, TAZ]
seed_geography: TAZ

The seed is commonly the PUMA level (larger lever than the TAZ) - it looks like you are indeed using a Seed at the TAZ level - perhaps from a household survey. But my hunch is that there is a configuration issue. The warnings above the error also make me concerned that something is incorrect in the settings. Sorry I can't be of more help, but I will continue to think on it and post any other ideas that jump to mind.

I also haven't looked through all the files but as @bettinardi pointed out, TAZs cannot be set as the seed geography in this case. In PopulationSim, there can be only one meta-geography above the seed geography. Any geography can be set as the seed geography (need not be PUMA always), provided there is only one geography above it. So in this case, TRACT should be set as the seed geography. Please try setting TRACT as the seed.

@bettinardi @binnympaul Thank you so much for your suggestion. I modified the configuration setting.yaml to set TRACT as the seed geography as attached, and then it seems the current issue has been solved. However, I am still facing another error ("assert weights_df is not None") at sub_balancing.geography=TRACT model (populationsim/steps/sub_balancing.py, line 236) as follows. Do you have any idea to solve this error?

Hello, is there any one to provide some ways to solve this issue to me?

from populationsim.

I'm sorry that no one has been able to respond. In general it seems like your attempts are outside of the way we were thinking Popsim would be used. So I think Popsim is breaking because we didn't anticipate the configuration you are attempting. To fix it, I think Binny or myself or someone familiar with PopSim would need to comb through your setup / approach and fully review and try to reconfigure the approach to get it working. It's possible it's something simple, but it's hard to guess without more fully getting up to speed with what you are attempting (at least for myself - to be able to respond I would need to fully review and understand your set up). So my only real suggestion (which is not very helpful), is to try and refer back to the instructions and attempt to test re-configuring your setup closer and closer to provided examples or instructions to get it to work and then back out from there, what is different in your approach that is breaking the tool - https://activitysim.github.io/populationsim/.

Were you able to get an example to run that you can refer back to?

I also suggest you review the examples in the repository and the instructions. Your error seems to be due to an inconsistent configuration of the settings file. Complete instructions on configuring the settings file are here: https://activitysim.github.io/populationsim/application_configuration.html#configuring-settings-file

As @bettinardi mentioned, it is not very easy to debug without looking at the setup. It seems like you have a sub-balancing step for your seed geography (TAZ) in the run_list. You cannot have a sub-balancing step for the seed geography. Try correcting that and see if it fixes the issue for you.

Reading through the entire wiki will be very helpful. There are links to additional resources including a training package here: https://activitysim.github.io/populationsim/docs.html#external-resources

@binnympaul @bettinardi Thank you so much for your reply. As @binnympaul pointed out, the sub-balancing setting seems to occur the error which I have encountered. After fixing this setting with non-seed geopraphy, the program is running well now. I appreciate your suggestion.

That's great to hear - I hope you have a good experience with PopulationSim moving forward.

This looks resolved - hopefully I'm closing correctly
