What model is causing the crash? What are your chunk settings? Have you been able to run the model to completion with a smaller household sample size? I would try...
@ray-ngo Here is the documentation for multiprocessing: https://activitysim.github.io/activitysim/core.html#multiprocessing When using mp without chunking, ActivitySim breaks the 'problem' (where the problem is often a very large table of choosers and alternatives)...
Some good ideas [here](https://pandas.pydata.org/pandas-docs/stable/user_guide/enhancingperf.html) to increase pandas performance. The Pandas eval function looks interesting. Could it replace/substitute python eval in some cases?
Oh good to know-Thanks for pointing that out!
@jpn-- Not sure if you are the right person for this issue, but issue #589 reminded me that this one is still open.
@jpn-- Thanks. For us, it was a bit of a surprise (and not at all obvious) to find out that a constant was being used for this transit component instead...
@jpn-- How about adding this field as 'optional' under the Land Use section with a brief explanation. As mentioned above, the field is used in the tour mode choice pre-processor...
@gbrawn We are able to run it on a machine with 128 GB of RAM, which requires an initial run using chunk training. Also, just to be clear, the PSRC...
@jpn-- @bricegnichols and I put together the attached skim definition spreadsheet and we are hoping it can be the starting point for a table that gets added to the documentation....
@toliwaga the last option seems good. How about also adding an additional comment to every non-configurable setting, such as: this must be 'zone_id'; it is not configurable.
