• Technical Admin
  • New issue from PSRC: #830 PSRC Model crashes during non_mandatory_tour_frequency when compiling sharrow
  • New issue identified in SEMCOG implementation: #837 los.py expecting number of TAZs in land use to match length of skim index
  • New issue identified in SANDAG ABM3 implementation: #841 Non-mandatory tour frequency occasionally removes row from choosers table
  • New issue #842 overflow in utility term calculation
• Phase 9a Updates
  • The engineering team is close to a runnable BayDAG example model and are working on testing BayDAG with sharrow
  • In updating to Pandas 2.0, there were major runtime problems when running in non-Sharrow mode, possibly due to Eval function. It was decided to not upgrade at this point because it is not critical path for optimization work.
  • Discussion on Pyarrow versus block memory management
• Planned for Next week
  • Closing out all BayDAG PRs
  • Addressing bug fixes
  • Run BayDAG end-to-end (but may not be sharrow-enabled yet)
