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)
