The dataset generation failed because of a cast error
Error code: DatasetGenerationCastError
Exception: DatasetGenerationCastError
Message: An error occurred while generating the dataset
All the data files must have the same columns, but at some point there are 5 new columns ({'day_index', 'weekday', 'is_weekend', 'weekday_fa', 'date'}) and 12 missing columns ({'activity_id', 'crew', 'duration_pess', 'name_fa', 'duration_ml', 'name', 'predecessors', 'elec', 'start_lock', 'duration_opt', 'crane', 'super'}).
This happened while the csv dataset builder was generating data using

Project installation scenarios
Synthetic 36-activity / 4-resource installation DAG for the Project RCPSP demo.
Live Gradio app and organization card: alirezaaminzadeh/project and AriaAICompany/project. Collection: Aria AI — Services.
Generated data, seed 24. Names, durations and resource demands are synthetic. Optimistic / most-likely / pessimistic columns are three fixed scenarios, not a calibrated finish-date probability.
Files
- data/activities.csv
- data/resources.csv
- data/milestones.csv
- data/calendar.csv

Horizon
Working-day index 0 is Monday 5 Oct 2026. Weekends are skipped. Time unit is one working day.
The three mechanical set activities (A-12, A-13, A-14) each need the crane, so a feasible plan serializes them. Unconstrained CPM does not.
