forest-fire-mesa4-fix

Updated Forest Fire notebook compatible with Mesa 4.x.

The Problem

The original forest_fire notebook uses deprecated Mesa 2.x APIs:

• BatchRunner → removed in Mesa 4
• fire.run_model() → deprecated
• fire.dc → renamed to fire.datacollector
• df.BurnedOut → column is "Burned Out" in batch_run output

The Fix

This repo provides a working Mesa 4.x compatible version of the forest fire example with:

• batch_run() instead of BatchRunner
• Updated DataCollector access
• Correct column names
• SolaraViz visualization

Usage

pip install mesa[solara]
python forest_fire_m4.py
solara run app.py
