The error occurred while running the example "mesa-examples/examples/forest_fire/Forest Fire Model.ipynb". #228

There are two main errors. The first one occurs when running from mesa.batchrunner import BatchRunner. er1 When I changed the previous error part to import mesa.batchrunner, the program continued to run. However, an error occurred again in the sixth code block. er2 I'm not sure if these two errors are related, which makes it a bit difficult for me to know how to proceed. I hope someone kind can help me resolve this issue.

BatchRunner was removed a while ago (in https://github.com/projectmesa/mesa/pull/1689), we replaced it with batch_run.

You can either update the example (an PR is appreciated!) or use an older Mesa version, I think v1.2.0 is the latest version that supports the old BatchRunner.

Thanks for your suggestion, but the second issue is still not resolved. The error shows "'ForestFire' object has no attribute 'dc'." This might be a separate issue?

It’s probably just datacollector instead of dc, could you try that?

The answer is in the code :)

Thanks, the problem is solved! Next time I'll make sure to read the code carefully first...

No worries, and feel free to open a PR to fix it in our example!
