AttributeError: 'DataFrame' object has no attribute 'ix'

[johndehart]

I'm working through your introduction tutorial and I have hit a snag at item [13] for the patch report. When I execute the code its returning https://pynetlogo.readthedocs.io/en/latest/_docs/introduction.html

It looks like this may be related to versions of pandas > 1.0.0 (I have 1.2.4 installed). It was suggested to modify ix to loc or iloc []https://stackoverflow.com/questions/59991397/attributeerror-dataframe-object-has-no-attribute-ix

I updated 'patch_report' in pyNetLogo/core.py and its now working was: results_df.xi[:, :] = resultsvec.reshape(results_df.shape) is: results_df.iloc[:, :] = resultsvec.reshape(results_df.shape)

Let me know your thoughts... thanks

exactly on which pynetlogo command do you get the error?

It seems that all references to ix have been removed from master, so it should be possible to release a new version of pynetlogo that fixes this issue.

This issue starts with notebook cell [13] from []https://pynetlogo.readthedocs.io/en/latest/_docs/introduction.html

Facing the same error when running netlogo.patch_report("countdown") (from the examples). I'm using pynetlogo 0.4.2 and pandas 1.4.3. Here's the stacktrace:

All references to .ix are gone in master, and the notebooks run successfully.
