Index Issue

Hi,

I am quite new to python, and I am trying to create a python script in Visual Studio. But I am receiving the following error message. Is there a solution?

Many thanks Blake

Hi @BlakeatFrasers not sure about this, seems to related to pandas / geopandas dataframe. Could you check your osmnx / pandas / geopandas installation? What happens if you print aoi & df variables?

Thanks for the quick reply @chrieke

osmnx seems to be causing the issue. This was fixed by re-installing the package. The version re-installed was 1.2.2, if this helps.

Cheers Blake
