Thanks. It is super helpful that you're doing it. Just to check before I'll try to debug it - do you have any buildings which are not within enclosures? |

Thanks for your quick help! I'm fairly sure I don't have any buildings which are not within enclosures – I ran buildings = buildings[buildings.within(boundary['geometry'][0])]and enclosures = enclosures[enclosures.within(boundary.buffer(1)[0])]before running len(buildings[buildings.within(enclosures.unary_union)]) == len(buildings)it returns |

Hmm, I am not able to reproduce this. If you are not able to create a reproducible example, can you pass me your data and Jupyter notebook (via Teams somehow)? |
|
I've got minimal-ish examples which show the error – I'll try to send these via Teams |

Sorry for submitting so many issues recently, but I ran into an error when trying to run
momepy.Tessellationthat I have been unable to decipher and any help in diagnosing would be greatly appreciated!When I run
it will run for ~fifteen minutes (on data with 81277 buildings and 5731 enclosures, so taking a while is expected) before failing with
IndexError: index 0 is out of bounds for axis 0 with size 0. I unfortunately haven't been able to reproduce the error, so assume it must be some quirk of my data, but I haven't been able to find anything obviously wrong –buildingsandenclosuresall look as expected and theuIDs for thebuildingsare all valid.The full traceback is below – I'm fairly sure that the many
