When use lgf.compute_structure_environments module. And error " 'MaterialsDoc' object is not subscriptable

[Aiartanis]

Get the StructureEnvironments

When I follow the Supporting infomation. i meet the problem. Please help==。

se = lgf.compute_structure_environments(maximum_distance_factor=1.41, only_cations=False)

Please provide a runnable code snippet that triggers the error. From your screenshot, it looks like you're passing in a MPRester MaterialsDoc rather than a Structure instance to LocalGeometryFinder. If your MaterialsDoc contains a structure, try passing in doc['structure'] instead.

i am very sorry, i tried the cif and it works。
maybe the link from Materials Project is failed
thank you Very much

The object returned by mpr.materials.get_data_by_id() is a MaterialsDoc, not a Structure. If you access it's structure key rather than the passing the doc itself into lgf.setup_structure(), I think it should work.

oh……maybe i need try again ☺☺
Thank you !!
