Error trying to prepare s3dis #23

Open katadam opened 3 years ago

katadam commented 3 years ago

Hello, thanks for the code.

When I am trying to prepare s3dis for fine tuning I get the following error.

line 104, in convert_to_ply inds, collabels = ME.utils.sparse_quantize( ValueError: too many values to unpack (expected 2)

Could you elaborate please?

You probably use a different MinkowskiEngine version than them, as the sparse_quantize functions returns change for different versions (especially at ME 0.5 there are no collabels any more)
