After successfully compiling pointgroup_ops, I try to import it. However, there is an error:
pointgroup_ops/point_group.cpython-37m-x86_64-linux-gnu.so: undefined symbol: _ZN6caffe26detail36_typeMetaDataInstance_preallocated_7E

I use torch 1.1.0, torchvision 0.3.0, spconv 1.0, python 3.7.7

Hey, I met a similar issue. Did you figure it out?

The one I got

ImportError: /path/to/the/master_dir/PointGroup/lib/pointgroup_ops/PG_OP.cpython-37m-x86_64-linux-gnu.so:
undefined symbol: _ZN6caffe26detail36_typeMetaDataInstance_preallocated_7E
