undefined symbol: _ZN6caffe26detail37_typeMetaDataInstance_preallocated_32E

I constantly get this error below when I run python generate.py configs/demo.yaml on Ubuntu 18.04 anaconda3 cuda 9.0

Can anyone please help? Thanks!

@spha-code, @fujingling , or others - did you ever solve this issue? I am also having this error.

I had a similar error:/occupancy_networks/im2mesh/dmc/ops/_cuda_ext.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZN6caffe26detail36_typeMetaDataInstance_preallocated_7E I solved it by reinstalling a matched version of torch and torch vision.
