I meet this problem: ImportError: cannot import name 'C_ROIPooling' from 'common.lib.roi_pooling' (/home/wenhao/project/VL-BERT-master/pretrain/../common/lib/roi_pooling/init.py) And I don't know how to solve.plz.

compile with command: ./scripts/init.sh

@haozidede Thanks for your kind reply. @WorthHouse You need to run the ./scripts/init.sh to compile the operators.

In code, common/lib/roi_pooling/roi_align.py, it does

from . import C_ROIPooling

it outputs error

ImportError: libtorch_cpu.so: cannot open shared object file: No such file or directory

I try to run the following code again, 

./scripts/init.sh

it outputs

It seems my installation is correct. Could you @huangyz0918 @jackroos tell me why this error happen?

Thank you in advance.
