具体报错：
ImportError: /home/yourid/anaconda3/envs/vilbert-mt-rcnn/lib/python3.6/site-packages/torch/lib/../../../../libstdc++.so.6: version `CXXABI_1.3.11' not found (required by /home/yourid/anaconda3/envs/vilbert-mt-rcnn/lib/python3.6/site-packages/torch/lib/libtorch_python.so)
解决办法：
将anaconda3/lib中的libstdc++.so.6复制到报错提示的目录lib下，即：
cp "/home/yourid/anaconda3/lib/libstdc++.so.6" /home/yourid/anaconda3/envs/vilbert-mt-rcnn/lib/python3.6/site-packages/torch/lib/
解决。
